Chosen Solution
A few months ago, during a trip to Japan, my MacBook pro stopped charging with a 45W adapter. I went to a local store and bought a higher 60W adapter. Although the battery worked fine for a few days of use, my MacBook pro’s battery stopped charging again. A week ago, I decided to fix the issue. Initially I tried updating the OS, which I restored later, but learned my lesson when the battery cut off during the installation and corrupted the drive. Later on, I replaced my battery but mistakenly with an A1493 battery, which I replaced with the proper A1502 battery for 2015 model macbooks. There is no liquid damage. The Macbook Pro stays fixed at 42.1% but for a few seconds charged to 42.2% with 0.2W of input. The battery indicator at the top says “Replace Now” as well as the diagnostics from boot. The MacBook pro shuts off if removed from the power adapter, just as it did for the previous batteries. Should I replace the battery again, or could there be an issue with the power adapter or logic board? I have tried resetting the SMC and unplugging and replugging the battery connector. Here are the results for coconutbattery:
Edit: Both chargers are genuine apple products. I thought that they or the Japanese AC sockets might have caused the issue but they are now ruled out. I am still in the return window so battery replacement is still an option. I am wondering if battery replacement is futile and if there might be damage to the logic board.
You likely had a double whammy here! First you need to be very careful on what you buy for a MagSafe charger as often times its a fake! Lacking safety features, cheap MacBook chargers create big sparks. These chargers can damage your system as well as start a fire. Here’s what it does to your system What does knockoff charger do to Macbook Pro Retina? The mistake with the batteries likely didn’t damage anything more.
