Will it fit? Match your old battery on four things: voltage (12V), capacity (35Ah), size (197 × 131 × 180 mm (7.76 × 5.16 × 7.09 in)) and terminal (L-terminal (bolt)). Mobility scooters and powerchairs run two 12V batteries wired in series (a 24V system), so replace both at the same time with a matching pair for balanced performance and the longest life. Not sure? Send us your scooter or powerchair make and model and we will confirm the right battery before you order.
Fast UK dispatch. Order before 12pm on a working day for next-working-day dispatch. Delivery is calculated at checkout — sealed lead-acid batteries are heavy items, so a small carriage charge may apply.
