Preventbattery discharge - with pure solar energy!
Gives back to the battery what it gradually loses! Especially during long periods of standing or very cold weather, batteries give off more and more power.
This is now a thing of the past! simply connect the solar panel to the cigarette lighter and place it in the sun (e.g. on the shelf). A gentle charging current keeps your battery "in good spirits" from now on.
Optionally, the solar protection can also be connected directly to the battery. For all 12 V batteries - also in trucks, caravans, caravans or boats.
Not suitable for charging empty batteries.
