Macbook Air battery replacement. Any battery specialists out there? 19:28 - Nov 22 with 935 viewsBrynCartwright

This morning I replaced the original battery on my 2012 constructed Macbook Air with a £55 generic battery purchased off Amazon. So far so good, and saved at least £90 from using an Apple shop or service centre.

According to YouTube videos I should now "Calibrate the Power Management System" which involves charging the battery to the max, and then discharging to 0% and keeping it at 0% for 5 hours before charging back to full.

The Chinese battery instructions say I should not go below 2% power on the first discharge.

Who should I believe?

I know Gerwyn is throwing his arrows on ITV4, so do not want to distract you for too long. Just trying to establish how low to go with the battery discharge on my new MacBook battery.

Very easy Ebs. Lots of vids on You Tube showing what to do. Bought the Amazon recommended battery. The tool supplied with the battery to open the back was shit, so had to buy a decent tool off Ebay afterwards. Now though, after changing the battery this morning everything seems much better. Will pm you the part numbers in the morning when I am not so troubled by Pinotage.
