How many hours to charge an automobile battery?

Asked by: ed
Firstly, this is designed to be a battery maintainer rather than a battery charger. While it will charge a dead battery, depending on the size of the battery and the depth of discharge it will take a very long time to charge using this 1.2A maintainer. Regarding how long this would depend on the size of the battery, the depth of discharge, age and condition of the battery as well as many other factors. A maintainer is designed to keep an already charged battery charged during storage.

120-Volt Battery Maintainer is rated 4.4 out of 5 by 77.

Charged car battery twice and power washer battery once. Left it plug for a month (no load), and it became broken. Took it apart to see what failed. The internal fuse was intact. Something else was broken. The PCB was poorly designed and manufactured, and I lost interest of repair.

Rated 5 out of 5 by from So far, So good Its a really, really slow charge but it does charge and maintain. I put it on my camper deep cycle after each trip and it takes a couple days to top off, but it does work and then it switches over to maintain mode.

Rated 5 out of 5 by from Cured my car! My Subaru ran out of battery 2 years ago, and since then it's up very often. I had the battery checked and it was fine. So I tried this equipment and charged the battery. It worked and the car is very well so far.
