Frequently Asked Questions

Can I replace my MacBook battery myself?

Yes — most MacBook battery replacements are very doable at home. Every battery we sell comes with access to a step-by-step installation video specific to your MacBook model. Most repairs take 20–40 minutes and require only basic tools. If you'd prefer to leave it to a professional, we also offer a mail-in Battery Installation Service.

How easy is it to replace my MacBook Pro battery myself?

Battery replacements for most MacBook Pros released after 2011 require a bit of care and patience. From 2012, Apple introduced the MacBook Pro Retina with a glued-down battery, meaning replacements through to the 2020 models require adhesive removal techniques and the right tools — but they're definitely doable.

From 2021 onward, MacBook Pro batteries are held in place with stretch-release adhesive pull tabs that anyone can remove without special chemicals or tools. The rest of the process involves handling screws, connectors, and cables, and is generally straightforward.

How easy is it to replace my MacBook Air battery myself?

MacBook Air battery replacements are generally easier than MacBook Pro. Models released before 2018 simply require removing the bottom case, disconnecting the battery, and unscrewing a few screws.

From 2018 onward, the battery is held down with adhesive pull tabs — still very manageable. All models involve handling screws, connectors, cables, and clips, which our install videos walk you through step by step.

How much does it cost to replace a MacBook battery?

Replacing your MacBook battery with a Macfixit replacement battery is significantly cheaper than Apple's out-of-warranty battery service. Our DIY batteries let you do the same repair for a fraction of the cost — and if you add our mail-in installation service, it's still well below Apple's price.
