How long does an electric wheelchair battery last?

2-4 years with daily use; GEL delivers 600-800 cycles at 50% depth of discharge before significant capacity loss.

GEL or AGM — which should I choose for my wheelchair?

GEL is more stable and charger-friendly; deep cycle AGM gives more Ah per kilo, better cold performance and lower cost per cycle. Both are sealed, maintenance-free and off-gas free.

Can I replace just one battery in the 24 V bank?

No. Both batteries in a series bank must be identical (same brand, model and date); mixing a new one with a used one unbalances the system and shortens the life of both.

What range do these batteries give?

25-50 km per charge, depending on chair type, user weight and terrain.

Are they compatible with my Invacare, Permobil or Sunrise Medical wheelchair?

Yes, as long as you match the capacity (Ah) and physical dimensions of your chair's original bank.
