    Customer Product Reviews

    Rated 4.7 out of 5★ by 58reviewers.
    Rated 5 out of 5 Dual Charge Capability and Mulitple Attachments For the price this unit delivers. Both in 6 volts and 12 volts. It comes with multiple battery attachments which most of the other units out there do not. I used the permanent attachment on my garaged vehicle which rarely sees the road, and then I have the other two attachments remaining which I can use to 'spot' charge my other vehicle/lawn mower/generator batteries to keep them topped up and in their prime. I purchased this B&D Battery Maintainer due to a dead battery found on my garaged vehicle from less than 2 years new!!! The result of not much vehicle road use and a slow discharge brought the battery down so low it could not recover. Now I can spot charge it and keep it in prime condition and avoid another $120 plus battery purchase. I also have the advantage of using it with the other supplied attachments on my lawn mower, portable generator and other vehicles batteries. A great value. 09/05/2013
    Rated 5 out of 5★ by 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. 07/29/2013
    Rated 4 out of 5★ by charge and defect light are very dim; hard to see Other than the indicator lights being very dim the unit is excellent. 1.5amp trickle charge is great to maintain car, bike, boat and yard equipment batteries. The three different charge connectors give you options of ways to charge each item. 10/22/2013
    Rated 5 out of 5★ by Great product at a great price! Easy to install, works great, and cheap price! It doesn't get any better than that. 04/27/2013
    Rated 5 out of 5★ by 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. 06/07/2014
