Is There A Way To Keep RV House Batteries Warm During Winter Storage?
Published 11/04/2025
Question:
Can I use the 80-watt Zerostart heater with my RV house batteries during winter storage?
asked by: Tim
Expert Reply:
You can absolutely do that, Tim. The 80-Watt # ZE87FR works great for Group 24–27 batteries that most RVs use (some even use group 31, which this heater fits as well). Just wrap it around each battery and plug into shore power or a timer so it cycles a few hours at a time when temps below freezing. Keeping those cores warm will help the converter maintain charge more efficiently.
Are your batteries flooded or AGM? That can affect how long you leave it plugged in. This will not be good for Lithium, so make sure you don't have that type!
