Product Q&A

What size battery charger do I need for my lead acid battery I have in my camper?
A good battery charger rule of thumb for charging a lead acid battery, is using a charger with output current (amps) of 10-20% of the battery total stored capacity (Ah).
So, for example if the battery is 12V 100Ah, the charger need to be minimum of 10A and maximum of 20A. Often splitting the difference at 15% (so a 12V ~15A charger) is a good option. Happy charging!

Exactly what I needed. Review by Dennis IngramI needed a product that would limit a 14.2 V 165A alternator supply to 20A to charge two caravan batteries while driving so that the fridge would not drain the caravan battery when selected to DC while travelling long periods of time between 230VAC supplies.(Posted on 29 July 2019)
