Charges battery to full, then trickle charges to maintain. My 2005 GTO sits for weeks without being used. I hooked it up and it told me my battery voltage was to low. My battery was junk and needed to be replaced. This will happen to you if you don't start it weekly and let it run for a while,or hook it up to a trickle charger. I installed a new battery and charger keeps it at full charge. This is a very nice product. I don't have to worry about using an extention cord.

I bought this to use as a battery tender for our boat which doesn't get enough use. I built a mount out of ABS pipe so I could mount it above the boat lift. It works very well, it charges even when the sun is hidden behind clouds and I have not had any dead battery probems since. Having a visible indicator that it is working is a nice feature. It is a good quality product that doesn't seem to be bothered by the weather.My only complaint is that they (the mfg) doesn't tell you which model to use for a given purpose. That would be helpful.

I bought this item to keep the battery on my car in shape. The car has sat since December and had a dead battery. The battery was fully charged in a day and I am very happy with how well it works. I would give it 5 stars but the cables are very short. I have a Mini Cooper with the battery in the trunk and the cable could not reach the front seat, if I had to connect in the engine bay I would be forced to buy the extension.
