When your electric bicycle needs a new battery, you have several options. It may take some time, but electric bicycle batteries do degrade over time. If your device is old and worn out, here are various choices to consider. Following the latest industry recommendations, which suggest replacing defective or scrap batteries with "authorized technically identical batteries," may not always be practical.
Batteries are the most expensive consumables on an electric bicycle, and replacing a battery typically costs several hundred pounds.The good news is that the quality of electric bicycle batteries is generally much better than in the early days of the industry. A two-year warranty is the minimum industry standard today, and the lifespan of high-quality electric bicycle batteries should be longer than that.
The bad news is that even with frequent use, electric bicycle batteries will eventually need to be replaced.
Electric bicycle batteries can fail in two main ways:
1. They may become unable to charge or provide power to the motor due to issues like faulty connections or a malfunctioning Battery Management System (BMS) chip.
2. Over time and repeated use, they may gradually lose capacity to the point where the range they provide becomes impractical. All lithium-ion batteries degrade with repeated use and charging. This, in itself, is not a fault, but it does mean that even the best electric bicycle batteries have a limited lifespan.
This is an important distinction because different battery warranties cover different battery faults. For example, ChamRider guarantees their own branded batteries to have at least 60% of the original charging capacity after 1,000 charge cycles . It is the dealer's job to determine the remaining battery capacity using diagnostic software. It widely quotes a guarantee of at least 60% of full charging capacity or 500 charge cycles within two years (whichever comes first) – although I was unable to find this information on their website.
However, many other companies may simply stipulate a two-year warranty. If your battery completely fails within two years, this should provide a clear solution, but if the available capacity drops significantly within that period, it may trigger various semantic debates.
Considering all the above factors, it is best to obtain as detailed a written battery warranty as possible from the retailer at the time of purchase. It must be said that finding a clear and detailed battery warranty on the websites of electric bicycle companies is a rather challenging task.
When does a battery degrade to the point of needing replacement?
By using an inline energy meter (such as this one), you can get a very approximate understanding of the capacity of your electric bicycle battery.
First, make sure your electric bicycle battery is completely depleted by using it until the battery is empty. You should know its rated capacity in watt-hours (Wh) – for more detailed information, refer to our battery article.
Now, charge it back up to full but use the inline power meter to measure the watt-hours consumed from start to finish (i.e., after the battery is fully charged).
Not all the electricity consumed by the meter goes into the battery. For example, the transformer that reduces the voltage from 240V to the voltage required by the electric bicycle battery is inefficient and loses some electricity.
Transformers vary, but a very rough working assumption is that 80% of the power from the socket ends up in the battery.
It's best to repeat this exercise a few times to get an average reading. Clearly, this method has its limitations, but it should at least indicate any very significant shortcomings in the battery's capacity and allow you to monitor it over time. If you notice a decrease in the battery's range, it can be used to help quantify the suspected performance decline.
If your battery is out of warranty, the next logical step is to purchase a like-for-like replacement. Even for electric bicycles that are a decade or more old, it is often still possible, particularly for models equipped with high-quality motor systems from brands like Bosch, Shimano, Yamaha, and Brose.
The industry advice is to only replace with a battery from the same manufacturer and with identical specifications. There are good reasons for this – the battery, controller, and motor are all designed to work together safely, and using a "non-original" replacement pack may introduce uncontrolled risks.
That being said, you can choose to upgrade to a larger capacity battery offered by the same manufacturer. Some Bosch and Shimano batteries of different capacities are explicitly interchangeable.
If your battery is out of warranty, the next logical step is to purchase a like-for-like replacement. Unfortunately, this is not always an option. Electric bicycle technology is constantly evolving, and older batteries may no longer be in production.
If your product is out of warranty and direct replacement is not possible, the next obvious step is repair or "rejuvenation" (replacing the internal cells of the battery with new ones). Rejuvenation undoubtedly carries risks, especially if you use a non-professional company, so choosing the right place for rejuvenation is crucial.
As we reported in February, the industry view expressed by CONEBI is that only original OEM-certified batteries should be used as replacements for electric bicycles. This is certainly the ideal choice for obtaining high-quality replacements, but it is often simply not possible for older electric bicycles.
Hannes De Jong runs Heskon, a leading electric bicycle recycling and repair service in Europe. He acknowledges the concerns raised by CONEBI but believes that with the maturity of the industry, refurbishment may be the way forward.
"While there are safety risks with using a small, inexperienced company for recycling or repair, I believe certification can address many of the concerns raised by CONEBI," he told us. "Most importantly, the new EU legislation that is currently being formulated should make repair/reuse the first choice."
Similarly, ChamRider notes that there are currently no clear rules specifying that repair and refurbishment services work with original manufacturers or even require them to recertify the batteries. This is precisely why De Jong wants to introduce certification standards so that professional companies like Heskon can provide reliable and sustainable services while strengthening legal standards.
Mid-drive motors of high quality have been around for decades, and there are now a large number of electric bicycles no longer in production with proprietary electronics in their original batteries. Of course, in many cases, the original suppliers and/or manufacturers of the electric bicycles cannot be traced or have ceased operations. This is where things get tricky.
Whether it is repairing completely failed batteries or, more commonly, performing a full recharge due to the decreased capacity from years of use, there are companies in the industry with a long history and good reputation. We interviewed two of them to delve into what can be done and what cannot be done.
Although electric bicycle battery refurbishment is a hot topic in the industry and not without risks, it has significant sustainable potential and should be organized and certified to provide cost-effective and safe options for old electric bicycles, especially when original battery replacements from the manufacturer are not available.
Recently, a reader contacted us and, after having problematic batteries refurbished at Ebike Batteries in London, they are back on the road. Another option implied by advice given by original manufacturers to customers is that the bike cannot be used as an electric bicycle anymore. This essentially means discarding a perfectly functional electric bicycle.
As a final note on battery safety, it is worth emphasizing that even with high-quality batteries, other equally important measures need to be taken.
Unsupervised charging should be avoided, especially overnight. Similarly, whenever possible, you should always use the charger provided by the original manufacturer.
The one that comes with the battery should be well-matched and not cause overcharging. Using a different charger may result in malfunctions during the charging process.
Using replacement batteries from non-original manufacturers (whether or not involving dealers) may also void the warranty for your electric bicycle or kit. Consult your electric bicycle or kit company to understand their policies regarding the use of aftermarket replacement batteries.
It may not be crucial if it allows you to continue using an old electric bicycle that would otherwise be scrapped, but as you can see from the information above, you may have other options to consider before going down that path.
The electric bike battery is one of the most important parts of an electric bike and without it the electric bike will turn into a regular bike.With this importance, everyone is trying to get the best performance from the battery in order to increase his enjoyment of the electric bike.
One of the most frequently asked questions: Why is my ebike battery draining so fast? In fact, this question is an important but somewhat confusing question.The reason for this is that the word FAST cannot be measured, meaning the battery drained fast, i.e. some 15 minutes of riding your ebike.
Or drained fast, meaning if you used to use the ebike for 20 miles per one charge, and now you go 15 miles per one charge? That is why in this post we will answer the question Why is my ebike battery draining so fast? from both sides.We will explain the reasons that lead to abnormal battery consumption and also the reasons that reduce the range of a single charge.
So that you have all the information you need to determine the causes of the battery problem and how to repair it.
As a general rule, the battery drains fast as a result of damage to the internal cells of the battery or a problem with the BMS.
1-Damage Cell or Group of Cells.
The first and main reason why the electric bike battery drains fast is that there is damage to a cell or group of cells inside the battery, and the reason for this is that when there is a damaged battery cell the voltage becomes lower than normal, so the BMS “battery management system” completely shuts down the battery to save the internal cells of the battery.
To understand this point better, let’s take a quick look at how the BMS works.
Inside the battery of your electric bike are cells grouped together and each group is connected in series and connected to the BMS.
Through this connection, the BMS measures the voltage coming out of each group.
BMS is programmed to a minimum voltage & when the battery cells reach it, the BMS turns off the full battery completely.
Based on this, if you have only one cell or a group of cells damaged, you will find that the battery drains very fast.
In order to solve this problem, the damaged cell must be identified by measuring the voltage for each group of cells using a voltmeter
2-BMS Problem.
The second reason that may lead to the battery draining quickly is that there is a problem with the BMS unit itself.
The reason for this is that the BMS, as we mentioned, is the controller of the battery, so if there is a problem with the BMS and it is unable to read the battery cell voltage correctly, It will cause the battery to shut down quickly and you will notice that the battery is drained abnormally.
To solve this problem, you can reset the BMS or replace the BMS. You can see this post to learn the correct ways to do REST for BMS
Why is my ebike battery draining so fast? (The reasons for the low mileage)
In this part of the post, we will explain the most important reasons that reduce the miles you travel with your electric bike on a single charge.
1-Using Super Fast Charger.
One of the reasons that reduce the performance of the battery in general and reduce the long term is the use of a very fast charger because this will strain the battery cells and reduce their lifespan.
Based on my personal experience, I have noticed that the number of miles I travel when charging my bike battery with the original charger is more than the miles I travel when I use the fast charger.
Of course, you will need to use a fast charger in some situations, such as you need to charge on the go in case you are away from home,but do not make the fast charger your first option.
You can check out this post to learn how to choose a fast charger that is suitable for your bike battery.
2-Wrong storage habit.
When storing your electric bike battery, you should follow the rules that help maintain the life span of the internal cells and or these rules are to keep the charge rate around 75%.
We wrote this post that explains the best steps that you can take to maintain your bike battery during storage.
3-Using throttle only.
When you rely only on the throttle while riding your ebike, this will lead to the battery draining fast because you are making the bike do all the work.
This will lead to the fact that the motor will need to consume a lot of watts, which will reduce the range of a single charge.
4-Going uphills too much
When you use an electric bike up a steep hill, it takes a lot of the bike motor to give you the right torque to go up the hill.
This will also increase the battery drain and reduce the range of a single charge.
5- Riding in hot weather.
When you ride your electric bike in very hot weather, this will affect the movement of ions inside cells, which makes the chemical processes that occur inside the cell difficult.
This will greatly reduce the duration of a single charge and generally, most high-quality BMS will shut down the battery if the internal temperature of the battery reaches a certain degree.
6-Loading a Lot of staff.
Another reason for the battery depleting quickly is loading many things on the bike or towing a trailer.
This will lead to an increase in pressure on the motor to produce the highest torque, which will increase the battery consumption and thus reduce the battery range.
The reason for fast battery draining (30 minutes or less) are often due to damage to some battery cells or a malfunction in the battery management system BMS
On the other hand, there are several reasons that lead to the battery draining faster than normal, including the frequent use of a fast charger that is not commensurate with the capacity of the battery, improper storage of the battery, loading heavy things on the bike, and riding the bike in very hot weather.
Also, the continuous use of throttle only while riding and riding uphills a lot.
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.
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.
It is important to understand that not all electric bicycles are the same, and you should inspect the battery before use.If you are interested in purchasing a used electric bicycle, you may also want to check the health of the electric bicycle battery.
This article will guide you on how to quickly inspect an electric bicycle battery in the shortest possible time.
Want to know how to check an electric bicycle battery?
There are five steps you need to complete to thoroughly inspect your electric bicycle battery:
Step 1: Charge the battery and remove it from the bicycle for preparation.
First, you must fully charge the battery. Afterward, remove the battery from the bicycle.
Step 2: Perform a battery load test using a multimeter.
To check the battery voltage, set the multimeter to the DC mode.
Step 3: Check the multimeter for accurate voltage.
If a negative reading appears during the measurement, the polarity of the probes is reversed.
Step 4: Test the current.
Compare the current reading generated by the multimeter with the battery's user manual. This will give you an idea of how the battery capacity should compare to its current capacity.
Step 5: Perform a resistance test.
Finally, use the multimeter to measure the resistance of the battery. Resistance is the attempt to impede the flow of current through the battery. If the resistance is too high, the battery may overheat.
The only tool you need is a multimeter to test your electric bicycle battery. A multimeter is a versatile and readily available tool for electrical measurements. They come in digital and analog variants, and can be obtained online or at any hardware store.
But what does a multimeter actually measure? It measures electrical quantities such as current, voltage, and resistance, among others, for batteries and other electrical components. More advanced multimeters may also test other types of values.
However, performing a simple battery test on your electric bicycle doesn't require those additional capabilities.
Typically, analog or digital multimeters are handheld devices with two probes. You should place the black probe on the battery terminal that corresponds to the negative end, and the red probe on the positive end when using the electric bicycle battery.
With indicators, you can assess whether the battery in an electric bicycle is in good condition and whether a specific electric bicycle battery purchase is worth it.
What parameters of the electric bicycle battery are you testing?
Whenever we talk about testing an electric bicycle battery, we mean testing the battery's voltage, current, and resistance.
What voltage should I look for on the multimeter?
For a battery with a rated voltage of 36 volts, the ideal range displayed on the meter is 28 to 36 volts. You can adjust this factor to fit the specific voltage of your electric bicycle. In general, if your reading is 10 volts or lower than the value specified in the manual, the voltage is too low and not recommended.
For a 52V battery pack, the measured voltage typically ranges between 58VDC and 42VDC. A 48V battery pack will produce voltages between 54VDC and 40VDC. However, measuring is just an estimate as evaluating any battery model requires considering many factors.
Different E-bike Battery Test Methods

How To Check Ebike Battery With No Tools (Road Test)
Testing the bike battery on the road is the best technique to determine its condition.
Steps to follow to perform a road test:
Take the electric bike on a flat road.
To prevent battery performance from being impacted, ensure the weather is comfortable.
Pick a road with little traffic.
Begin riding at full throttle.
Ride till the battery is entirely depleted.
The percentage of the battery health is obtained as test*100\battery original capacity.
Conclusion
Testing an e-bike battery comprises several steps, as seen from the above mentioned procedures. This is so because a combination of a battery’s load, voltage, current, and resistance determines the overall health of an e-bike battery. You may relax knowing that the battery in your e-bike is still in fine functioning condition if all of these figures are as they should be.
