What is a marine battery charger and how does it work?
A marine battery charger contains a more sophisticated internal circuitry than cheaper automotive types. Ultimately, it’s developed to be connected to the battery bank permanently.

What size marine battery charger do I need?
If you have a typical full-size auto battery, which is approximately 50 amp-hours, then you need to choose a 10 amp charger that would take about six hours to fully charge your battery if it was completely dead. For a detailed guide, check this out.
