Electric Wheelchair Batteries
Electric wheelchair batteries are a crucial component of electric wheelchairs, providing the primary power source. There are 3 common types: lead-acid, AGM, and lithium-ion. Each offers distinct performance characteristics for daily use.
Most electric wheelchairs operate on a 12V battery, although some use 24V systems. Typical capacities range from 12Ah to 100Ah, depending on the wheelchair’s power requirements and desired range.
Due to their decreasing cost, lighter weight, and longer lifespan, lithium-ion batteries are becoming the preferred choice for electric wheelchairs. As a specialized manufacturer of lithium-ion batteries, we invite you to inquire about the best battery solution for your specific needs.
High stability
Electric wheelchair battery offers a long lifespan of 8-10 years and provide consistent power output.
Easy operation
Electric wheelchairs are designed for easy operation, often requiring only one person to maneuver.
Portability
Lithium batteries are compact and lightweight, making them easy to transport and carry.
Safety
Deep-cycle lithium batteries ensure long-term safe and reliable operation.
battery for electric wheelchair product
12V deep-cycle batteries are designed for long-lasting, steady power output, making them ideal for applications requiring sustained discharge. They typically offer a cycle life of over 6000 cycles and can handle high current demands.
Some electric wheelchairs and scooters use multiple 12V batteries connected in series to provide a 24V output. This configuration can accommodate larger motors and improve overall system reliability.
Connecting two 12V batteries in parallel increases the overall capacity while maintaining the voltage, resulting in longer operating times.

Electric wheelchair battery replacement
When you consider to replace lead acid battery to lithium, please consider following aspects:
Compatibility: Ensure the replacement battery matches the electric wheelchair’s voltage, capacity, and dimensions. Most electric wheelchairs use 12V “deep-cycle” batteries, designed for sustained discharge rather than short bursts of power.
Common replacement battery types:
- Lead-acid batteries: Affordable but require regular maintenance, such as adding distilled water.
- AGM and gel batteries: Sealed, maintenance-free, suitable for air travel, but more expensive.
Installation and maintenance:
- Battery installation often requires technical consultation to ensure safety.
- Always ensure the wheelchair is off and unoccupied when replacing batteries.
- Regularly check the battery’s charge status and voltage to maintain optimal performance. Following these steps ensures a safe and efficient battery replacement, extending the wheelchair’s lifespan and improving the user’s quality of life.

Electric wheelchair battery charger
An electric wheelchair battery charger is a crucial component that ensures the smooth operation of an electric wheelchair. Below is an overview of electric wheelchair battery chargers:
Charger Functions
- Safe Charging: Electric wheelchair chargers are equipped with multiple protective circuit functions to ensure safe and rapid battery charging, optimizing the performance of the electric wheelchair.
- Indicator Lights: Most chargers are equipped with indicator lights. A red light typically indicates that the battery is charging, while a green light indicates that charging is complete.
Usage Precautions
- Initial Use: Before using a new battery for the first time, it should be fully charged to ensure optimal performance.
- Charging Environment: Charging should be carried out in a well-ventilated, dry environment. No objects should cover the charger or battery.
- Charging Time: Typically, charging time is 5-10 hours. Once fully charged, disconnect the charger promptly and avoid leaving it connected for extended periods.
- Dedicated Charger: Use only the dedicated charger provided with the wheelchair. Using other chargers may damage the battery.

- User weight and wheelchair load: Heavier loads increase battery consumption and shorten lifespan.
- Terrain: Flat terrain places less strain on the battery, while uneven terrain accelerates battery consumption.
- Temperature: Extreme temperatures accelerate battery chemical aging. It is recommended to store batteries in a temperature-controlled environment.
FAQs for batteries for electric wheelchair
Lithium iron phosphate batteries are the optimal choice for electric wheelchairs due to their long cycle life of 6000+ cycles, lighter weight, rapid charging capability (1-2 hours), and maintenance-free operation.
Yes, it is possible. A dedicated charger should be used to charge the battery. Before installation, it's best to measure the battery's output to ensure it's functioning normally and can be restored to full operation.
It is not recommended to use car batteries in electric wheelchairs. Car batteries are designed differently from wheelchair batteries and may not provide the appropriate voltage and capacity for wheelchair use. This could negatively impact the wheelchair's performance and safety.
