Why do my RV batteries drain so fast?

Why might your RV battery be draining too fast? You may have more power draw on the batteries than you think you do. Dome lights and headlights left on are two common culprits. Furthermore, you should disconnect the ground wire while it is in storage to prevent that from draining the battery when it isn't in use.

What would drain the battery on an RV?

Camper batteries can die for many reasons, these being age, overcharging, undercharging, too much device draw, parasitic loads, or not enough amp hours. Taking care of your batteries is the first step to prevent them from dying. The number one takeaway is to never let a Lead Acid battery drop below 50% state of charge.

Why won't my RV batteries hold a charge?

If your camper trailer battery is not charging, the way to troubleshoot is to check for corrosion, battery charge health, and converter issues. Your circuit board may have blown fuses, diodes, and resistors, or the shore power may be at fault. Proper maintenance is the key to battery health.

How long should an RV battery hold a charge?

"Under normal use conditions- lights, propane refrigerator, charging phones etc and water pump, a 12v battery will last 2-3 days. This time can be extended by conserving electricity- conserving water (not running the pump), shutting off lights as much as possible- or simply by upgrading or adding extra batteries."

How can I make my RV batteries last longer?

Hot temperatures and overcharging will kill batteries. When it's hot outside and during periods of high battery usage check the water levels in battery cells more frequently. Checking the electrolyte levels and adding distilled water as required can save your lead acid batteries.

Parasitic loads like gas detectors, clocks, and other small electrical devices drain power when your RV isn't in use. If the power gets too low, it can hurt battery life. Your RV should be equipped with battery disconnect switches to prevent this, so don't forget to engage them when the RV is off or in storage.

How often do you need to add water to RV battery?

I recommend checking the water level monthly and after each RV trip. If you leave the RV plugged in, constantly charging the battery, you should check the water levels bi-monthly. Next it's important to know you only add water to a fully charged battery, unless the water level is already below the plates in the cell.

How do I keep my RV battery charged?

Lower temperature slows the discharge process down, and higher temperature quickens it up. Keeping an RV's battery charged while in storage is one way of prolonging the battery life. One practical way to keep it powered up is by using solar panels. Solar panels automatically charge any connected utility.

Is it OK to run RV refrigerator while driving?

RV refrigerators work best when using propane but 3 way refrigerators can be run on 12volt Dc while driving.
