Galaxy tab 3 8.0 won't charge and turn on

[Dan4o]

Hi, my Galaxy tab stop charging and won't start.
I open it and disconnect and reconnect the battery but the problem still exist.

Also I try hold power button (30 and 60sec) , power + volume up, power + volume up + home

Again with no effect.
So Is there any other way to fix it ?

P.S. when I disconnect the battery I charged it with charger connect directly to red and black (+ and -) cable to 4.2 V. So the battery is charged.

I connected it in tablet and the voltage is 4.18 ,when press power button voltage drop a little to 4.16 but again won't start .

Welcome to the forums. The device itself is roughly 7 years old. It's possible that this is more than a battery issue. The storage chip may have been corrupted. If that happened there might be no way to turn it on.

Is there chance to turn it on If I change the battery with a new one ?

Hi, welcome to AC!
Getting a new battery you can try but dont forget that those sitting on the shelf going have battery degradation even purchased as new .
