We are not allowed to use screwdrivers to pry open stuff. Unfortunately, that is exactly what we did in step 6 of Dissasembling the back up battery

Don't you need to replace the thermal paste?

Yes you do in the areas circled in orange. I'd also recommend changing the paste under the heatsink itself as that will probably be dried up.

I love my very first Mac ever, it is still working. After a couple of time living with its amnesia (forgot time and what else…) I’ve decided to replace the battery. Thanks for this helpful article. It made it easy to me to replace the battery.
