1. Do not remove the plastic covering the adhesive and then try to align the battery. Leave the plastic on and remove one at a time after the battery is aligned.
2. Use masking tape to hold the battery cells together while aligning, otherwise they flop around a lot.
3. Put your speakers next to the battery cells (before removing plastic on adhesive) to ensure you’re leaving enough room.
4. Make sure your battery connector is well aligned too.

Take a look at the trackpad replacement guide to get a sense of where the adhesive is:

I also forgot to flip the ZIF connector. Thankfully my trackpad worked after.
Make sure to flip the ZIF connector before putting the trackpad cable back, too.
