Details
A sealed, maintenance-free 12 V battery designed for mid to large mobility scooters that accept 50 Ah batteries. It uses AGM construction for reliable, low-maintenance power. The battery is suitable for float or cycle use and features F8 terminals for common scooter connections. For best results, charge fully before first use and consider replacing both batteries together to keep performance balanced.
Key benefits

- Reliable starting and run time – 50 Ah capacity offers steady power for mid to larger scooters.
- Low self-discharge – holds charge better during storage, helping when the scooter is used less often.
- Simple fit – common F8 terminals make replacement straightforward for most scooters.
- Safer handling – sealed construction cuts down on fumes and acid exposure.
Who is this for?

Product details
This is a 12 V, 50 Ah sealed lead-acid Mobility Scooter Battery using Absorbed Glass Mat (AGM) technology. The sealed, maintenance-free construction removes the need for periodic watering and reduces the risk of corrosive acid spills or fumes, making it easier and safer to handle at home.
The battery is built with lead-calcium tank-formed plates for consistent output and is suitable for both float and cycle use. Its low self-discharge behaviour helps when the scooter is stored for short periods, so it keeps a charge better than older-style batteries.
Connections use F8 terminals, which are commonly used on mid to large mobility scooters and help simplify installation. The compact case and dimensions mean it fits into many standard battery compartments, but always check the space and terminal orientation before purchase.
For reliable performance, charge the new battery fully before first use and keep to a regular charging routine. Batteries of different ages perform differently, so it is sensible to consider replacing both scooter batteries at the same time to keep output balanced and avoid uneven wear.
