Group 31 Marine Leisure battery replacement.
High capacity Group 31 leisure batteries, perfect for boats, caravans, motor homes and off-grid living, delivering dependable 12V energy for onboard systems.
For marine and leisure use, the Group 31 battery is a trusted choice thanks to its high capacity and deep-cycle capability. With dimensions of roughly 330mm x 173mm x 240mm and a capacity range of 95–125Ah, it provides ample energy to run onboard systems, lighting, pumps, navigation electronics, and appliances for long durations.
Unlike a standard car starter battery, which delivers a short burst of energy, a leisure battery is specifically built to discharge gradually and recharge repeatedly without significant loss of performance. This makes it especially suited to life on the water or off-grid travel in caravans, motor homes and campervans. The Group 31 marine/leisure battery is also vibration-resistant and designed for stability, ensuring it can handle the movement of a boat or vehicle without issue.

A leisure battery is different from a standard starter battery because it’s made to provide continuous power over long periods, rather than a short, intense burst to start an engine. Where a car battery delivers high current for just a few seconds, a leisure battery is designed for deep-cycle use, meaning it can be charged and discharged repeatedly without losing performance, while still offering the capability to start an engine if required.
