"I am using an original 87w magsafe"
This machine requires 96W charger; accepts 140W too.

hi again, now I have 96W charger but same problem..

Is the battery recognized at least?
Any history available?

Be sure the flex cable makes good contacts; check the terminal from battery side too.

The computer did not turn on, with a new battery it did turn on but the message "the battery is not charging" came out one day it stayed on and went down to 5% now it turns on the apple comes out and halfway through the progress bar it turns off.

I'm going to check the connections as it says

I check all connections and change with other battery

Save data and do DFU restore.
Reinstall the original macOS which came with this machine.

I have tried several cables, including new ones, and I can't finish the process.

I am going to try to charge the battery again and repeat the process with a battery with at least 50% charge

Try flashing U4770.
Don't forget to make a backup first.
