RV Batteries, Getting The Most Power Storage
Most RVs have an electrical system that simply plugs into a power source. When you’re at a more primitive site that has no power or water, your RV’s deep-cycle batteries had better be in top shape to power everything from your fridge, lights, stove and more. Many RV owners don’t always think about their batteries until they stop working, so it’s always important to make sure you have enough energy storage to power all your RV’s accessories.
The way to ensure your RV has plenty of standby power is to ensure the batteries have enough capacity to handle the power load of all of your RV’s accessories. First, It’s important to know that RVs require a deep-cycle battery for this purpose. These batteries provide longer lasting power compared to regular car starter batteries that are designed to provide maximum power for short periods (to start the engine). Each deep-cycle battery is rated in amp-hours (AH), a measurement of the battery’s capacity. Most are indicated in the amount of current in amps that the battery can provide for 20-hours.
For example, a deep-cycle battery with a 100 AH rating can deliver 5 amps for 20 hours, or 20 amps for 5 hours, before being discharged. Discharging deep-cycle batteries more than 50-percent will dramatically shorten their life. This is one reason why many experienced RV owners use batteries with the most AH rating they can get. When comparing batteries, make sure you compare them by the same 20-hour standard.
RV owners also switch to using multiple batteries to provide extra capacity. In many instances, this is done by using two smaller 12-volt deep-cycle batteries wired in parallel that will increase the AH capacity rating and leave the voltage at 12-volts. If you really want to dramatically increase your power storage, you can also switch to using two 6-volt batteries that need to be wired in series to produce 12-volts. This can more than double your AH capacity if you have the battery storage space to do so.
Keeping your batteries from being discharged below 50-percent is key to making them last longer, as can checking the water levels in the batteries. In some RVs, it’s difficult to access the batteries for monthly maintenance so some RV owners also install a single-point watering system that makes it easy to add water to each battery from one access point.
