How many batteries does an electric wheelchair have？

Most electric wheelchairs use two batteries wired in series or parallel, depending on the wheelchair's voltage requirements. Here's a breakdown:

Battery Configuration

1. Voltage:
   • Electric wheelchairs typically operate on 24 volts.
   • Since most wheelchair batteries are 12-volt, two are connected in series to provide the required 24 volts.
2. Capacity:
   • The capacity (measured in ampere-hours, or Ah) varies depending on the wheelchair model and usage needs. Common capacities range from 35Ah to 75Ah per battery.

Types of Batteries Used

Electric wheelchairs typically use sealed lead-acid (SLA) or lithium-ion (Li-ion) batteries. The most common types include:

• Absorbent Glass Mat (AGM): Maintenance-free and reliable.
• Gel Batteries: More durable in deep-cycle applications, with better longevity.
• Lithium-ion Batteries: Lightweight and longer-lasting but more expensive.

Charging and Maintenance

• Both batteries need to be charged together, as they function as a pair.
• Ensure your charger matches the battery type (AGM, gel, or lithium-ion) for optimal performance.
