When you’re planning a motorhome adventure, a reliable motorhome leisure battery is non-negotiable. It powers your lights, fridge, and more, but picking the right one—like a lithium leisure battery or AGM leisure battery—can feel overwhelming.

Most motorhomes use a 12V leisure battery, but your choice hinges on travel habits and budget. This guide walks you through the essentials: calculating power needs, comparing types, and ensuring a perfect fit.
