After a number of years, usually about 4 to 5 years, the plates inside of
the car battery get eaten away from the acid, and the electrical activity.
The fix is to replace the battery.

Hello..

I hope this post is related to this group because I think this is
about electronic a little bit.

Hmm, my car battery is almost dead. But, when I jumpstart it, it
starts well and the battery is also okay for another 2-3 start after
running it a while. Then, the next morning the car battery is flat
out. So, is there any method for me to revive the dead battery?
Because I think it is not fully dead yet, if I throw it, it would not
be good to the environment.

Thanks.
