Keep your leisure or vehicle battery healthy through the off-season with the Solar Technology 8W Fold-Up Solar Battery Maintainer. Its twin crystalline panels deliver a steady trickle charge to counter the slow drain from alarms, trackers and on-board electronics, so your caravan, motorhome, campervan, car or boat is ready to go when you are.

Unfold the panel and fix it inside the windscreen with the suction cups, or lay it outside facing the sun. Then connect it directly to the battery with the crocodile clips or plug it into a live 12V socket. A built-in blocking diode stops the battery discharging back through the panel at night, and no separate charge controller is needed for batteries of 60Ah or larger.

Folded, it measures 230 x 198 x 15mm, small enough to keep in the glovebox, and a pocket on the back stores the cable.

Please note: this model is for 12V batteries of 60Ah or more. For smaller batteries, such as motorcycles, mowers or small boats, choose a regulated maintainer kit.
