Replacing Rv Coach Batteries

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.

Replacing rv coach batteries.

If you join two 6 volt rv batteries in parallel you will get 6 volts but the amps will now be increased. 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. Try to get batteries with high amp hour ratings. These are a combination of deep cycle and starting batteries.

The other kind of rv battery goes by many names the deep cycle battery the coach battery or the rv house battery. Batteries used in rvs are lead acid batteries which means they have several cells connected in series. Let s learn how to replace your rv batteries in only 7 steps. A parallel rv battery bank increases the current but allows the voltage to stay the same.

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. The batteries your rv came with are probably rv marine batteries. Each cell produces approximately 2 1 volts so a 12 volt battery with six cells in series produces an. Rv batteries in parallel.

Engine starting batteries won t last long if used in place of deep cycle batteries so this practice should be avoided. This is generally done by switching the main switch to off. Even if you think the rv batteries are dead hit the disconnect switch that disconnects the batteries from all dc equipment. 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.

Here are the simple 7 steps to replace rv batteries. But when the time came to replace them we decided to splurge on a set of lifeline agm absorbed glass mat batteries these are direct replacements for our original 6 volt flooded cell batteries but they re completely sealed accept a charge faster and perform better in every way.
