Review on Genuine Subaru J601SFJ000 Battery Warmer by Stephen Olson

This battery warmer is a true lifesaver for cold weather camping trips! Using this automotive product our team found that it kept our battery warm and functioning even in sub-zero temperatures. We were able to enjoy comfortable heat and electricity while OTHERS struggled with dead batteries. The installation was straightforward, and it fits perfectly on our RV battery .The only downside is that it only works when the engine is off. Overall, a great investment for anyone who wants to ensure a hassle-free winter RV experience..
