  1. BatteryMINDer® Model 1500 is amazing

    Posted by John T on 6th Jul 2017

    This little device is amazing. I hooked it up to a battery for our inboard boat that had not been charged in over 6 months. Though its voltage still was at 12.43 volts (I guess the battery was still in at least fair condition). In looking at the top of the plates (not a sealed battery) they appeared grayish. Within 10 days the plates started to look much darker. I will leave the BatteryMINDer on this battery as long as it is out of use and not in the boat.
    I plan on purchasing at least one additional unit. At this reasonable price it will certainly pay for itself many times!

  2. Works Like A Charm

    Posted by David Kendall on 20th Sep 2016

    Got it, used it, love it. If it continues to work as it does now for a long time, what's not to love?

  3. wonderful product

    Posted by Unknown on 30th Jun 2016

    We love the fact that they're easy to use and they're compact.

  4. This is my second one.

    Posted by Paul Gemme on 4th Nov 2015

    I had the same model previously and was quite satisfied with it but it stopped working after a year and a half. So I ordered another one (same model) and it works as well as the first. Hopefully it will last longer.

  5. modle 1500 charger/maintainer/desulfator

    Posted by Max on 19th Aug 2015

    This is the second of these I have bought. the first on I keep hooked up to my three boat batteries---works great! I took the first one I bought and hooked it up to my truck battery( before if I let it sit for one week It would be dead--after leaving the desulfator on the battery for 2 weeks it rejuvenated my battery---now it will start right up after sitting for 2 weeks or more . So I just bought a second one for my motorcycle and trike and car It is easy to hook up quick disconnects---I would highly recommend this product even to my grand mother! this product is well worth the price---and they have great customer support--if you have any problems on how to hook it up (it comes with instructions) but if you are like I am and need help call them and a technition will guide you through the complete installation This is a very good investment and it will maintain up to four 12 V DC batteries at the same time. You will not regret buying this product it will pay for it's self--and only costs you less than one penny a day in electricity. I'm A tried and true believer in this product.

  6. A cut Above the rest of the competition

    Posted by Bob Bagwell on 28th Jul 2015

    Doubles to triples the life of my batteries according to my FAA I A who also owns a Comanche.
    A great investment!
    My Comanche battery costs over $300 so my investment is more then paid for with many returns to come.

  7. excellent product

    Posted by Unknown on 17th Jul 2015

  10. Great Product

    Posted by Unknown on 21st Apr 2015
