RV Battery Maintenance Tips
RV Batteries and Care
The house batteries provide the heartbeat that keeps all the 12-volt direct current systems alive. Each new RV (motorhome, 5th wheel or travel trailer) comes with a standard installation of one or more deep cycle house batteries to provide adequate circuit power for most uses.
There is usually room to expand or upgrade 12 volt power for the many RV owners that like to test the boundaries of their RV capabilities. If you are among those RV-ers that always camp at a full-service campsite with plenty of shore power to keep the house battery charged then you may not need to do anything. But if you dry-camp, rough it, use your RV a lot, never have enough power for jacks, slide-outs, and awnings, or plan to use your RV in this way, then maybe you should consider upgrading or expanding your house batteries.
Not all batteries are created equal. HD-24 deep cycle batteries may be adequate for small travel trailers but I recently instructed my technicians to install HD-27 batteries in all 5th wheels that have electronic leveling systems or hydraulic slide-outs. The difference is more amp-hours which equals the ability to energize 12-volt circuits longer between charging cycles.
If you’re really serious about battery power, you might add a second 12 volt deep cycle battery in a parallel circuit arrangement or two 6 volt deep cycle batteries in a series circuit. See the attached images.
Again, the difference is more “amp-hours” which means more success and less aggravation between charging cycles. If you’d like more information, pricing or would like us to do the work, give us a call.
