A leisure battery powers the 12V electrical system in a campervan, caravan, or motorhome. It can run a range of onboard appliances designed to operate on 12V power.
Common appliances powered by a leisure battery include:
- LED lighting
- Water pumps
- 12V compressor fridges
- Diesel or gas heaters
- USB charging points
- 12V televisions
- Control panels and ventilation fans
The amount of equipment you can run and for how long, depends on battery capacity (Ah), usable energy, and the power consumption of your appliances.
For example, low-power items like LED lighting or USB charging use very little energy, while appliances such as fridges, heaters, or inverters will drain the battery more quickly.
Important
Leisure batteries provide 12V DC power, so appliances must either be designed for 12V use or powered through a 240V inverter if they require mains electricity.
Choosing the right battery capacity and charging setup helps ensure you have enough power for your appliances while spending time off-grid.
