3ds battery bug

[Mikalello]

Hello!
My 3ds, for some reason, when it is at a battery percentage between 50/60%, has strange bugs: It shows the red light flashing and the 3ds turns off, but if I close the 3ds before shutdown it comes back to having the classic blue light, but after a few seconds the red light starts flashing again.
The strange thing is that when I turn the 3ds back on it shows me the battery is charged at 50/60%.
I tried to change the battery but nothing happens

If you have cfw, installed you can use either Battery Mark v2 or 3DSident to see the correct percentage the battery is at. The official one is misleading and vague.
So you've changed the battery with a new one and the same thing happened? The red light appears when it its at 3/2 lines? Have you tried charging the new battery completely?

Does the battery look swollen or anything like that?

no because one screw is damaged and cannot be removed

I had an issue on a new 3ds xl where the battery level would report when the battery was connected, but wouldn't change until disconnected and reseated. The fix was to replace the battery daughter board.

I believe I had accidentally put the battery on backwards when I had the thing disassembled.

How so, when it can be placed only one way?

When disassembled, nothing prevents you from connecting it the wrong way.
