RV Battery Selection Guidelines and Info

Batteries are one of the most important components onboard your RV and are the heart of most electrical systems.  A basic understanding of how batteries interact with electronic equipment can help you avoid being stranded when it counts the most.  RV batteries perform two important tasks on your vehicle, cranking engines and powering electronics.  In today’s RV’s, the standard DC requirements are at an all-time high and are used to power significant loads such as multiple TV’s, high powered acoustic systems, residential refrigerators, large cabin slides and sizable heater fans just to name a few.  As you weigh the importance and power consumption requirements of these and other DC powered components, you should be sure to build a battery bank capable of carrying the loads.

Three Main Considerations for Sizing a Battery Bank

A full assessment should be done to calculate the power demands of the DC powered electronics you will use onboard your RV.  It is wise to build a battery bank to be roughly twice the capacity that you require so you are able to optimize your number of battery life-cycles.  There are many online websites that provide DC amp consumption by appliance or refer to the panel on the actual appliance and/ or owners-manual.  Next you will have to measure the space available for batteries.  Sometimes you can gain reserve capacity by using six volt batteries, but other times it is more efficient to use twelve volt batteries.  Finally, you will need to select a charger that can satisfy your particular size battery bank most effectively.  If you will be using solar panels to recharge your battery bank you will need to size them properly and use a controller to regulate voltage for the best results.  If you are going to rely heavily on your alternator, you will need to insure the voltage is also regulated.  Once you have selected a battery charger you will need to know the basics of how to best manipulate the device to suit your batteries.

Caring for and Storage of Your Batteries

You should first determine the accurate ‘open circuit’ voltage of the battery bank.  This can be done by removing one of the main leads to the RV bank and making sure there are no additional hot wire taps that may have a load on the batteries.  If the batteries are fresh off a charge, they will need to sit for at least an hour to let surface voltages dissipate.  A fully charged healthy young Lifeline battery will show a voltage of 12.85 or higher.

Once you have determined your batteries are fully charged and that they will not be needed to perform any emergency tasks (carbon monoxide sensors), they can be left disconnected to insure they won’t be drawn down.  You can also maintain your battery bank by keeping a float charge going to the batteries.  If you don’t choose to keep the batteries connected we recommend an occasional boost charge about every 6 to 8 weeks to keep the batteries at a full charge.  Colder temperatures will reduce the need to boost charge, but occasional cycling of your batteries can promote a longer service life.

The definitive way to determine the health of your batteries at the beginning or end of the RV season is to perform a ‘true’ capacity test.  Once batteries have been completely charged, you should apply a 25amp load and monitor how many minutes your batteries run until the voltage reaches 10.5v (for 12v system).  By comparing this number to our published ratings, you will know the remaining capacity of your battery bank.
