Service life depends on the number of charging cycles, maintenance and cell quality. Generally speaking, it takes 3 to 5 years before you notice a real loss of autonomy, but the most carefully maintained cells can last longer.
How much does an electric bike battery cost? Prices and advice
Are you wondering how much you'll have to pay for a new EAB battery if you need to replace it? It's true that the purchase price of a battery remains a crucial point for any electric bike owner or future buyer, because if you use your bike intensively to get to work every day, for example, you might want to replace it after a few years. Or you may wish to have two batteries so you never run out, and simply replace the battery without having to immobilize your two-wheeler.
In 2025, the offer is varied, and replacement batteries can be found at all prices. Between new batteries, second-hand batteries and reconditioned options, it can sometimes be confusing.
In this article, we'll delve into the details: price trends, factors influencing prices, key points for making the right choice, not forgetting tips for prolonging the life of your VAE battery.
Electric bike battery prices in 2025: what to expect?
In recent years, the market for electric bikes has exploded, leading to a rapid evolution in battery technologies. By 2025, Lithium-ion and Lithium-polymer (LiPo) models will largely dominate, thanks to their performance and light weight. Brands such as Bosch, Shimano, Yamaha, Panasonic, LG Chem and Samsung SDI now offer diversified ranges to meet every need.
What are the average prices by range and capacity?
The price of a battery often depends on its capacity in Wh (watt-hours). The higher the capacity, the greater the autonomy... and the higher the bill. Here are a few benchmarks:
- 200 Wh to 300 Wh: more entry-level, ideal for short urban trips. Prices start at around €200 to €300 for mid-range models.
- 400 Wh to 500 Wh: the majority of today's electric bikes are based on this capacity range, offering comfortable range. Expect to pay between €400 and €700 on average.
- 750 Wh to 1000 Wh: top-of-the-range, for long rides or sustained journeys. Prices here can climb to over €900, or even more than €1,200, depending on the brand.
Of course, these ranges vary according to battery technology (lithium-ion vs. lithium-polymer), brand reputation and whether or not a compatible charger is available.
new vs. used prices: what's the difference and what are the risks?
It can be tempting to buy a used battery to save money. Prices can be 30% to 50% lower than new, especially for an old battery removed from a VAE.
However, the big unknown remains the state of the internal cells. Batteries are actually an assembly of several small units, often in 18650 (cylindrical) or prismatic (rectangular) format. 18650s are widespread and relatively easy to recondition. Prismatic batteries, on the other hand, are less standard and can complicate the repair or replacement of worn cells.
If these cells have already undergone numerous charge cycles, or if their charge level no longer exceeds 80%, the battery's autonomy will be less than that of a new battery. The risk? Investing in a battery pack that will give up on you sooner than expected, with its lifespan already begun. If you don't want to take that risk, visit our shop's electric bike battery section.
Factors influencing the price of an electric bike battery
Brand and reputation: A Bosch or Shimano battery is generally more expensive than a generic one. Reputable manufacturers often guarantee better reliability and more responsive after-sales service.
Technology: Lithium-ion batteries, which are lighter and more durable, dominate the EAB market despite their higher cost.
Capacity and power rating: a 500 Wh battery will have a higher purchase price than a 300 Wh model, especially if the brand also offers advanced features (connectivity, precise charge level indicator, etc.).
Engine compatibility: Some batteries are specific to particular engine systems (Bosch, Yamaha, etc.). This can push up the price, as you won't necessarily be able to opt for compatible batteries from another manufacturer.
Warranty and safety standards: Products with CE certification, meeting UN38.3 standards or complying with the European battery directive may be more expensive, but are often more reliable. Normally, you can't get batteries that don't meet these standards in France, but if you're ordering from a site outside the EU, it's not a bad idea to check certifications.
Where to buy an electric bike battery at the best price?
There are many ways to find the right battery:
Specialty stores: personal advice, help in choosing the right battery or battery charger. Prices may be a little higher, but the warranty is often solid.
E-commerce sites: This is the realm of comparisons. You can scour customer reviews, see different battery brands and pick up interesting special offers. Beware, however, of fake or counterfeit reviews.
Repair shops: Some mechanics or bicycle specialists offer new, used or reconditioned batteries. The advantage: they can assess motor compatibility and steer you towards a compatible charger.

How to choose the ideal battery for your electric bike?
Finding the best battery isn't just a question of price. You'll need to select the right one for your needs, your type of trip and your bike.
Evaluate your needs: range, power and type of trip
If you're content with short trips around town, a 300 Wh or 400 Wh pack may suffice. Batteries compatible with urban use focus above all on lightness and rapid recharging. On the other hand, for longer rides or cycle touring, aim for 500 Wh or even 750 Wh.
new, used or refurbished : which is best for your budget?
- new Ideal if you're looking for peace of mind (manufacturer's warranty, original battery, battery charger included). The cost remains higher.
- Second-hand: Interesting if you're on a budget and find an honest seller. Check the maximum possible charge level and the number of charge cycles already completed.
- refurbished A compromise between new and used. Worn cells are replaced, giving the battery a second life. Want to find out more? Read our article on electric bike battery reconditioning.
Check compatibility with your motor and bike
Not all motor systems require the same voltage or discharge current. A Bosch battery will not necessarily be compatible with a Shimano or Yamaha motor, unless they are specially designed to be interchangeable. Before buying, always check the manufacturer's recommendations or ask a professional for advice.
Safety certifications and standards to know before you buy
In Europe, CE certification is a guarantee of conformity. The UN38.3 standard certifies that the battery has passed a series of safety tests (temperature, pressure, etc.). The European directive on batteries also defines recycling and traceability rules. Beware of dubious batteries with no label or guarantee.
Can an electric bicycle battery be repaired or reconditioned?
If your old battery loses autonomy or stops working, reconditioning can be an excellent solution. Here's how it works: you replace the faulty cells with new ones of equivalent characteristics (often 18650 or prismatic cells). This gives the battery a new lease of life, while reducing waste.
This is a more affordable option than buying a new battery, especially for high-end battery brands. However, it is essential to call in a specialist. Opening the battery yourself, without knowledge or appropriate equipment, can be dangerous.

Tips for extending battery life
Properly maintaining your EAB battery means greater reliability and long-term savings. Here are a few recommendations:
- Avoid deep discharges: Ideally, recharge before the charge level drops to 10%. Excessive discharging wears out cells faster.
- Choose moderate temperatures: not too hot, not too cold. Avoid leaving the battery in direct sunlight or in an icy garage.
- Use a compatible charger: An unsuitable battery charger may regulate voltage or current incorrectly. This can lead to premature wear and tear, or even overheating.
- Store at half-charge: If you won't be using your electric bike for several weeks, leave the battery at around 50-60% charge.
- Handle with care: Avoid shocks and moisture. A cracked or damaged battery can become dangerous.
