Asus al31-1005 battery pack disassembly

It was not doing good after several years, and I've ordered replacement battery pack which will support my 1005HA for 5-8 hours.  Today, I took the plunge to disassemble it to get the 18650 inside for other purpose.

At the very beginning, I actually wanted to do it cleanly, for example, to even replace the 18650 with some new batteries but then the case was too thin and fragile.  Only three cells were inside.


They were from LG with 2200mmAh... not bad. Below is the circuit board for charging, etc.


I found a device which I suspected it to be a temperature sensor, to avoid overheating.


Most of the battery pack was indeed empty space.
