Replacing rv coach batteries.

Try to get batteries with high amp hour ratings. This is generally done by switching the main switch to off. 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. A parallel rv battery bank increases the current but allows the voltage to stay the same.

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. Here are the simple 7 steps to replace rv batteries. You will probably want to replace them with true deep cycle batteries as they can be drawn down and recharged over and over again. These are a combination of deep cycle and starting batteries.

Even if you think the rv batteries are dead hit the disconnect switch that disconnects the batteries from all dc equipment. Engine starting batteries won t last long if used in place of deep cycle batteries so this practice should be avoided. If you join two 6 volt rv batteries in parallel you will get 6 volts but the amps will now be increased. Batteries used in rvs are lead acid batteries which means they have several cells connected in series.

Batteries used to power the coach in an rv must be a deep cycle design to withstand the frequent and deep discharges and recharging they typically receive. To properly maintain and extend the life of your rv batteries you need to have a basic understanding of what a battery is and how it works. Let s learn how to replace your rv batteries in only 7 steps. Regular care and maintenance kept our original batteries in good condition for 6 years.

The batteries your rv came with are probably rv marine batteries. Parallel connections are done by connecting two positive terminals to two negative terminals.
