    Easy fit MacBook Air 11” battery replacement

    Posted by Glen Bertram on 20th Mar 2021

    Battery arrived promptly . Felt like quality product in smart packaging. Nice to have tools included. Followed simple video instructions and changed the battery in 20 minutes . Once calibrated works well giving around 4 hours use of browsing / email., which although not brilliant is a step up from the one hour I was getting out of the old battery . Would like to see UK option for recycling old battery.

    Functioning product so far with excellent instructional videos for installation

    Posted by Luke on 24th Sep 2020

    Product seems to be functioning without concern. Excellent straightforward videos demonstrating and explaining how to change Mac battery over. Only reason I can't yet offer 5 starts is I do not yet know the longevity of the battery no issues as 2 weeks.
