What customers say about "Key Specs"
BatteryMINDer 12117 Charger/Maintainer/Desulfator
  • This charger has saved me hundreds of dollars by reconditioning marginal batteries. Many times when a battery is accidentally drained, it becomes internally contaminated with deposits that can make the battery look dead.
  • These are great and will keep your batteries maintained and operational for much longer than using a regular battery charger.
  • This charger actually does what it says. I know that sulfation supposedly cannot be removed. One of these batteries, a Marine deep cycle, I equalized to 16 volts and it still rested 12.4 V.
  • I love BatterMINDer products and have several. This is relatively inexpensive and easy to use. It comes with two battery connectors - alligator clips and round lugs.
  • My one issue is it having a close circuit to the battery connectors when the charger is not connected to the wall.
BatteryMINDer 1500 Battery Charger/Maintainer/Desulfator
  • This unit has a timer-controlled multistage algorithm including: Battery Check, Constant Current Charge, Conditioning Charge, Desulfation Check, and long-term Constant Voltage Float Charge.
  • It works flawlessly for both Automative Starter Batteries and Sealed AGM batteries. I can leave the charger attached for months without fear of 'cooking' the battery.
  • This is will charge a battery fully, but for a car battery expect it to take days especially if completely dead.
  • Overall a great item to keep your batteries in shape for non used equipment. It works well on both AGM and older Lead Acid batteries as well.
  • I don't think it works, I try it couple of different batteries. I don't see really any improvement to internal resistance values. I do a battery tester that give me storage capacity and internal battery resistance.
  • Twice now this unit has discharged a marine battery down to 9 volts over a 3 day period. The battery started off at 12 volts. Apparently this unit is faulty. don't know if I can return.

  • Small and handy, comes with gator clips and bolt on terminals for easy hook up to your vehicle battery.
  • Good product, easy to use, small in size and I bought it on the commendation of the RV sights that i visit.
BatteryMINDer 1500 Battery Charger/Maintainer/Desulfator
  • It is small and compact and plugs directly into the floor outlet.
  • Very compact and seems to work well. I've used this charger to keep my ATV, jet skis, and motorcycle batteries charged up.

What customers say about "Features"
BatteryMINDer 12117 Charger/Maintainer/Desulfator
  • I think the best feature of it is the desulphation function. Maybe it is luck, but two of our car batteries are over 9 years old and still running strong.
  • As another nice feature it includes various methods of connecting the Batteryminder.
  • The fixed mount and alligator clips with the quick disconnect plug is a nice feature. I keep the fixed mount on my backup sump pump and the clips I use for the vehicles.
  • The indicator light is a nice feature to let you know the state of charge.
  • I think this is a better product because of the Desulfator feature.
BatteryMINDer 1500 Battery Charger/Maintainer/Desulfator
  • Does produce a 'DeSulfation' Pulse which may be effective in reviving and/or preventing mild Sulfation.
  • The biggest benefit/feature of this charger is to inexpensively desulfate and maintain your batteries.
  • Another great product by Battery MINDer. The desulfation feature is what sets this companies chargers apart. If you have a tired old battery, try desulfation.
  • I don't like it. At least with my marine deep-cycle battery. the green light always blinks and never goes solid, the blue light flickers - sometimes at a random frequency.
  • I bought this item a few months ago, at first it worked great I gave it 5 stars, but now after only using it 3 moths it just stopped working, I don't know if I got a defect or it's just not a good item, so I'd beware before I buy another one
