Review title: 12V Battery Charger
Product review: The Battery Tender Jr looks like a quality "smart" charger that should solve our auto battery issues. We leave our truck idle for months while we're off sailing and we always returned to a dead battery. I started disconnecting the battery, which worked, but required resetting all the presets and sound settings on our audio system each time. This seems to be an inexpensive solution to the problem and probably much better for battery health and longevity.
