Should I leave my RV battery plugged in all winter?

RV Battery Blog 1Winter is near and hopefully you’re prepping your RV so once spring season comes, your trailer still in tip top shape for camping. Have you completed everything on your checklist? Don’t forget that one of the most important steps for winter storage is to keep your batteries in good shape! A common mistake that RV owners make is leaving their battery plugged into the RV converter to maintain its charge while in storage.


Why shouldn’t I keep my batteries plugged in all winter?

RV Battery Blog 2Keeping your batteries plugged in all winter long results in overcharging the battery. RV battery converters charge at a constant voltage that is too high for the battery over such a long period of time. Overcharging results in a fried battery that will no longer function to its full potential. The constant high voltage causes the electrolytes necessary for battery function to boil out, leaving the battery permanently damaged. Battery replacement can cost hundreds of dollars.


Should I leave it unplugged all winter?

That’s also not recommended. If your battery is left sitting and discharges to low enough levels for a long period of time, it will no longer be able to perform or charge up to its full potential. The battery charge capacity is also effected and won’t hold charges for as long as it had originally. Many think a quick fix is just to simply add water and recharge. This unfortunately doesn’t help the battery regain its charging ability. You’re still stuck with a battery that isn’t operating to its full potential.


What can I do to AVOID either overcharging or undercharging my RV batteries?

How does the PowerArmor Solar keep my batteries charged?

RV Battery Blog 4The PowerArmor Solar locking battery box features a Zamp 10-watt solar panel that extends battery life up to 400% and prevents premature battery replacement. This means that you can keep your battery plugged into the PowerArmor Solar all winter and it will trickle charge your battery – ensuring that it maintains its existing condition all winter. The slow trickle charge reduces the chances of both over and undercharging with exposure to sunlight.


But what if I have more than one battery?

The PowerArmor and PowerArmor Solar are offered in multiple different sizes for all your RVing and boat battery needs. Including the PowerArmor MAX that holds up to five batteries.

Being in an environment in which I can problem solve is where I flourish. Every answer to a problem leads me to a new concept to understand or a lesson to learn. When I'm not solving problems I enjoy camping and going to festivals with my family - from the local city center festivals to the mountains of Wenatchee at the Winter Grass, blue grass music festival. Experiencing culture is where my heart is content.
