So far so good.

I've had the Black and Decker Battery Maintainer running for about a week now and I am, so far, very satisfied with the product. I use three other versions of maintainers, all of which work but are considerably more expensive, to maintain the batteries on my ATV's, motorcycle, boat and RV and so far this maintainer works as well as the others. It offers three connection modes, battery terminal clamps, cigarette lighter plug and hard wire directly to the terminals. I prefer to hard wire directly to the terminals and the quick connect plug makes it a lot easier to disconnect when I am ready to play and reconnect when I'm done. Just remember this is not a battery charger! It will keep a fully charged battery functional and up to capacity but will probably not recharge a low or dead battery.

Black & Decker Battery Maintainer

This is a very nice trickle charger. This is third one that I have purchased. I use them on my Wave Runners and Motorcycle to keep the battery in good shape. Before I had these trickle chargers I used to have to replace my Wave runner batteries every season but now they last several years. I would recommend this trickle charger to anyone that is tired of replacing batteries prematurely

Great product

There are battery maintainers that go for around $100 or more. So I was skeptical about this one only being $20, but gave it a shot anyway. First thing I notice is the plug accessories which are very cool. The device is simple to use and the most important thing is that it works. Hooked it up to my old jeep (battery was dead) it took about 2 weeks but charged the battery and keeps it charged. So I hooked one up to my boat battery and it was fully charged in 2 days. Will probably get a 3rd for my atv. These things are great and cheap.
