As iFixit has mentioned above, you’re running a risk using a heat gun near lithium batteries. If you’re going to go this route it’s essential that you fully drain your battery first.
3) Use the supplied plastic cards as ramps to direct adhesive remover towards the edges of the cells. This helps to block the adhesive remover liquid from splashing or running over towards the speakers. By doing this in combination with using the paper towel barriers I didn’t have any issues with adhesive remover getting on my speakers.
4) Cover the logic board, speakers, and fans with a few layers of paper towel or some other covering (just not anything metal) before you begin working on the battery cells. This helps prevent any drips/splashes of adhesive remover from getting on critical components. It also helps to keep them protected from other types of damage, such as the plastic shard that went flying when I broke a plastic card prying out one of the battery cells :)
Good luck with your repair!
As others have mentioned, I did this repair without removing the logic board, fans, and speakers. Keep in mind that iFixit isn’t condoning this and if you damage some part of your MacBook by going this route it’s because you took a shortcut. That said, I decided the risk of damaging the connectors or other fragile components involved in the full disassembly described above was higher than the risk of damaging my speakers with the adhesive remover. Here are some things I did to (successfully) minimize the chance of destroying the speakers:
1) Fold small pieces of paper towel and jam them into the spaces between the battery cells and the speakers. This created a barrier in case some of the adhesive remover got near the speakers.
2) Use a hairdryer/heat gun to loosen the adhesive on the two outermost cells (the two smallest cells). Be VERY careful doing this. You want to use a relatively low temp if you’re using a heat gun and don’t stick the gun too close.
Jeff, thanks for the response and the info. That’s an interesting article. I agree it’s definitely possible they’re still doing this. I’m down to about 71% capacity, so yes, definitely time to swap. A little frustrating since I only have 668 cycles on the current battery. I thought they were suppose to be rated for about 1,000 before dropping to about 80% capacity. Anyway, thanks again. I’ll be ordering a battery replacement kit from you guys soon.
Does anyone know if replacing the battery improves the MacBook’s performance? I don’t mean battery performance. I’m curious if there’s any noticeable difference in the MacBook handling computational/graphically intensive tasks like video editing, rendering, gaming, etc. As I’m sure we’re all aware from the recent publicity in the news, iOS throttles power usage and reduces speed on system wide functions as a device’s battery ages. I’m thinking macOS may do something similar? Has anyone done a performance test before and after replacing a battery in a MacBook? Short of that, does anyone have any anecdotal evidence of their machine performing better after replacing the battery? Again, I’m interested in processing performance, not battery performance.
