    Customer review by Grandma

    I only drive my car a few times a month and then only a few miles so the battery tends to get low. I purchased this to top off the charge periodically instead of having to replace the battery every 9 months to a year. It was easy to hook up with the mini clamps which are familiar to me. I purchased a heavy duty extension cord because I wasn't sure the cord that is attached would be long enough, but the cord is longer than I expected and I didn't need the extension cord after all. The car was cranking pretty hard so the charge must have been pretty low as it took two days to fully charge. That was several weeks ago, and it has been starting fine ever since. The indicator lights are a godsend for non-mechanical people like me, red for not fully charged and green when done. It also has an indicator if the clamps are hooked up wrong. Idiot proof. I am thoroughly pleased with this purchase.

    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

    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.

    I like the indicator lights. Used for a lawn tractor that must have a minor current bleed. This keeps it charged.
