120-Volt Battery Maintainer is rated 4.3 out of 5 by 102.
Rated 5 out of 5 by from Worked well for battery topoff Extreme cold has hit the St. Louis area and my four year old car battery was feeling weak. I got this maintainer for $20 at Home Depot and hooked it up to my car as was going to be out of town for three weeks. It is a nice unit. Only thing I would say is that you should put this on a timer so that it can reset every day. Otherwise it will only charge the battery one time. For example have it turn off for an hour and then restart again. Good cheap unit. Probably won’t last as long as the really nice ones but for my intermittent uses it will work just fine.

Charged car battery twice and power washer battery once. Left it plug for a month (no load), and it became broken. Took it apart to see what failed. The internal fuse was intact. Something else was broken. The PCB was poorly designed and manufactured, and I lost interest of repair.

The Black and Decker 120-Volt Battery Maintainer offers several ways to connect to the battery(s) and the necessary hardware for each type of connection is included. I'm using the unit to maintain the charge on my diesel truck's two large batteries and it seems to work fine.

So far the car has started each time we have used it, normally has to be jumped after setting for several weeks. Wished i had done this a long time ago. Very nice that it plugs into the cigarette lighter.

I hoped that at this price, it would not be very smart, but it needs to check the polarity of the connection. I had to jump start the car, run it for a while, then put on this charger. After that, it worked OK.
