What kind of battery does a wheelchair use？

Wheelchairs typically use deep-cycle batteries designed for consistent, long-lasting energy output. These batteries are commonly of two types:

1. Lead-Acid Batteries (Traditional Choice)

• Sealed Lead-Acid (SLA): Often used because of their affordability and reliability.
  • Absorbent Glass Mat (AGM): A type of SLA battery with better performance and safety.
  • Gel Batteries: SLA batteries with better vibration resistance and durability, suitable for uneven terrain.

2. Lithium-Ion Batteries (Modern Choice)

• LiFePO4 (Lithium Iron Phosphate):Often found in high-end or advanced electric wheelchairs.
  • Lightweight and compact.
  • Longer lifespan (up to 5 times the cycles of lead-acid batteries).
  • Fast charging and higher efficiency.
  • Safer, with a lower risk of overheating.

Choosing the Right Battery:

• Manual Wheelchairs: Usually don't require batteries unless motorized add-ons are included.
• Electric Wheelchairs: Commonly use 12V batteries connected in series (e.g., two 12V batteries for 24V systems).
• Mobility Scooters: Similar batteries to electric wheelchairs, often higher capacity for longer range.

If you need specific recommendations, consider LiFePO4 batteries for their modern advantages in weight, range, and durability.
