STANLEYBM1S Fully Automatic 1 Amp 12V Battery Charger/Maintainer with Cable Clamps and O-Ring Terminals

I just use this little charger again today. Great trickle charger for and 12v battery

Works great. No issues. Saved my bike from the winter months.

This unit is very small. Not real bulky like a lot of other maintainers. It has a long cord on both ends. Has 3 different hook up choices. I use the permanent mount to the battery. I stick the quick disconnect out the front grill. This unit is automatic. When the battery drops in voltage the maintainer turns on, then when the battery charges up. The unit turns back off. No wasted electricity or overcharging of the battery to boil the acid out! Peace of mind knowing the battery is fully charged when the vehicle is parked for an extended period of time

Very compact.

I like that it has a long power cord and connecting end. 12ft which allows it to reach from the outlet me my garage to the car without using an extension cord. Wish it had a magnet on the back like the previous larger version I had so that it could stick somewhere.

Made it through the deep freeze and battery fired right up. Works great.

Bought for my tractor battery. Other chargers were having trouble charging this 10 year old battery but this little sucker worked. Got really hot for a couple days but battery finally charged and tractor started.

I used this charger to maintain my motorcycle and lawn mower batteries during the winter months. It is very easy to hook up, is almost too easy to use, and has kept my battery well maintained. I feel there is very little that can actually go wrong with this which is a good feeling to have especially when dealing with electricity and potential fire hazard. I have no hesitation recommending this for others and plan to purchase a second for myself.
