I replaced the battery of my mid-2010 MacBook Pro 15". It takes ages to charge, “20:00 until full”. System Information shows a charge rate of 288mA. I once got it to charge at a better rate, by draining the battery completely until the system shut off and then charging. Charge rate was around 5000mA, after this charge cycle, it’s back to the old slow charging. I already tried NVRAM and SMC resets, but those don’t help. Any ideas?
Hi Sander, Sounds as though you got a defective battery. I take it the reason you replaced the battery was because it didn’t hold a charge anymore? Try repairing your disk permissions first, then performing a SMC reset. See what that does.
Hi, I have the same issue on my MacBook Pro early 2011. I change the dead battery with another apple’s original one, after some cycles the charge is very very slow, something like 12,40 hours to full charge. I try all the possible resets, in Apple Store the Genius try to change the battery with another one and the mag safe connector and the last answer was “you must change the logical board”. I can’t repeat what I told him… Are there any other possible solutions? Thank you for your time and sorry for my english…
Resetting NVRAM worked for me :) Thanks!
