Understanding the different types of batteries for electric bikes
Electric bike batteries are the beating heart of your ride. From old-fashioned lead-acid batteries to state-of-the-art lithium-ion technologies, understanding your battery is essential to riding longer and maintaining your bike properly.
Batteries are the secret ingredient in all electric vehicles, from bicycles to cars. Often the most expensive and technologically advanced part, they largely determine performance and price. This article introduces you to the different types of batteries for electric bikes and how to look after them.
Electric bicycle battery basics
Battery types for electric bikes
Lead-acid batteries
Old technology, inexpensive and robust, but heavy and inefficient. Their dangerous storage and noxious fumes have made them obsolete.
Nickel-Metal Hydride (NiMH) batteries
More efficient than lead-acid batteries, they are safer and last longer, but remain heavy and sensitive to heat.
Lithium-ion (Li-ion) batteries
This is the current standard. Light, powerful and durable (500-1,000 cycles, even 2,000 with certain technologies). Perfect for long distances.
Beware, however, of low-end models, which can present risks.
Lithium Iron Phosphate (LiFePO4) batteries
Very safe and durable, but too bulky for electric bikes. They are more common in other vehicles.
Battery care and maintenance
- Avoid extreme temperatures.
- Maintain a load level between 30-50% in storage.
- Use the original charger.
- Store in a cool, dry place (13-24°C).
- Inspect connectors regularly.

Key points
- Lithium-ion batteries are the benchmark for electric bikes, thanks to their light weight, high capacity and long-lasting performance.
- Battery life depends on factors such as use, terrain, temperature and maintenance - good maintenance can extend battery life by up to 10 years.
- Safe handling and storage, avoiding overcharging and extreme temperatures in particular, considerably improve battery safety and reliability.
Frequently asked questions
What is the best type of battery for an electric bike?
Should I remove the battery when I'm not driving?
Short-term: no. For long-term storage: yes, and keep at room temperature.
What is the average life of a bicycle battery?
Around 500 to 1,000 cycles. This is equivalent to several years, even 10 years with good care.
How can I extend the life of my battery?
Avoid heat, do not charge to 100%, use the right charger and store in a dry place.
