This product is suitable for charging 12 V Sealed Lead-Acid (SLA) batteries
including Valve-Regulated Lead-Acid (VRLA) batteries, both Absorbed Glass Mat
(AGM) and Gel batteries.
Storage
If the caravan is to be stored for a long period of time, first fully charge the battery
and ensure all loads are disconnected. Recharge the battery at least once every
6 months. Regular recharging will prevent the battery from becoming deeply
discharged—a condition which can significantly shorten battery life.
Deeply Discharged Batteries
This battery charger is not designed to charge deeply discharged batteries. Its
effectiveness in charging such a battery is a function of the depth of discharge
and the battery size. Bigger (higher capacity) batteries will be more troublesome
in this respect.
In normal use a battery connected to the Genius-II should never become deeply
discharged, so recharging it should never be a problem.
If a battery has become deeply discharged and the Genius-II will not charge it,
remove the battery (see Battery Connection/Disconnection Procedure on
page 12) and charge it with a stand-alone charger. Once the battery voltage has
recovered to normal levels and the charge current is less than 15 A, it may be
reinstalled.
