We recommend driving the vehicle for at least one hour every week to charge both the van battery and the leisure battery, and that you hook the vehicle up to mains electrics overnight at least once a month dependant upon usage. This will ensure the battery has a good charge and is conditioned.

We would also recommend that you make sure everything is turned off when not in use, especially the fridge, and that you have the fridge set on a medium to low setting whenever not hooked up if possible, as the fridge is the largest draw of power from the leisure battery. The fridge should also show ‘VENT’ on the door catch when NOT in use. When in use, that catch should be switched to a blank side to ensure the cold air is kept in the fridge.

Dependant on how the battery has been conditioned, how charged it is, the ambient outside temperature, and what you are using within the conversion, such as fridge/freezer, heater, 12v. sockets etc, we would expect anywhere from 12 hours to 48 hours usage as a general rule. However, dependant on the demand, this can increase or decrease.

Continuous use of the leisure battery without charging by mains hook up will drain the leisure battery to the point it will no longer hold a charge, and keeping the battery on mains hook up when the conversion is not in use can also cause damage to the leisure battery and in both instances would result in the battery requiring replacement.

After every use of the leisure battery we advise to hook up to mains to fully recharge and condition the batteries, this will stop the batteries from being fully discharged and causing damage to the battery cells which in turn will reduce the battery health.
