One Year Guarantee

Right For The Environment & Your Wallet

It’s not just more sustainable—it’s cheaper, too. Replacing your MacBook battery with an iFixit Fix Kit can save you a considerable amount compared to Apple’s out-of-warranty service—depending on your model.

Good Battery = Good Experience

All laptop batteries wear out after about 18 months. An aging battery can cause problems like overheating, performance slowdowns, and unexpected shutdowns. Swapping in a fresh one restores reliable power—so you can focus on what matters.

The battery was great. It’s just that the shipping was the problem. It took 9 days to go 74miles from where it shipped from to my house. Free shipping or not that was way to far long of a time.

MacBook Pro 15" Unibody (Mid 2009-Mid 2010) Battery | New / Part Only

The position of the tabs for the three screws holding the battery to the case were slightly wider - just a couple of millimeters - than the original battery which meant it was very difficult to align it with the screw holes in the case so the screws would not go straight into the holes. Had to use pliers to force the outer ones to tightened down. The battery is working just fine.
