Best one available

I'm not one to leave reviews. I've tried many knock-off brands. Battery Tender is the best there is. Worth the few extra dollars to own a high quality, consistently reliable, dependable, and expect it to last a lifetime, rather than just a couple of years.

Can't say much. Was Christmas gift, haven't used it yet. But, purchase was easy, fast delivery, packaged well.

Great battery maintainer

I have had this charger on my UTV the past week. It is outside and has been keeping the battery topped off even in sub zero temps. I have owned and used the same model for several years on my other equipment.
