Solar battery maintainer

OSRAM OSP500 BATTERYcharge SOLAR 5 W Solar Battery Maintainer for 12 V Batteries

Keeps your battery topped up with sunlight while the vehicle sits unused.

The OSRAM OSP500 BATTERYcharge SOLAR 5 W is a solar battery maintainer that keeps a 12 V battery charged without mains power. It connects via battery clips or a 12 V DC power plug and keeps working on overcast days. Ideal for cars, motorcycles, caravans, vans and small trucks used only seasonally.

Stops slow drain on a parked vehicle

Alarms, immobilisers and lock monitoring keep drawing current even with the ignition off. The OSRAM OSP500 offsets that constant drain with solar power, so the battery is ready to start after a long standstill.

Monocrystalline cells delivering up to 5 W

The monocrystalline solar cells of the OSP500 convert sunlight more effectively than traditional panels for faster charging. The panel still produces power in overcast conditions, making it usable all year round.

IP65 rating for outdoor placement

IP65 water resistance lets you place the panel outside the vehicle and aim it at the sun for the best yield. The 3 m power cable reaches the battery while the panel stays in the sunniest spot.
