What is a leisure battery?
A leisure battery is the heart of your caravan, motorhome, or campervan's electrical system, which is used to power electrical appliances and equipment, like lights or a TV, in a motorhome or caravan.
As these appliances place higher power demands on a battery, motorhome leisure batteries are specifically designed to allow deeper discharge without affecting longevity.
How long do WattCycle motorhome leisure batteries last?
All WattCycle's batteries are deep cycle LiFePO4 batteries, so typically last up to 10 years or more. they all support 5000 - 15.000 cycles of life and are equipped with EV-grade A+ LiFePO4 cells. The long lifespan makes them your reliable RV power choice.
How to choose a leisure battery from WattCycle?
- Available physical space: Be sure to measure the usable area for the battery. Whether it's a caravan/RV battery compartment or the space under seats. You need to ensure the selected battery fits into this space.

- Battery-rated capacity: Battery capacity indicates how much energy the battery can store, measured in Ah (ampere-hours). Simply put, the higher the number, the longer the usage time between charges.
