This Top-Up Charger was designed for use in motor homes, canal boats etc fitted with either solar or mains charging systems. It transfers charge from the leisure battery to the engine battery.

If whilst the leisure battery is being charged it reaches a voltage 0.4V greater than the engine battery, then the Top-Up Charger transfers charge from the leisure battery to the engine battery until the voltage difference is 0.2V, it then terminates the transfer.

If the engine battery has a constant drain such as Security Systems, Clocks, Hi-Fi Equipment, etc and its voltage drops 0.4V below the leisure battery, then the Top-Up Charger will transfer charge from the leisure battery to the engine battery.

The Top-Up Charger is able to cope with a discharge of up to 1A and will limit the transfer to protect itself.

The LED Charge indicator shows four charge states:-
1. OFF:             
2: ON “Bright”:
