One of the most important RV battery maintenance tips involves checking the fluid levels of each of the batteries on your unit.

      Hi Kathy. Thank you for visiting the RV Repair Club site and the opportunity to assist with your battery issue. Improper battery storage and charging is the leading culprit to lead acid batteries going bad and not being able to store a charge. If they are not subjected to a multistage charge every month, they will sulfate and loose capacity. This can only be accomplished by a multistage charger or large inverter. Leaving them plugged in with a typical RV converter does not work. Even though your batteries are only one year old, they are probably sulfated and that is why you are only getting about 10 minutes when the power goes off? My advice, buy a Battery Minder from Northern Tool which sends high impact waves into the battery and breaks up the sulfation without the gassing and will extend the life of your batteries by over 200 cycles.

    hello, during the winter months I turn off the disconnect off to the battery on our 5th wheel and hook up a battery tender, is this a god idea or not? I have heard both ways.

      Hi, Tim. Thank you for visiting the RV Repair Club site and the opportunity to assist with your battery storage question. The Battery Tender is simply a 2 amp trickle charge that will keep the batteries topped off and prevent them from freezing, however your batteries will still sulfate in this condition and weaken. It is best to install a Battery Minder which will condition the batteries as well as keep them charged and they will last much longer. You can get a Battery Minder at Northern Tool.
