Your electric bicycle battery is quite expensive. Understanding how to charge and maintain it correctly can extend its lifespan by 2 to 3 times. There are also some things to avoid that can significantly shorten the battery's lifespan. This article will tell you:
What to do when your battery is new
Basic electric bicycle battery charging guide
How to store it when you're not riding for a while
Lithium-ion batteries and safety
How to prolong battery lifespan
Charging with a "smart charger"
These guidelines and instructions assume that you purchased the battery together with the motor or electric bicycle, and their power and charging capacities are matched accordingly.
If you purchased them separately, you will need to learn more information to ensure you have the correct battery and there are no potentially dangerous combinations. Ideally, the battery should provide more capacity than the motor requires, and the charging speed should be faster than the charger's charging speed. Both have room to spare, so your battery won't be stressed, making it safer and prolonging its lifespan.
Lithium-ion batteries require minimal maintenance. The battery's longest range is achieved when it is charged between 30% and 80% capacity. Unlike other chemistries, lithium-ion batteries do not have a memory effect and can be topped up as needed.
Before use, it is recommended to fully charge the battery. For the initial charge, you should charge the battery to 100%. If time permits, leave it on the charger for about 12 hours to ensure an even distribution of battery charge. Afterward, if you have a smart charger, you can charge it to 80% or 90% to extend battery lifespan. Then, every few months or so, perform a full 12-hour charge after a deep discharge to recalibrate the battery.
The battery can be charged on or off the bicycle.
First, plug the charger into an AC power outlet. If there is a switch, turn it on and then off. This charges the internal capacitors of the charger and prevents a surge current to the battery.
Next, plug the charger into the charging port of the battery, and if there is a switch, turn it on. Most chargers have a set of LED lights. One of them will be red during charging and turn green when the battery is fully charged. When the indicator light turns green, the charger is not charging the battery and should be disconnected.
Ensure that the battery is not near flammable materials during charging.
For Electrify Bike Co batteries with switches, turn them on before charging.
Disconnect the charger when the green light is illuminated.
Charge the battery when the remaining capacity is between 30% and 60%.
Partial charging extends battery lifespan more than full charging.
Do not charge below freezing or above 50°C (120°F).
Perform a 100% charge every 1-3 months.
When you are not riding your electric bicycle temporarily, there are two crucial things to consider when storing the battery: the charge percentage and the temperature. If you plan to store the battery for more than a few weeks, you should set its charge level between 40% and 70%. Do not store the battery at 100% charge as it will shorten its overall lifespan. Additionally, avoid storing the battery with a charge level below 40% as the capacity may degrade over time. If it falls below its low-voltage limit (around 2.6-2.8 volts per cell), it may become permanently damaged and might not be rechargeable thereafter.
During long-term storage, it is advisable to periodically check the voltage and recharge it to above 50% as needed. This frequency can range from every 3 to 6 months.
Keep the battery at a moderate temperature. Lithium-ion batteries that are partially charged tend to have a longer lifespan when stored in a cool place. The worst combination is high voltage (100%) and high temperature. For long-term storage (several months or longer), store the lithium-ion battery at approximately 50% charge. Ensure that you do not leave the battery in a place where the temperature may rise above 120 degrees Fahrenheit for an extended period, such as a closed vehicle or a building without climate control.
If the temperature drops below 32 degrees Fahrenheit (0°C), do not charge the battery, as it may be damaged. Place the battery indoors and allow it to warm up before charging. Discharging the battery (riding the bicycle) is possible in cold weather, but it will reduce your range. However, it will not harm your battery or shorten its lifespan. Conversely, if the temperature exceeds 120 degrees Fahrenheit, do not charge the battery, as it may also be damaged.
Lithium-ion batteries can pose a fire hazard. This risk is significantly reduced if you purchase high-quality batteries from reputable sources that use branded cells. However, the risk increases if any cells within the battery are damaged due to drops or exceeding charging/discharging limits. Do not leave charging batteries unattended, and avoid charging them near flammable materials. If the battery is visibly damaged due to drops or water exposure, it should be recycled and replaced.
Failure to charge lithium-ion batteries in accordance with the following guidelines can shorten their lifespan and pose significant safety hazards.
Lithium-ion Battery Charging Temperature:
0°C to 45°C (32°F to 113°F)
Lithium-ion Battery Discharging Temperature:
–20°C to 60°C (–4°F to 140°F)
Extreme Temperature Guidelines:
Charge at reduced current below 41°F.
Charging below freezing is not permitted.
Good charging and discharging performance at higher temperatures but with a shorter lifespan.
Lithium-ion batteries, unlike some other technologies, do not have a memory effect, so you can charge them at any time without fully discharging them. When charged to 100%, it is expected to go through about 300-400 full charge cycles before the battery capacity drops to 80% of its original capacity. In terms of range, this means that if your new battery can travel 20 miles at 80% capacity, it will only travel 16 miles after 300-400 full charge cycles.
The simplest way to extend battery lifespan is to only charge it to 80% or 90% when you won't be riding for a few days. Most recreational rides don't require a full charge anyway. Doing so can extend the battery's lifespan by 2 to 4 times. Charging to 90% will give you around 1000 charge cycles, while charging to 80% will give you around 1600 charge cycles. This is similar to how you treat your smartphone. After charging it every day for a year, you'll notice that its talk or screen time is only 80% of what it used to be.
If you know you're going on a long ride and want to ensure the battery has enough charge, feel free to charge it to 100%. Doing so before a ride won't shorten the battery's lifespan. To control charging at 80% or 90%, you would need an "advanced" or "smart" charger that has this feature. Most chargers that come with electric bicycles do not have this capability.
If you use a smart charger to extend battery lifespan by charging to 80% or 90%, you should occasionally (every 2-4 months) balance the battery. To do this, you'll need to perform a deep discharge (below 30%) and then charge the battery to 100% to give the battery management system (BMS) a chance to rebalance the battery for maximum capacity.
Subjecting the battery to high drains will shorten its lifespan. If your battery is rated for a continuous power of 40 amps, it doesn't necessarily mean you should run it at that power for extended periods. If your battery feels hot to the touch during use, it may indicate that you're drawing too much current for too long. The BMS of the battery may allow you to draw more current when needed, but you should be aware that it should not be abused.
Avoid charging the battery too quickly or too frequently. Just like electric cars with fast-charging stations, you can also fast-charge electric bicycles. Electric car manufacturers warn against relying solely on fast-charging stations as it can shorten the lifespan of the car battery. Unlike fast chargers for cars, most electric bicycle fast chargers operate within the safe charging limits of the battery and do not shorten its lifespan, unless you have found and purchased an ultra-fast charger.
For example, all the batteries used by Electrify Bike Co. can be charged at 1.5 amps without decreasing the battery lifespan. Our popular battery, the Super Shark, consists of 14 series cells and 4 parallel cells. Four times 1.5 amps equals 6 amps, so the charger can charge at a current of 6 amps without reducing the battery lifespan. Our fastest chargers are only four and five amps, which is two-thirds of the safe charging level. Each battery also has a safe fast-charging rating, but frequent use may decrease the battery lifespan. This rating is approximately 2.5 amps per cell, so a 4P battery has a rated current of 10 amps. Even the Electrify Bike 2P Mini-Max battery can handle a 5-amp charge without reducing the battery lifespan. This is one of the many advantages of using high-quality batteries in battery manufacturing.
Smart chargers can automatically stop charging when the battery reaches 80%, 90%, or 100% capacity. This can be selected using a rotary switch at the end of the charger. Electrify Bike Company offers smart chargers in 2-amp and 4-amp sizes, suitable for 36V, 48V, 52V, and 72V batteries. We also provide advanced smart chargers with the same voltages and an additional rotary switch to select 1 to 5 amps. The advanced smart chargers also feature a display screen with switches to show voltage and current.
The recommended way to use a smart charger is to charge to 90% after each ride, so your bike is always ready to go. Then, if you're planning an extended ride and want to ensure maximum battery range, you can charge it to 100%. Charging the battery to 100% before a ride will not have a negative impact on battery lifespan.
The speed at which the electric bike system disconnects and your riding style are crucial for battery performance. Almost all major bicycle manufacturers now offer a range of road and off-road electric bikes.
From cargo commuting e-bikes to sleek carbon fiber electric road bikes that are almost indistinguishable from non-motorized bicycles, electric bikes have evolved from novelty to practicality in the cycling world.
Anyone who has invested in battery-powered consumer electronics can attest to the noticeable decline in battery performance over time. Therefore, for anyone considering purchasing an electric bike and existing owners alike, e-bike battery maintenance is an important consideration.
The best electric bikes

The best commuting electric bikes
With the rapid pace of development, some potential electric bike owners are concerned that the premium they pay today will be frustratingly outdated in a few months. This is not entirely accurate and largely depends on your usage.
Take the electric bike motor, for example. Mid-drive motors come in two rated output powers: 250W and 500W. More powerful motors may be enticing, but they also consume more battery energy. For regular commuting, a 500W motor is almost entirely unnecessary.
As more research and development resources are poured into the electric bike market, mid-drive motors may become more efficient or lighter, but riders don't necessarily need greater output power. The key is finding the right balance between power and efficiency based on your specific riding needs.
What you should consider is battery technology and how the usage of an electric bike affects battery life.
Battery suppliers in the electric bike market have chosen lithium-ion as the standardized chemistry. This battery composition has been validated in consumer electronics and automotive industries. Therefore, there is a wealth of user data available regarding the health of lithium-ion batteries.
The motor of your electric bike will last a long time, with fewer moving parts prone to damage or heavy maintenance. Where performance may decline over time is in the battery pack.
Most smartphone or laptop users have experienced battery degradation over time. However, the loss of energy capacity can be mitigated. The most crucial impact on the health of electric bike batteries is the frequency of charging from very low energy levels.
If you frequently drain the battery to almost empty in most rides, the likelihood of significant degradation is very real. Ideally, you want to minimize the time spent at zero energy consumption and at 100% energy consumption.
Most electric bikes come with three-mode configurations, roughly divided into thirds. The lowest pedal-assist mode uses one-third of the available motor power, the middle setting uses two-thirds, and the third setting provides full power.
By default, using the eco mode, you should complete your electric bike rides with the maximum battery capacity possible.
Limiting the depth of discharge is the most important way to maintain the health of electric bike batteries.
While we all occasionally enjoy maximum motor assistance, it is quite unnecessary, especially considering the lower limits imposed on electric bike systems in the EU/UK, which are set at 25 km/h.
The only time you should use the full power of the electric bike is when conquering the steepest slopes during challenging climbs.
By judiciously using only the battery capacity you need and not excessively consuming all the extra watts, you will enjoy better and more stable battery health over time.
The electric bike motor also prefers a consistent cadence, preferably in the range of around 80 RPM. To achieve the best match between your input and the motor's output, it is better to ride with higher cadence and lower gears.
If you frequently ride your electric bike and fully deplete the battery, you may consider models with larger battery capacity. Alternatively, you can choose plug-in range extenders to balance the overall load of the electric bike's energy system.
Different countries and regions have different regulations regarding the speed and specifications of electric bikes.
In the United States, the maximum power limit for electric bike motors goes up to 750W and disengages assistance at speeds of 32 km/h. Europe and the UK have adopted stricter definitions, with a power output limit of 250W for electric bikes used on roads, disengaging electric assistance at 25 km/h.
As a result, electric bike riders in the EU and the UK generally experience less battery degradation due to the configuration of their bikes. By using more conservative pedal-assist software to manage their energy usage, electric bikes in the EU/UK theoretically operate more efficiently than similar products in the US market.
Commuting and active transportation electric bikes were never designed to be speed machines. The value of these pedal-assist bikes lies in alleviating the challenges of long-distance commuting along hilly routes or reducing the pain of riding against the wind on the way back home in the afternoon.
Electric bikes are most useful when enhancing the rider's power on steep climbs or against headwinds. In both cases, speed is low. Active commuters don't need to climb steep hills at 40 km/h.
For electric bike enthusiasts in the EU and the UK, the more conservative assist setting of 7 km/h for mid-drive motors can provide an excellent ownership experience and contribute to healthier long-term battery health.
The differences between lead-acid batteries and lithium-ion batteries on electric bicycles are quite apparent.
Lead-acid battery systems can be several hundred or thousand dollars cheaper than comparable lithium-ion batteries.
Currently, the price range for lithium-ion batteries is between $5,000 and $15,000 (including installation costs), and this range may vary depending on the size of the required system.
The purchase and installation costs of lead-acid batteries are generally cheaper than lithium-ion batteries.
The cost component of lithium-ion batteries is higher; however, the lifespan value of lithium-ion batteries offsets this impact.
The energy density of lead-acid batteries is much lower than that of lithium-ion batteries. Lithium-ion batteries have significantly higher energy density compared to lead-acid batteries.
Lithium-ion batteries can store more energy in the same physical space. Additionally, they can release more energy, providing power for a longer duration.
The discharge capacity of lead-acid batteries should not exceed around 50% as it can shorten the battery's lifespan.
Typically, lithium-ion batteries utilize 85% or more of their total capacity in a single cycle. Therefore, lithium-ion batteries have better effective capacity than lead-acid batteries.
The efficiency of lead-acid batteries ranges from 80% to 85%. These batteries charge slowly and have lower effective battery capacity.
Most lithium-ion batteries have an efficiency of 95% or higher, meaning that 95% or more of the energy collected in the lithium-ion battery can be utilized. These batteries charge quickly and have a larger effective capacity.
Lead-acid batteries are well-suited for large-scale stationary applications where space is abundant and energy demands are low. In terms of cost and size, lithium-ion batteries may be the ideal choice for electric bicycles.
Environmental Friendliness:
Lead is a carcinogenic and environmentally hazardous substance. Even lead-acid batteries contain dangerous compounds like sulfuric acid. Lithium-ion batteries are more environmentally friendly as lithium is a harmless substance.
For electric bicycles, lithium-ion (Li-ion) batteries are the best choice. While lead-acid batteries are still much cheaper, they are three times heavier than lithium-ion batteries.
Lithium-ion batteries are favored for their lightweight nature and suitability for long-distance travel. Compared to older battery technologies, lithium-ion batteries offer faster charging, longer range, and better power density, achieving longer battery life in lighter containers.
However, the five most critical variables to consider when choosing battery chemistry are specific energy, cost, lifespan, power, and safety.
With proper maintenance, the battery lifespan can range from 3 to 5 years. Even when not in use, lithium batteries on electric bicycles will gradually lose capacity and self-discharge.
Even if the connected electric bicycle doesn't require any power or remains unused, the lithium battery on the electric bicycle will lose the stored energy due to internal actions.
Excessive self-discharge can cause irreversible damage to the electric bicycle's battery. Therefore, it is recommended to actively utilize it.
Generally, a high-quality eBike battery may last between 3 and 5 years. Of course, this depends on various factors, including the type of battery, and how well you maintain it.
The major factors recommended for prolonging the e-bike’s battery life include the following:
Charge your battery completely for up to 4-7 hours before your first ride to extend its lifespan.
Use the original charger provided during the initial purchase with your e-bike; never mix and match chargers.
Do not wait until your e-bike battery is completely drained before charging.
Maintain your e-bike by charging it regularly and adequately.
Establish a charging station that is both dry and secure. Electrical gadgets should not be exposed to high humidity.
Learn your battery’s high and low voltage cut-off limitations.
Regularly clean around the battery connections and eliminate any corrosion.
Lithium batteries are the most prevalent battery in electric bikes nowadays.
Which is better, lead-acid batteries or lithium-ion batteries? In most cases, lithium-ion battery technology is superior to lead-acid battery technology due to its advantages in reliability and efficiency.
If the electric bicycle is not used frequently, the cheaper lead-acid battery may be preferred. According to recent research, the lifespan of lithium-ion batteries in electric bicycles is 45% longer than that of equivalent-rated lead-acid batteries.
All electric bicycles are powered by batteries, allowing riders to easily commute. Some electric bicycles have batteries that can be easily removed with a simple key. However, there are electric bicycles with non-removable batteries, which means that if the battery fails, you won't be able to ride in electric-assist mode. I will show you some tips and tools to make it easier for you to remove the battery.
Removing the battery from an electric bicycle is not a complicated task, but there is a significant risk of causing
serious damage to the battery if not done correctly. To avoid this, you must follow the proper steps.
Simply use a screwdriver to detach the seat.
Next, you need to unlock the battery. If you turn the key counterclockwise beyond the position where the key
can be removed, the locking pin should retract into the battery.
Allow the battery to drop down and take it out of the frame. After removing the locking pin, you should be
able to pull out the battery using the handle on top of the battery.
The tools required to remove an electric bicycle battery will depend on whether you want to remove the battery using the traditional method with a key or without a key. Here are some tools that may be needed to remove an electric bicycle battery:
- key
- Axle blade (only if you have lost the key)
- Screwdriver (in the case of a lost key scenario)
- Bolt cutters
- Electric Drill
Using common sense when handling your e-bike key will help you avoid these problems, whether you have a simple single-pin spring lock or some high-tech, expensive bike locks. If that doesn’t work, let’s review several methods for taking out your electric bike’s battery without a key in case you need to replace it or make emergency repairs.
A common household object can be used to drill or cut through a bike lock. Ordinary tools for drilling or cutting locks include some common home objects.
These include an electric drill and a bolt cutter. Power equipment like electric drills is particularly helpful since they can remove large amounts of stuff at once.
Professional lock pickers typically have the best tips for picking a bike lock. It’s worth noting that digital locks are nearly tough to pick.
Unlike typical locks, they are designed to be secure with electric power. Pressing a striking spring and the other pins and springs inside the lock can gradually unlock the lock. Until it gradually opens completely.
While removing the battery from an electric bicycle may seem straightforward and not overly complicated, there are some recommended practices to keep in mind.
For safety reasons and to maintain the health of the battery, it is recommended to remove the battery from the electric bicycle.
Additionally, when the external temperature exceeds 20 degrees Celsius or falls below 0 degrees Celsius, it is advised to take out the battery and store it in a dry, room-temperature environment to minimize stress on the battery.
Furthermore, by taking out the battery and keeping it indoors at home or in your workplace, it reduces the risk of theft.
Whether by choice or due to a depleted battery, an electric bicycle functions the same as a regular bicycle when the motor is not in use.
Regardless of the reason for riding without a battery, you can rest assured that it will not damage the motor or the bicycle. The only difference is that your muscles will bear the sole burden of propulsion.
The weight of an electric bicycle depends on the pedal-assist components and the inherent resistance of all the power system components. These factors will affect your riding experience without the battery.
Rad Power Bike batteries are difficult to remove because the battery terminals take up some space at the bottom, making it challenging to slide or pull the battery out by the terminals.
Therefore, you have to be careful to only push or pull the battery itself, not the terminals. Otherwise, your efforts will be in vain. Due to the battery and terminals being made of the same material and almost seamless, it's easy to forget this distinction.
Instead, look for any fractures. You must regularly lubricate the battery attachments to prevent them from becoming nearly hard to remove. You should lubricate the bike’s battery as well as the area where it attaches to the bike
When not using the bike, it is always advisable to remove the battery from the electric bicycle. There are a couple of reasons for this. Firstly, it is for safety considerations.
The cost of the battery is approximately one-third of the bike's cost, and electric bikes are more likely to be targeted by thieves. If an expensive bike is stolen, separating the expensive battery can mitigate the loss.
It is not foolproof since people can still ride the bike without the battery, so it doesn't completely deter theft. Most bike thefts are crimes of opportunity. If someone with questionable morals sees an unlocked bike while out and about, they might think it's easier to ride away with it. So they hop on the bike, ride to their destination, and ultimately, it disappears.
For instance, your e-bike now only charges up to 48V when it used to reach 54V. Additionally, it has become weak and sluggish, with a sharp drop in battery level when accelerating.
1. End of battery life:
Your battery may have reached the end of its life. However, it could also have internal damage due to various factors such as age, number of charge/discharge cycles, and more.
2. Improper battery handling:
Mishandling the battery, such as using an incorrect charger type or voltage, causing short circuits on the terminals, can also result in similar damage within a relatively short period.
3. Possibly defective battery:
If you notice the battery quickly draining even when not in use, it may indicate a defect in the battery you have. Remove the battery pack from the e-bike and charge it on a bench for testing.
After charging, without disturbing the bike, check the battery. If your lithium-ion battery cannot hold a charge, it indicates a failure.
Knowing how to remove the e-bike battery can assist you in various ways. I believe it is essential to consider both the aesthetics of the bike with the battery neatly tucked away and its practicality, as well as the importance of simply removing the battery and taking it with you to a secure location.
