Batteries of different types tolerate cold differently, so storing a motorhome or caravan over winter requires specific precautions. Before storage, all batteries should be fully charged, disconnected from the on-board network, and recharged every 6–8 weeks if needed. The starter battery is best removed and kept in a dry, frost-free room. Lithium (LiFePO4) batteries should be charged to 60–80% and fully switched off; charging below 0 °C is prohibited. Lead-acid and AGM batteries can freeze at 0…-3 °C when discharged, causing case rupture.
