    • Open the housing plate.

    • Be gentle with the wires still connected to the logic board so as not to ruin the cables.

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.

Good guide ! less than 20 minutes to change the battery, cleaning the interior included !!

Any thoughts? I replaced the battery and reapplied the thermal grease. iMac still won’t turn on.

Did you check voltage of the new battery? Should be 3.6v.

Otherwise it could be a logic board or PSU problem.
