At present, electric wheelchairs have become ubiquitous in our lives. The old or the disabled travel in daily life and they choose the low-speed electric wheelchairs as the daily transportation. However, people are confused about how to choose suitable electric wheelchair batteries. Whether you are a user or an electric wheelchair wholesaler, we are happy to provide you with the information you need to make an informed decision.
Electric Wheelchair Battery Types
The most popular electric wheelchair battery types are lead acid and lithium. We’ll share information about the difference between lead-acid batteries and lithium batteries for electric wheelchairs with the same battery capacity.
- Price: The price of lead acid batteries is cheaper than lithium batteries.
- Weight: The weight of lead-acid batteries is about four times as much as lithium batteries.
- Mileage: The lithium batteries for a wheelchair have longer mileages than lead acid batteries for a wheelchair.
- Wheelchair battery life: The lead acid wheelchair battery life is about 2-3 years and 4-5 years for the lithium wheelchair battery life.
2024 Trending: Wheelchair Lithium Batteries
The lifepo4 battery is one of the most popular 2024 trending wheelchair lithium batteries. Because lifepo4 batteries have a more stable work environment and life cycles. The specification 24V lithium wheelchair battery is the best hot sale because more wheelchairs choose a lifepo4 battery instead of a 24V lead acid battery. But if the wheelchair supplier or manufacturer would like to choose the lighter lifepo4 battery. The customized lifepo4 battery pack seems more popular.
The lifepo4 cells, made of the lifepo4 battery pack for wheelchair, are recommended as below:
- LiFePO4 18650 cell
- LiFePO4 26650 cell
- LiFePO4 32700 cell
Advantages of LiFePO4 24V Wheelchair Batteries
- Long lifecycles: 3000-4000 cycles
- The warranty time: 2 years
- More safety
- Thermostability
- Lighter weight compared to lead acid batteries
Most electric wheelchair manufacturer prefer to choose to design their brand-compliant housing to increase their sales and market shares.
To design one more intelligent electric wheelchair battery, the cost and market expectation estimation should be considered before you start designing the battery housing.
Wheelchair Battery Charger Knowledge
Each wheelchair battery should be matched with the dedicated charger to ensure safety and battery performance.
The different materials batteries have different charge voltage platforms. The regular 12V and 24V lithium wheelchair batteries are as below:
| 12.6V Li-ion Battery | Specification | Charger | Full Charge Voltage |
| LiFePO4 | 12.8V LiFePO4 Battery | 14.4V LiFePO4 charger | 14.4V |
| LiFePO4 | 25.6V LiFePO4 Battery | 28.8V LiFePO4 charger | 28.8V |
| Ternary | 11.1V Ternary Battery | 29.4V Li-ion Battery | 12.6V |
| Ternary | 25.9V Ternary Battery | 29.4V Li ion Battery | 29.4V |
Guidance: Ensuring Wheelchair Battery Safety
Wheelchair batteries have more safety and quality control. You should evaluate the wheelchair batteries’ safety from the design to the manufacturing.
When you start to design your wheelchair, you should consider the battery pack design first. If you do not consider it in advance, you suffer the risk and difficulty when the wheelchair batteries enter the market. The cell brands and cell model specifications are crucial for battery safety. You will experience making the prototypes and modifying the workcraft on the bulk production. During this process, some risks will be reduced. The wheelchair batteries should comply with ISO9001:2015 quality management standards. Furthermore, since wheelchair lithium batteries are used on aircraft, each battery must be packaged in UN cartons.
