Replacing rv coach batteries.

Even if you think the rv batteries are dead hit the disconnect switch that disconnects the batteries from all dc equipment. While the chassis batteries start your rv s engine it s the house batteries that power the interior lights vent fans water pump and other 12 volt.

If you join two 6 volt rv batteries in parallel you will get 6 volts but the amps will now be increased. The batteries your rv came with are probably rv marine batteries.

Try to get batteries with high amp hour ratings. This is generally done by switching the main switch to off. You will probably want to replace them with true deep cycle batteries as they can be drawn down and recharged over and over again. Batteries used in rvs are lead acid batteries which means they have several cells connected in series.

Each cell produces approximately 2 1 volts so a 12 volt battery with six cells in series produces an. Rv house batteries expel less energy measured in amps at once but must last for a longer period of time as they re responsible for routing electricity to an rv s cabin.
