After replacing battery, laptop shuts down without warning
Hi, I recently replaced my mid 2012 13” MacBook Pro’s battery. The replacement went smoothly.
After doing so, my device will, without warning, shut down. This occurs both on battery power and while plugged in to the adapter. Sometimes, after I restart, the battery indicator says it was at the same power level as before. Other times, it will drop down to empty, even when it was previously reading ~30% or greater.
I have reset the SMC and zapped the PRAM. Attached is a screenshot of my coconutbattery results
Update (11/26/2018)
As mentioned above, here is the coconut battery data from my old battery (after an hour or two of charge)
Is this a good question?
