Awaiting new stock.

This 3-stage battery charger from UK manufacturer Rovert Electrical will keep your wet lead-acid deep-cycle leisure battery in prime condition and prolong its life whilst connected to mains power on-site or at home. It offers fully automatic charging so you can leave it connected without damaging your battery.  An additional feature of this charger is that it can be used as a Power Supply Unit (PSU) to directly power 12V appliances whilst connected to mains and it has in-built protection against short-circuit, over-current and thermal overload. There is an output to connect a remote LED to indicate charging status and the case has 4 holes for mounting to a flat surface(horizontal or vertical mounting).

Please note: Battery connection leads are not included but we recommend using 4mm² thin wall cable 6.3mm fully insulated female blade terminals to connect to the charger. This unit is not fitted with a 3-pin plug as it is intended to be hard-wired into a consumer unit, but one can be used if required.

Recommended for wet lead-acid leisure batteries with a capacity in the range of 130 - 200Ah.

Delivered promptly and all as described. Bought to replace a non fan assisted 12 amp charger which burnt out. Particularly like the remote LED as twice in my life chargers have packed up running down the batteries while the mains LED is showing but of course no charge. Only reservation is a slight hum. Just hope it lasts.
