Is it possibly to charge a 12v 100ah sealed battery when it is only giving off 5.5v?

Question

I have a 12v 100ah sealed battery which was given to me. It is around 8 months old. I tested it and it was giving off 5.5v. I tried connecting it to a 35w solar panel (using a regulator) and taking regular readings. It was left for a week and there was still no change to the voltage in the battery.

I then tried connecting it to my car battery charger for a few hours (a 10amp charger) - still the battery will not increase its charge. Is there anything I can do to get it back up to 12v?

Answer 1

Probably not(short of rebuilding).Sounds like the cells are shorted.

Answer 2

THE CELL'S ARE GONE TO HEAVEN,  OR WENT TO SEE THE DEVIL..GO OUT AND GET ANOTHER ONE, AND GIVE THE OLD ONE A DECENT FUNREAL.

P.S ---DONT GORGET THE FLOWERS

Answer 3

Is it a wet or dry battery?  If you really like to inspect what is going on you have to open it carefully in a well ventilated place, use protecting gloves and glasses and no children around.You can look at the connections between the cells and see/test  if they are still functional. if not you can try to rewire the cells. Possibly some cells are dry(in case of wet cells) or are "dead" for both wet and dry cells. You also can inspect  which cells are working by disconnecting groups and test what the voltage and amperage is of these groups. Repairing the battery is not really an options when cells are dead,  it is a lot of work to get everything to replace the dead cells, thus not recommended.  The answers with the funeral/disposal options you already received are common sense.  Only if you like to  learn more about batteries then dig into the How stuff Works website and learn about batteries http://www.howstuffworks.com/battery.htm and start inspecting carefully the battery you have with in the back of your mind that at the end it still ends up as a disposal.
