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.

If it is 5 years or older, replace it. Plate sulfation and high-resistance
internal connections are common after 5 years or so.

Other problems to be investigated: slipping belts and a defective
alternator.

Car batteries should be recycled. Please be kind to our planet since we are
sort of stuck here for the moment.
