My original battery wasn't holding the charge anymore
The repair was easy and simple. No trouble at all.
Always get the batteries from a reliable source, such as your company.
This is an aftermarket replacement battery, NOT an Apple OEM part.

Replacement battery failure. Expanded into the track pad also.
The last aftermarket battery not so good of quality - not from iFixit. It expanded into the track pad. I also discovered that one of the motherboard power connection pins was bent so that two pins were connected into one of the 9 pin fema . . .
My battery wasn't holding a charge for more than just a few minutes even when fully charged. It had to be on the charger to work.
Repair went great, I would HIGHLY SUGGEST you buy the correct tools upfront... It will save you time and trying to find the right screwdriver was hard. Ended up spending $ . . .
