Group-24-Marine Leisure deep cycle battery replacement

Group 24 Marine Leisure batteries built for deep cycling, powering caravans, motor homes, boats and off-grid appliances with steady 12V energy.

When talking about batteries, Group sizes make it easy to know exactly what will fit. A Group 24 battery has a standard footprint of 259mm x 169mm x 208mm (the height can vary depending on the terminals). This size is widely used across the leisure, marine and automotive sectors, so it’s important to match the group number when replacing an existing unit.

A leisure battery is different from a standard starter battery because it’s designed to provide a steady flow of power over a long period, rather than a short burst of energy to crank an engine. Where a car battery delivers high amps for a few seconds, a leisure battery is built for deep cycling—charging and discharging repeatedly—without losing performance and still being able to perform the job of a starter.

• Group 24 AGM leisure battery

This AGM leisure battery is completely sealed and requires no topping up, making it a practical and hassle-free power source. The gel technology locks the electrolyte in a stable form, so there’s no risk of spillage, even if the battery is moved or tilted. It delivers steady power over long periods, withstands regular deep discharges, and performs reliably in situations where vibration or rough terrain would quickly wear down a standard battery.

Because of these qualities, Group 24 AGM leisure batteries are a popular choice for campervans, caravans, motor homes, boats, yachts and off-grid setups.
