Hi All, I bought a replacement battery for my 15” MacBook Pro Retina (Early 2013) last month. (Manufacturing date March 11, 2021) I use iStat to monitor my system processes. After only 16 cycles, it now says “Service Required” and only 76% Health. The battery only lasts an hour to an hour and a half with normal usage. I’ve reset the SMC and the NVRAM already multiple times. I fully charged it, fully drained it multiple times. Could I have gotten a defective battery? The current Capacity is reporting at 6552 mAh. Thanks Edit Added Coconut Report
*Edit Fully charged battery now. Temp is 20 degrees lower, but life is still too short.
I was only streaming some video when I took the snapshot. Fan’s didn’t come on, and the CPU temp is right around 140 F. ( I was trying to fully drain the battery before a full recharge. The Second shot is a fully charged battery and the only app running is Safari and Plex. As a follow up, I submitted a ticket to iFixit today, and they’re sending a replacement battery. Great customer service, just not looking forward to removing fresh adhesive .. ugh.
