Product Details

The battery maintainer is a charging device that enables an extra battery bank to be kept 'topped up' from the main battery bank which has the charging device(s) connected to it (e.g. alternator, battery charger, solar cell / wind turbine etc).

The unit transfers approximately 3A(12V) and requires
the charging devices to be turned on to work.

It is best suited at keeping a starter battery topped up and maintained by the charge that your house bank receives. 

How does it work?
The unit is activated when the main battery has reached around 13.3V and allows excess power to be transferred from the primary charging system to charge / maintain an auxiliary battery bank.

The transfer current is 3Aat 12V
