Designed to trickle charge 12v lead-acid batteries with no additional running costs. This charger only requires daylight to work, even if the weather is overcast or dull. Ideal for cars that will be left standing for long periods, as well as maintaining batteries in caravans and boats. The built-in blocking diode prevents reverse charging from the battery to the solar panel at night and the flashing blue LED light indicates when charging is in progress.
