I have one, connected it to the battery in my motorcycle for a month, left it on the "de-sulfhation" mode for the entire time. I took it off the motorcycle battery and hooked it up to the TM battery in the boat (about 2-3 yrs old) on 2/15. I just happened to check the status of the battery in the motorcycle today after work with a DVM and it read 12.49. Did not have any charger on the bike's battery since 2/15. I did not check the volts with a DVM when I took the batteryminder off of the bike battery on 2/15. The instructions say to let the battery rest for 8 hrs before testing with a DVM so I can't say how much of a charge the bike's battery lost. Both batteries mentioned are at least 2, maybe 3 years old, and getting a bit weak imo. Will it work, don't really know. I plan on taking the boat out tomorrow, and just wonder if i will be able to tell any difference with it being on for only a short time (10 days). my guess is that the de-sulfhation process takes a good while, so 10 days is not anywhere near enough. The theory is good, but not all theories work in the real world imo. Did I waste my $$, maybe, but I could have postponed having to buy a battery for my bike and boat, and then again, maybe I didn't postpone anything. Time will tell. Being a smart charger is a good thing, as I have a battery tender brand smart charger that I normally use on the bike. I have read both sides of the arguement, keep a battery fully charged and it should last longer, vs allowing a battery to lose it charge slowly over time, and then charging once a month. I have followed/tried both methods, and the batteries usually last about the same amount of time. The reviews seemed positive anyway if that helps.
GO BIG ORANGE !
I meant to behave, but there were just way too many other options available at the time.
