How to recharge a leisure battery

The leisure batteries are charged at a current equivalent to 0.1 times the capacity expressed in Ampere hours (Ah) for a maximum of 13 hours.

While 12 to 13 hours would normally be sufficient with a constant current charger, 15 hours may be necessary with a taper charger.

The exact duration of the recharge required will depend on the extent of the discharge that the battery has experienced. As an example a 50 Ah type RR1 battery that has been utilised for 3 hours for lighting a 100W lamp would have consumed 25 Ah and therefore must be charged at 5 Ampere for approximately 6 hours.
