Problem with battery in HP Pavilion dv6500

[Kapejog]

I have a strange problem with the battery in the HP Pavilion dv6500 laptop. Some days ago I got dv6700 with a damaged BGA so that I could descrew for fun. I noticed that there is a battery in it. So I put it into my DV6500. And here the problems began. Under linux, I normally charged it to around 70%. The next day, when I turned on the laptop, I had only 12%, where after a while there was an alert about low battery status. Now, when I started to test the battery under Windows, it loads very long and very strange. The program for monitoring the battery status says that the battery "disconnects" from charging every minute and starts charging again. Currently, about 7% charged for an hour and I do not know what may be the reason for such a slow charging. In addition, the same program claims that the battery has not been charged (battery cycle). I am adding 2 information screens, maybe it will give something.
(battery is original)

Make a diagnostic tool with this. Reboot and spam F2 on POST, then there will be a battery test somewhere in the tool.
