Battery chargers

Stabilize your electrical system with a complete solution

Voltage, power, and battery type must match to keep your system stable.

The sizing of cables and fuses is also important for safe and efficient operation.

This ensures your on-board electrics run reliably – from start to anchorage.

Discover variants, materials, and designs built for marine use. This way, you'll find equipment that remains reliable on board – season after season.

Deine Fragen / Unsere Antworte

What charging current do I need for my house battery?
As a rule of thumb, about one-tenth of the nominal capacity in amperes applies – so a 100 Ah battery charges well with around 10 A. Too much current damages the battery, too little unnecessarily prolongs the charging time and rarely achieves full capacity.
Can I use a normal car charger on a boat?
This is possible in the short term, but car chargers are usually not splash-proof and often do not offer a multi-circuit function for starter and service batteries. Marine chargers are designed for the specific requirements on board and are the safer choice in the long run.
Do I have to set the charging profile to my battery type?
Yes, absolutely. AGM, gel, and lithium batteries tolerate different charging voltages and curves than wet lead-acid batteries. An incorrect profile can lead to overcharging, loss of capacity, or, in the worst case, a defect.
Can I leave the charger connected permanently, even over the winter?
This works well if the device has a true maintenance or winter mode. It then keeps the battery charged at a low voltage without overcharging it. Make sure that the shore power connection at the jetty is designed for continuous operation.
