Battery problem, Kindle 7th PW. Is it normal it heats a bit on the back?

Hello, I usually have a cover on, so I didn't recognize it before. Is it normal it's a bit hot in the bottom part? Actually if I disassemble the kindle that area that is warm outside, is really hot inside. I'm having battery problems and I want to understand if it makes sense to replace it again, or there is another problem. In fact I've replace the battery already 2 months ago. The battery started to drain really fast, like after 6-8 hours of use. Then I would get a -22 battery error. So in July I replaced it, but the replacement battery was an "unused", according to the seller, second hand battery. After replacing it the error disappeared, but also this battery would last only a few days of light use. Now after 2 months I've got the same -22 battery error also with this battery.So at this point I don't know if it was a faulty battery, or there is another hardware problem.
it does get warm both with the original battery and the second hand replacement
This is what the second battery log says
