Replacement battery not taking a charge
The battery life on my Late 2010 MacAir 13" was poor so I decided to replace it.
I purchased the new battery from iFixit. The battery was for a 2011 model but claimed compatibility on the website.
The replacement went smoothly. However, the new battery would not take a charge.
I tried the SMC reset process a few times with no success.
I replaced with my old functioning battery and now that battery will no longer take a charge either.
The MagSafe charger is working on another MacBook of ours...so it's not the charger.
Thoughts? I feel I awakened some sleeping dog I shouldn't have bothered with.
