All You Need to Know About Buying Car Battery Chargers for RV
Frequently Asked Questions (FAQs)
The most effective method for charging RV batteries from a remote location or at home is to utilize the shore power cord connected to a 120-volt electrical outlet (such as a shore power pedestal or wall outlet).
It is advisable to employ a DC to DC charger, which helps protect and extend the lifespan of your RV battery while preventing overloading of the vehicle’s alternator. Most DC to DC charger models incorporate the same three-stage charging modes found in all chargers, ensuring safe battery charging and preventing alternator damage.
Batteries should not be charged at an amperage rate exceeding 20 percent of their Amp-hour (A-h) capacity per hour. For instance, a 200-A-h battery should not be charged at more than 40 amps, and the charging rate must be reduced if the battery becomes excessively hot or begins to expel electrolyte.
The same principle applies to a trickle charge on an RV battery. This type of charge is ideal for lead-acid batteries that will be in an idle state for an extended period, as they gradually lose their charge. A trickle charge will slowly replenish the battery’s charge.
