I was having problems with the 12 volt battery in my new hybrid automobile due to having drained it too much trying to learn all of the apps on the dashboard while the engine was turned off. Rather than buy a new battery, I have used this device to recharge and refurbish the battery. - Over the past three weeks I have not had any problems. - The first time I connected the charger it took at

Typical of my Ford diesel pickup, after 4 years the lead acid batteries were shot. I bought this charger to help get me by until I could purchase new batteries and also to test the myth of desulphating. Boy was I wrong! The myth is true. 2 years later I'm still running those old batteries (now 6 years old) and they work fine. I couldn't be happier.

I start charging them in late winter one at a time in my garage after storing them for the winter and leave each one on for at least a few days or until they hold 100% charge (12.9-13.1 volts) after 24 hours. I purchased th

I found this to be a great charger, I call and asked how many batterys could be in line? At battery minder they said 5. Also I asked if you could but small atv batterys inline with the large rv batterys? Batteryminder said, Yes but make sure all the batterys are charged up to start with. So I took and built a jumper cable that plugs into rv 12v plug over to the battery of the atv's in the Toy
