How often do you change wheelchair batteries？

Wheelchair batteries typically need to be replaced every 1.5 to 3 years, depending on the following factors:

 Key Factors That Affect Battery Lifespan:

1. Type of Battery

   • Sealed Lead-Acid (SLA): Lasts about 1.5 to 2.5 years

   • Gel Cell: Around 2 to 3 years

   • Lithium-ion: Can last 3 to 5 years with proper care

2. Usage Frequency

   • Daily use and long-distance driving will shorten the battery's lifespan.

3. Charging Habits

   • Consistently charging after each use helps extend battery life.

   • Overcharging or letting batteries drain too low too often can reduce lifespan.

4. Storage & Temperature

   • Batteries degrade faster in extreme heat or cold.

   • Wheelchairs stored unused for long periods may also lose battery health.

 Signs It's Time to Replace the Battery:

• Wheelchair doesn’t hold a charge as long as before

• Takes longer to charge than usual

• Sudden power drops or sluggish movement

• Battery warning lights or error codes appear

Tips:

• Check battery health every 6 months.

• Follow the manufacturer’s recommended replacement schedule (often in the user manual).

• Keep a spare set of charged batteries if you rely on your wheelchair daily.
