Electric bicycles are fantastic, but they are also an investment, and a crucial component of that investment is the battery. Unfortunately, just like your old phone now needing to be charged every five minutes, electric bicycle batteries inevitably degrade over time and lose some of their capacity. If you want to learn how to keep your electric bicycle battery healthier for longer, check out our expert tips and advice.



1. Pedal effectively and use gears



The fewer times you charge and discharge the battery, the longer its lifespan. It makes sense to try to find a balance of power during each ride, meaning pedal wisely.



Electric bicycle motors are designed to work with a normal to high pedaling cadence; they're most efficient and consume the least amount of energy. Bosch recommends keeping your cadence above 50, avoiding slow grinding, and making full use of the lovely gear distribution that comes with your bicycle.



Similarly, make full use of the modes provided with your electric bicycle—ideally, you want to use the lowest power setting you can handle to seek greater range, but not if it slows down your cadence to a crawl.





2. Avoid full charging and discharging of the battery


Batteries themselves have built-in computer chips to regulate their output and charging. This means they will never completely deplete and ruin themselves in the process.



However, performing full charges and discharges on the battery every time you go out does impose a higher load on the battery. So, if you consistently go out with a fully charged battery and then bring it back inside, you'll need to rinse and repeat. Instead, try to stop riding before the battery is completely drained on each ride... easier said than done.



3.Charge the electric bicycle battery at room temperature


Now, this is a big one. Charging the battery at room temperature is crucial, with the ideal temperature being between 10-20°C (50-68°F), definitely not below freezing. ChamRider advises charging the battery indoors, in a dry place with a smoke detector (lithium-ion batteries have proven to be very safe, but in extremely rare cases, they can catch fire if short-circuited). Charging outside of this temperature window will result in reduced range and shorter battery lifespan, as colder objects have increased resistance, causing a decrease in electrical capacity.



Riding for a few hours in cold weather is not bad for your battery since it will reach a certain temperature regardless of the environmental conditions. However, starting from warm is important. This means that if you're driving a van, place it in front of you and the heater, and put it on the bike immediately before riding. Also, avoid taking it directly from a cold shed; warm it up inside beforehand.




During the summer, don't leave it in direct sunlight either, just like your phone, as high temperatures increase the load on the battery. In theory, if the battery overheats, the motor will automatically shut off, just like on a laptop, but we haven't experienced such a situation.

Avoid fully depleting or fully charging the battery

If you haven't ridden your electric bicycle for a few days, weeks, or months, it's important not to leave it fully charged or completely drained. Bosch recommends keeping it at around 30-60% capacity, while Shimano suggests keeping it at 70%. Recharge the battery every 6 months, and of course, fully charge it before riding again.



Avoid excessive water usage around the motor and battery area



Clean carefully, avoid high-pressure cleaning

Bosch suggests removing the battery before cleaning the bike, while Shimano recommends keeping it in place to protect the terminals. Shimano's advice may be more practical in real-world application as there can be a significant exposure of wires splashed with mud and water if the battery is not installed.



We believe the best approach is to gently clean it vertically with a hose and sponge, then let it dry completely before opening it up.



Tips and Tricks



ChamRider suggests that if there is dirt or grime on the battery terminals (not the battery itself), you can clean them with a soft, dry brush or cotton swab.



Finally, reach out to the dealer who specializes in your motor and check the status of your battery. They will be able to inform you about the battery's condition and whether you're in a long-term storage situation or if there is any equipment damage.

Four

Electric bicycle questions you're afraid to ask:




1. Why does the charger get hot?



Converting the UK's 240V voltage to 36V for ChamRider results in some energy loss in the form of heat, typically around 10%, according to ChamRider. Charging automatically shuts off when the capacity is reached, so there is no overcharging or increased load.



2. Can battery manufacturers open the casing and replace a faulty battery like Tesla does?



No, it is not possible because the batteries need to be perfectly matched to avoid overcharging or over-discharging. It is technically feasible but a complex process, which would cost more money – acceptable for a £100,000 car but not for a £5,000 electric bicycle. As a point of interest, the Bosch PowerTube 625Wh battery has 50 individual cells inside.



3. How many cycles can the battery endure?



It depends on how you treat it. ChamRider states it can be charged up to 1,000 times, equivalent to normal usage for 7-10 years before the battery capacity starts to decline. Obviously, you would replace the bike before that, so theoretically, it can extend the lifespan of the bike. ChamRider guarantees that after 1,000 charging cycles, the battery will retain at least 60% of its original capacity.



ChanRider's warranty guarantees that within the warranty period (24 months after purchase, or 36 months from the date of battery purchase), the 400Wh, 500Wh, and 625Wh batteries will have at least 60% of their original energy capacity, and the 300Wh battery will have at least 70% of its original energy capacity. This is based on proper maintenance or 500 full charging cycles, whichever comes first. The brand states that with proper care, the lifespan can be much longer, as supported by lab tests and customer feedback.



4. Where do the batteries go when they are depleted?



Battery dealers, whether for bicycle batteries, phone batteries, or car batteries, have a responsibility to recycle the batteries. Different battery recycling programs exist throughout Europe, and in the UK, Valpak operates the largest compliance scheme. Interestingly, the UK tends to export its battery waste rather than recycling it domestically, primarily to France, Germany, and Poland.

Introduction:

With the arrival of winter, extra attention must be paid to the maintenance of electric bicycle batteries. Low temperatures can significantly affect battery performance and lifespan. In this blog post, we will explore some expert tips and practical information to help you keep your electric bicycle battery in optimal condition during the winter season.


Storing the Battery in a Temperature-Controlled Environment:
Extreme cold can have a negative impact on the capacity and overall performance of electric bicycle batteries.

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 electric road 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.





Learning from the lessons of other digital devices


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.



Use it sparingly as needed


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.







Rethinking the "free" speed


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.






Cost:


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.



Associated Costs:


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.



Energy Density:


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.



Discharge Capacity:


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.



Efficiency:


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.




Application:


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.



Which battery is best for electric bicycles?


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.



What is the lifespan of an electric bicycle battery?


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.



How Many Years Should An Ebike Battery Last?


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.
