hey steve, i got one this year and then bren bought tear em up one too for xmas, i like it, and talk to tear em up i dont think he likes it as much as i do but he likes it better than the antique he had. im pretty sure i got it at wal mart and its set up to charge any battery from a small lawnmower batttery to a car battery. what i like about it it shows you how much of a charge is in the battery when you start and shows as its charging what % it is at, although we have found out you sometimes have to unhook it and rehook it to get a change in the % of charging. it also wont overcharge and actually conditions the battery if you forget about it and does not fry it, somthing to do with de sulfinateing the battery?? i could be wrong on my terminology and ill get back to you with the model and name of it, but send tear em a pm and see what he thinks too. talk to you soon. gduck
