California Residents: Prop 65 WARNING

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.

Quality Parts For Quality Repairs

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.
