Electric wheelchairs typically use the following types of batteries:
1. Sealed Lead Acid (SLA) Batteries:
- Gel Batteries:
- Contain a gelified electrolyte.
- Non-spillable and maintenance-free.
- Typically used for their reliability and safety.
- Absorbent Glass Mat (AGM) Batteries:
- Use a fiberglass mat to absorb the electrolyte.
- Non-spillable and maintenance-free.
- Known for their high discharge rate and deep cycle capabilities.
2. Lithium-ion (Li-ion) Batteries:
- Lightweight and have a higher energy density compared to SLA batteries.
- Longer lifespan and more cycles than SLA batteries.
- Require special handling and regulations, especially for air travel, due to safety concerns.
3. Nickel-Metal Hydride (NiMH) Batteries:
- Less common than SLA and Li-ion batteries.
- Higher energy density than SLA but lower than Li-ion.
- Considered more environmentally friendly than NiCd batteries (another type of rechargeable battery).
Each type has its own advantages and considerations in terms of weight, lifespan, cost, and maintenance requirements. When choosing a battery for an electric wheelchair, it’s essential to consider these factors along with compatibility with the wheelchair model.
