Battery MINDer BM1500 is Excellent
Pros: I'm delighted with my new Battery MINDer BM1500 Charger/ Desulfator. I charged and conditioned a 2-year old AGM Scorpion Battery I purchased from, and then charged and conditioned a 10-year old AGM YUASA Battery. This is one smart charger! So very glad you carried this product.
Cons: None
Other Thoughts: To further protect my new BM1500 I purchased a 3-outlet surge protector for its use in one of the main outlets in my garage.

Pros: I have used the BM1500 for the last few months on two Xantrex battery packs (a 600HD and a 400X) that had been underperforming. In tests prior to using the BM1500, both maxed out at about 80 watts of available power. Repeated tests using the BM1500 on both units have increase capacity to a minimum of 150 watts. The newest unit is about seven years old, so I was not expecting a miracle. Tests are ongoing as I write this, but my opinion thus far is that the BM1500 is worth the price.
Cons: Progress is much slower than I had anticipated; but it is progress none the less. Patience is the name of the game. I have also learned a lot about sealed lead-acid batteries in the process. Existing technology is not of the caliber that I had originally expected.

It fixed my battery
Pros: Works as advertised Simple to use Fixed my relatively new but quite dead AGM battery in 2 days
Cons: None
Other Thoughts: I bought a Scorpion sYT12CL AGM battery from Battery Stuff a year and a half ago. Over the winter, I had it on a 12V charger from NAPA. At the beginning of this season, the battery was dead! I called up Battery Stuff. They recommended the BM1500 thinking my battery was sulfated. I had the old battery on the BM1500 for 2-3 days, and it was as new. Really. I left it off the charger for 1 week...Started up a new first time. The BM1500 has spared me the cost and hassle of fitting a new battery. I definitely recommend this product for battery maintenance.

Battery MINDer
Pros: I have the original "black" model, without temp. compensation. I have also use "other" brand chargers/maintainers that are so-so, but the Battery MINDer is simply amazing. If I did not own one and use it, I would have never believed it. I've SEEN the the sulfite at the edges of a translucent, wet-cell, lead-acid motorcycle battery vanish over time. I ended up getting 8 years out of this OEM battery. Most recent cure was for a very dead 12V AGM battery on another m/c. Found it totally dead, due to a 6/12V switch in the wrong position (other brand charger). Battery MINDer would not charge it, until I forced a charge, with a jumper/booster. Then the Battery MINDer was ok to charge it. To my amazement, after 1 week, the m/c STARTED. I had written this one off, but saw this one come back to life.
Cons: Are there any?
Other Thoughts: Amazing

Battery Minder works great
Pros: Charges the tractor battery, desulfinates (removes sulfate from battery plates), I don't have to continually check to make sure I am not over-charging, keeps battery charged and prolongs the life of my expensive tractor battery.
Cons: I really can't think of any offhand.
Other Thoughts: BatteryStuff website is loaded with good information about maintaining batteries and they don't try to sell you things you don't need. My items shipped very fast and were cheaper than buying them at the local tire store.

Battery Minder
Pros: I've used Battery Tenders for a while. I even added desulfators in parallel. Then I discovered Battery Minder with built-in desulfators. The Battery Tenders are great for interim usage, but the Minders are much easier with less hassle for long-term storage. Now, if I can only get rid of a few modified [with quick-disconnect] desulfators...
Cons: The Battery Minders are more expensive than Battery Tenders, even with the added deslufators. Plus, I'll never know if they work until a battery fails, which could be years.
Other Thoughts: The optimist thinks that the jar is half-full; the pessimist thinks that the jar is half-empty. The realist thinks that the jar is just too damn big for the job.

Battery Saver
Pros: Charges and saves the battery at the same time. I don't know of any other product that desulfinates the battery.
Cons: None
Other Thoughts: I have replace my motorcycle batteries every year prior to owning one of these. I am now on my 4th year with one of them and it is still starting the bike easily.

Battery minder
Pros: I've used battery minders for 20 years used them on tractors motorcycle and cars that are stored for years. They will not boil a battery dry have one tractor battery 15 years old still going. Best charger for the money because they keep battery desulfated and charged.
Cons: No cons
