Winter is in full swing - especially if you're in the Midwest or Northeast United States! Hopefully you've prepped your RV for storage, or in the process of doing so. Once spring season comes and the polar vortex cold front is gone, your trailer will still be in tip top shape for camping. One of the most important steps for winter storage is to keep your batteries in good shape and ensure that they survive the winter! 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?
Keeping 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 you hundreds of dollars so instead of saving it and using it on the next adventure, you have to get a new battery instead.



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?
Torklift has designed a high-quality locking aluminum solar battery box called the PowerArmor Solar. It features a lockable slide top that can easily be accessed no matter the mounting location. This dual battery box comes in a bright tread diamond plate design featuring a black high impact powder-coated frame for durability. The box bolts directly to RV, trailer tongue, boat, camper bumper, etc. The PowerArmor Solar also has an access port that allows electrical wires to pass through the side wall of the box to easily connect to your electrical circuit system and keep them safe. So, not only will it help keep your batteries safe from overcharging or undercharging, but also safe from the cold front that's quickly coming in.

How does the PowerArmor Solar keep my batteries charged?
The 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.
