Review on ⚡️ STANLEY BM1S 1 Amp 12V Battery Charger/Maintainer with Cable Clamps, O-Ring Terminals - Fully Automatic by Brandon Gaines

I ordered two of these first. When they arrived one absolutely didn't work from the start and I sent it back for a refund. The other seemed fine. I hooked it up to a deep cycle battery for a few months and was fortunate enough to order it for another battery. Luckily it was on standby because my existing one just died for no apparent reason. So I canceled my current order. Unfortunately I'm outside the return window for another. I would definitely avoid this product. The battery should last for years. This one has a bounce rate of 67%.
