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.
