You’ll learn how to open the MacBook, disconnect the battery, remove the glued-in battery cells using 90%+ isopropyl alcohol, and avoid damaging the trackpad/logic board while lifting stubborn center cells. After removal, we clean leftover adhesive so the new battery bonds properly, install the replacement pack (pre-applied adhesive or double-sided tape), then reassemble and reconnect everything for first boot. We also cover new battery calibration to improve percentage accuracy and how to reset the SMC if you notice unusual power or charging behavior after the replacement. Tools used: Torx T5, Pentalobe 1.2mm, spudgers/spatulas, tweezers, 90%+ IPA, anti-static brush. 🎬 Timecodes (chapters) 0:00 Symptoms: not charging, poor health, swollen cells 0:19 Tools & materials (T5, Pentalobe, IPA 90%+) 0:42 Remove bottom cover screws 1:00 Disconnect battery connector (safety step) 1:14 Trackpad cable cover + locking tab 1:59 Remove battery board screws 2:06 Peeling off the battery 2:18 Blunt needle warning 2:27 Lift outer cells (slow pry, re-apply IPA) 4:42 Center cells: strongest adhesive + trackpad caution 6:17 Remove battery + clean adhesive thoroughly 7:31 Install new battery (adhesive/tape placement) 7:59 Reconnect battery + reassemble bottom cover 9:54 First boot + plug in charger if needed 10:05 Battery calibration steps (100% → drain → recharge) 10:22 Reset SMC (charging/power issues after repair) 10:51 Wrap-up + SSD upgrade mention 🌟FAQ ❓Question: What model is this battery replacement for? ✔️Answer: The MacBook Pro 15-inch (2015), commonly referenced as A1398. ❓Question: Do I really need 90%+ isopropyl alcohol? ✔️Answer: Yes—higher concentration evaporates cleaner and helps weaken adhesive more effectively. ❓Question: Can I use a metal tool to pry the battery? ✔️Answer: Avoid sharp tools. Use non-sharp plastic tools; metal can slip and puncture a cell or short components. ❓Question: What should I do after installing the new battery? ✔️Answer: Do a full calibration cycle so the percentage reading becomes accurate. ❓Question: My MacBook still behaves weird after the swap—what now? ✔️Answer: Perform an SMC reset to address uncommon power/thermal/charging behavior.
