Review: Excellent battery upkeep for cold weather lesser driven vehicles. - This battery charger/maintainer works excellently with almost no effort to recharge a weak battery or maintain a battery in cars that aren't driven regularly. This is especially important in colder weather as the charge can drop enough to be unable to start the vehicle. This almost happened to my 2011 BMW 535i Xdrive 95Ah battery after not moving it for 2 weeks mid winter. I got several low charge warnings but thought they would go away once I drove a bit, but trips were far and few between. The charger power cord is hard wired, and the output leads have a fast clip connector at the far end to plug in either the alligator clip ends or 1/4" eyelets for a more permanent connection to make frequent charging easier. Both the power cord and the output leads are 6' long for a total of 12' plus another 18 inches for either the alligator clip or eyelet connectors, so there's plenty of length to position the charger where you want. The clips are spark free and have polarity protection so you don't have to worry about those when making your connection. Plugging the device in starts it in standard vehicle battery mode. Other modes include motorcycle for smaller vehicles, AGM for those batteries, and a reconditioning mode to restore full capacity to batteries that have lost some charge capability. From almost dead, it took about 28 hours to go through all 7 phases of charge. Patience is the way to go here, don't check often, especially if you have to open a door or hood to do so. I found it best to leave it under the hood with it slightly ajar and check every 4 hours or so. Resist the urge to unplug it because you think it's not progressing. It is. Even in cold weather it will get your battery back in great condition with little more than the press of one button. Highly recommended.
Review: Valuable emergency car tool - This charger is awesome. One of our cars (a hybrid) went completely dead from lack of use for several weeks in the very cold winter we're having this year. Tried a bunch of times but couldn't jump start it. A friend recommended this product to me to trickle charge the battery. The product is easy to use, the instructions are pretty clear. It did the trick. Took about 18 hours but the completely dead battery was fully charged and the car was completely operational the next day. Real life saver because if you can't jump your car, towing and repair shop bills are next. I love it. And the alligator clamps were set apart with enough reach to get to the two hybrid terminals that weren't as close together as they would be on an actual battery. I also appreciated that the wire from the clamps to the box was long enough for me to rest the charger on my garage floor instead of on top of something under the hood for such a long period. I highly recommend.

### ⭐⭐⭐⭐⭐ Very good charger and maintainer.
*by A***O on January 25, 2026*

I have two of these chargers. One that I have been using for 4 years and the other for 1 year. They work great and are in almost constant use for keeping a tractor, a mower and a motorcycle charged and the batteries maintained. They are not cheap but I believe that they are worth the price given how well they work, how long they last, and how they extend battery life.
