Knowing the autonomy of your electric bike battery will give you a precise idea of the number of kilometers you can ride. Various factors can influence this, including the capacity of the cells, the way you pedal, the general condition of your two-wheeled vehicle, the reliability of the motor, the wind force, the quality of the surface, the weight of the bike to which you add the weight of the user or the ambient temperature. Moreover, it is essential to check the power of the device. For example, a 500 Wh model will be much more efficient compared to a 400 Wh model.
It is advisable to take note of the most popular battery technologies. The lead-acid electric bicycle battery costs only a few euros. It is heavier, but still offers a decent longevity, an average of 300 to 400 recharge cycles. The NiMH model, less heavy than the previous one, can support up to 500 recharge cycles while the lithium battery guarantees a life of 600 to 1200 recharge cycles.
It is evaluated in Wh or watt hour. To make a simple calculation, multiply the voltage of the electric bike battery (often 36 V) by its capacity (in Ah). The power, as for it, marks the autonomy of the vehicle. Generally, it should not exceed 250 W except if you move on your VAE unbridled. In this case, you have the opportunity to aim for medium or high end electric bike batteries between 400 and 500 Wh. In short, keep in mind that the more Wh and Ah the battery has, the more range it will enjoy.
The location of your bike battery will not impact your cruising speed. Instead, you should base your decision on how comfortable you want it to feel and how well it handles.
Thus, it is better not to install the battery on the luggage rack in case you want to keep a sporty use of your bike. The same is true if you want to keep a certain balance because the motor is on the rear wheel. If you want to keep a good maneuverability, it is not recommended to put it at the back of the seat tube. The best electric bike battery will be the one capable of stiffening the frame without damaging it and keeping the bike balanced while maintaining its agility.
It differs from one motor to another and is a function of the quality of the cells, but also of the capacity. In most cases, it is mainly the cells making up the battery of the EAB that rubs off on its weight. At present, a model of satisfactory quality weighs in at 2.5 kg. It is difficult to limit the weight of the battery since the designers focus on improving the autonomy.
Having a bike is great, but having one with a battery is even better. The performance of the vehicle makes it particularly popular, especially with hikers and cyclists. Want to know more about how it works? Here's everything you'll need to know about the electric bike battery.
As mentioned above, an electric bicycle battery is made up of :
It is easy to handle an electric bicycle battery. To begin, determine the location of the accessory. There are several choices: in the rack, on the frame of the down tube, or integrated into the down tube. If you have chosen the rack, make sure to unlock it with its key and check that there are no foreign objects in the sleeve. Then simply place the battery and turn on its switch. For installation on the tube, you can use the ergonomic handle to put it correctly in place. A small click will be heard when it is well installed.
It is crucial to take precautions when handling (using and charging) the electric bicycle battery. In this sense, it is recommended never to expose the battery to too much heat or too low a temperature. If the battery is completely discharged, do not leave it/store it in this condition. Avoid recharging it if it is still full. Set aside damaged batteries. They are a great danger in case of an accident.
If you don't have a top-performing electric bike battery, there are easy ways to extend the life of your battery without relying on its capacity. To do this, you can :
Lithium batteries are the most present on the market. Their unmatched efficiency and their exceptional weight/performance ratio are the main reasons. As a proof, they are also used in other daily use devices such as smartphones and laptops. Withstanding approximately 700 to 1200 charging cycles, this type of model weighs only 2 to 3 kg on the scale. The efficiency of such a battery is up to 90 %.
With a service life of over 3000 cycles, a high level of safety and low toxicity, the LifePO4 lithium battery is gradually setting itself apart from the competition. The only drawback is that its energy density does not rival that of a lithium-ion battery.
It is the most affordable type of battery today, with a price 4 to 5 times less expensive than a lithium battery. It provides up to 400 charge/discharge cycles in addition to being less prone to the memory effect. In spite of its good performance, the lead-acid electric bicycle battery fears the cold. It is larger and therefore heavier. This is why we initially used 2 batteries of 12 V each, with a total weight of 10 kg, to obtain a nominal capacity of 240 Wh associated with a range of 30 to 80 km.
Among its biggest disadvantages, we can mention the weakness of its life and its autonomy, its difficulty to be recycled and its hypersensitivity to a low temperature. It should be noted that you will enjoy 24 Wh with 1 kg of lead battery.
The nickel battery, mainly the nickel metal hydride or Ni-MH, is becoming increasingly rare, gradually giving way to the lithium battery. It is subject to the memory effect affecting its autonomy and to self-discharge, contrary to what most of us think. Of course, you have to wait for the complete discharge of the battery to be able to recharge it at the risk of reducing its capacity.
The accessory seems relatively light compared to a lead-acid battery. This type of model accumulates more energy even though its life span is very limited. It is capable of withstanding approximately 500 charge cycles.
Like any other battery, the battery of an electric bicycle is essentially used to store energy. It plays an important role in the proper functioning of the vehicle. Indeed, the motor will be able to drive the 2 wheels thanks to the energy provided by the battery. The instrument includes a case, a wiring, cells as well as a motherboard. It is this last one which integrates all the programming of the bicycle while managing in an intelligent way the electric assistance.
The case, for its part, protects the battery from shocks. The wiring allows you to connect different elements of your battery. Connected together via a cable, the cells store all the accumulated energy. The battery can be lithium (the most common), lead or nickel. Some are specific for installation on the frame while others are intended for the luggage rack.
The super-capacitor was initiated by the French group Veloci Industries in 2020. Instead of using a battery, the new generation of electric bikes makes use of a super-capacitor. Like a dynamo, this energy storage system is unique in that it no longer needs to be recharged to provide the necessary power to the motor. Its operating principle is simple: it accumulates energy when you pedal and then releases it when you brake to optimize consumption. The bike, on the other hand, has no chain or mechanical traction system.
You can set your cruising speed (average speed of 15 km/h) and pedal at your own pace. The bike itself weighs nearly 16 kg, the lightest of the EABs to date, with a price ranging from 1500 to 2000 €. The bike is meant to be ecological. It does not contain any rare metals since the super-capacitor is entirely made from a combination of aluminum and carbon. The lifespan of this innovative technology is between 10 and 15 years and it is 100% recyclable.
The electric bicycle battery is perfectly suitable for you if you have a limited budget. You can already get the lead-acid model for a few tens of euros, while the lithium-acid model does not exceed 800-900 euros. It can be mounted on the frame, on the luggage rack or on the seat tube. Moreover, it is removable.
On the contrary, the super-capacitor cannot be bought separately. It will always be accompanied by the U-Feel electric bike (available in 3 designs), all for a price of around 1500 to 2000 €. Although this is a first in the world of urban mobility, for the time being, the device is unfortunately not yet on the market. Which is a real shame.
The battery is the heart of your electric bike. It will guarantee you an all-electric assistance during your journeys. This modern and efficient power source has a decent range and can be used as a reliable means of transportation to work or for a pleasant ride in the countryside. Recharging is quick and easy.
As a rule, the battery of an EAB comes with a warranty of 6 months to 2 years. But after this period or when it reaches the end of its life, what to do? The answer is simple! You just have to send it to the waste disposal center, put it in a bin specifically designed for this purpose, bring it to an electric bicycle dealer or to a company specialized in the reconditioning of this type of accessory.
Most current electric bicycle batteries are removable. They can be removed without difficulty so that you can recharge them. With some brands, the same key is used to detach the battery and lock the anti-theft device. For others, the battery and the motor will be placed in the same block, which will simplify the use of the bike as a traditional model.
The bike battery weighs between 2 and 4 kg. If you notice differences in weight, it is mainly due to the capacity and the nature of the protective case. This one can be +/- heavy and robust according to the models. Adding the total weight of the battery to that of the EAB is of little interest. The current designers tend to miniaturize the new models to make them lighter without losing their capacity.
With a few exceptions, the electric bicycle battery can be used in any weather. To do so, it meets the IP54 standard, which ensures that it is splash-proof (water and dust). Thanks to the quality of the casing, it is also resistant to shocks.
In our opinion, the best brands of electric bike batteries in 2022 are :
The German brand Bosch was founded in 1886. Leader in many fields namely motorization, industrial equipment, household appliances and electric bike battery design, it is known for the quality, robustness and durability of its products. It offers 3 lines of electric bike batteries: the Powerpack, the PowerTube and the DualBattery.
Brose is known mainly for its motorizations. Indeed, its devices are very present on the Decathlon or Specialized electric bike models. To complement them, you also have the appropriate batteries, including the 630 Wh battery designed for bikes released in 2020.
This French brand does not only manufacture and market innovative and high-performance electric bikes (e-leisure, e-VTT, e-VTC, e-urban...). It also offers good quality batteries to make the use of your bike more comfortable. If you're looking for a new or reconditioned battery, you'll find what you're looking for at Gitane at a competitive price.
Shimano is no longer to be introduced to cycling fans. The Japanese company is known for its high quality parts and components, especially its bicycle equipment, including batteries that are a real added value to its Shimano Steps motor range.
Yamaha is a famous international firm working in the electric bike sector. This Japanese manufacturer covers just about every segment with its various offerings including rack batteries, downtube batteries, multi-location batteries coming in several capacities (400 to 600 Wh) and external crossover batteries.
The diagram below will help you to get an idea of the typical prices for each price range (entry-level, mid-range and high-end).
However, more expensive does not necessarily mean better.
We therefore advise you to always consult our ranking before deciding, rather than blindly relying on price ranges.
Remove the battery before cleaning the electric bike
Whether you want to wash or repair your electric bicycle, be sure to remove the battery beforehand and isolate it in a place that meets all storage conditions. If possible, avoid disassembling the battery, as electrolyte may leak out, which could be very dangerous to your health. Place it in an area not accessible to children.
Prolong the life of your electric bike battery
Adopt the right gestures and you will save a lot of energy while increasing the life of your battery. Store it at a temperature between 10 and 25°C. When you're not using your bike, always remove it. For long term storage, make sure the battery is charged to 40-60% and then recharge at least every 2 months. On the other hand, the easiest way would be to use it regularly.
Don't confuse battery power with motor power
The capacity of the electric bike battery is expressed in Wh or watt per hour while that of the motor (250 W maximum to get a certification) is evaluated in watt or W. You have an urban EAB and you often ride on flat terrain? Choose a 400 Wh battery. Also, with an electric mountain bike, look to large batteries that can deliver 625 Wh.
Replace or recondition an old battery
If your electric bike's battery is too old, proceed with a change or reconditioning. Normally, there are specialized companies that can take back your model and replace the defective parts. Buying asecond battery is also an interesting option. In this case, you should invest in a bag for transport or choose a so-called Range-Extender model. The latter is not very bulky and can be installed without constraint in the place of the water can.
Avoid cooling the electric bike battery
The cold impacts the working condition of your electric bicycle battery. The low temperature, even negative, tends to stress the components. In order to remedy this and increase its autonomy, take care to recharge it in a room where the ambient temperature oscillates between 10 and 25 °C. Do not put it in place until the last moment. You want to keep the battery warm? Simply use a neoprene blanket.
There is no specific time to recharge the electric bicycle battery. Once you notice a decrease in its capacity, proceed immediately to recharge. The principle is the same as for any device with a battery, such as a smartphone. Plug the power cable into an outlet and then connect the other end of the cord to the battery.
If you won't be using your electric bike for a long time, it's a good idea to remove the battery. Check the charge level and make sure it doesn't drop below 30%. Indeed, the accessory is at risk of self-discharge during this long storage time. Irreversible damage due to a chemical reaction can be felt and cannot be excluded.
Refer to the instructions available in the user manual of your electric bicycle battery. However, you can perform this step with ease. So start by unlocking the equipment via a special key. Pull it backwards or upwards using the handle. Note that when recharging, you do not have to remove the battery.
The procedure is quite simple. To get your electric bike battery back in good condition, whether it's lithium, NiMH or lead-acid, you can replace the worn components with new ones. To do this, perform a standard restoration of the defective components with a kit that has the potential to provide considerable longevity. Don't hesitate to test the battery intelligently if you want to determine its true capacity.
