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.

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.

iFixit's MacBook replacement parts are meticulously tested and backed by our Quality Guarantee. We've spent over a decade scrutinizing component manufacturers and aftermarket suppliers so that you can trust the parts you receive.
