Hello! I replaced the trackpad cable on my Early 2015 13” MacBook with Retina Display because my keyboard and trackpad were not responsive. This replacement fixed the issue, however, now the battery is not holding charge. When I connect it to the charger, it says there is 67% battery but when I remove it from the charger it dies and I have to plug it in to reconnect. Why isn’t my computer recognizing the charge on the battery? Is this purely coincidental or did I do something during the repair? I disconnected the battery before replacing the trackpad cable and reconnected it before reassembling the device. Any guidance would be appreciated!

When I run diagnostics through the MacOS I was given the note that the battery condition is “replace now” So, I guess my question is, Is there something that I may have done during the repair that would have caused this message to be triggered without an actual faulty battery? I know that a typical cycle of the Macbook battery is 1000 and I am just over that so it’s probable the battery needs replaced now, just bummed that this happened to occur as soon as I replaced the trackpad cable. Would have been preferable to replace the battery then the cable, but here we are. Is my only option to replace the battery now?
You have a three-fer! Yes you need a new battery as the cycle count is over 1,000! Determine battery cycle count for Mac notebooks as you can see your well over the expected lifespan of the battery. But! You may have a second issue! The SMC charging logic may be damaged as well! Until you replace the battery you won’t know for sure. And lastly the third! Is your MagSafe charger might have been the cause of your SMC logic getting damaged. ● Don’t Replace Your MacBook Charger With a Cheap Knockoff ● OEM MagSafe Chargers vs Cheap Imposters: Teardown for Truth ● Lacking safety features, cheap MacBook chargers create big sparks ● FAKE Magsafe MacBook Chargers on eBay - Watch before buying a Mac Charger Make sure you have a REAL Apple charger by getting directly from Apple Apple 60W MagSafe 2 Power Adapter (MacBook Pro with 13-inch Retina display)
