Yes, you can replace a MacBook Pro battery, but the method depends on your model year
Most MacBook Pro models from 2012 onwards have a battery that can be replaced, but Apple has made this progressively harder over time. Newer models (2016 and later) have batteries glued directly to the case, which means you cannot remove and swap it yourself without damaging the machine. Older models (2012–2015) have batteries held down with a few screws and are straightforward to replace at home. The year your MacBook was made determines whether you can do this yourself or need to take it to a repair shop.
Key Takeaways
- MacBook Pro models from 2012 to 2015 have user-replaceable batteries secured with screws and can be swapped at home with basic tools.
- Models from 2016 onwards have batteries glued to the case, so removing one risks cracking the enclosure and requires professional equipment.
- You can find your exact model year by clicking the Apple menu, selecting "About This Mac", and looking at the "Model Identifier".
- A replacement battery costs between $50 and $100 if you buy the part yourself, but professional replacement at an Apple Store or authorized repair shop typically costs $129 to $199.
- Before replacing the battery, back up your data and shut down your Mac completely, then disconnect the power adapter and wait a few minutes.
How to identify your MacBook Pro model year
Click the Apple menu in the top-left corner of your screen and select "About This Mac". Look for the line that says "Model Identifier"—it will read something like "MacBookPro11,1" or "MacBookPro15,1". The first number after "MacBookPro" tells you the generation. Models 11 through 13 are from 2012–2015 and have removable batteries. Models 13 and 15 from 2016 onwards (identified as "MacBookPro13,1" or higher) have glued batteries.
You can also check the year by looking at the bottom of the lid when the MacBook is closed. Older models have a removable battery compartment visible from the outside. Newer models have a sealed aluminum case with no visible battery door.
What you need to replace a battery yourself (2012–2015 models only)
You will need a P5 Pentalobe screwdriver (the five-pointed star-shaped tool Apple uses), a small Phillips head screwdriver, and a plastic spudger or guitar pick to gently pry connectors. A magnetic mat or small bowl helps keep screws organized so you do not lose them. You should also have a grounding strap or touch a metal part of the case frequently to avoid static discharge that could damage the logic board.
The replacement battery itself must match your exact model. Search for "MacBook Pro [your model year] battery" on Amazon or iFixit, and verify the part number matches what is printed on your current battery before ordering. Batteries typically cost $50 to $100 depending on capacity.
Step-by-step replacement for older MacBook Pro models
Step 1: Prepare your machine. Back up all your data to an external drive or cloud storage. Shut down your MacBook completely (not sleep mode). Unplug the power adapter and wait five minutes for any residual charge to drain.
Step 2: Remove the bottom case. Flip the MacBook over and use the P5 Pentalobe screwdriver to remove all screws from the bottom panel. Keep them in a safe place—they are small and straightforward to lose. Gently lift off the aluminum bottom case.
Step 3: Disconnect the battery connector. You will see the battery in the center of the machine, usually a black rectangular block with a white connector cable attached to the logic board. Use the plastic spudger to gently pry the white connector straight up and away from the board. Do not pull on the cable itself.
Step 4: Remove the old battery. The battery is held down by two or three screws on either side. Remove these screws with the Phillips head screwdriver. Lift the battery straight out of the case.
Step 5: Install the new battery. Place the new battery in the same position and find it with the screws you removed. Make sure it sits flat and does not shift. Reconnect the white connector by pressing it straight down onto the logic board until it clicks.
Step 6: Reassemble and test. Replace the bottom case and screw it back down. Power on your MacBook and check that the battery is recognized in System Preferences under "Battery". The new battery will show 0% charge initially and will need to charge fully before you use it normally.
Why 2016 and newer models require professional replacement
Starting with the 2016 redesign, Apple began gluing batteries directly to the aluminum case to save space and reduce weight. This design choice makes the battery impossible to remove without cracking or warping the enclosure. Attempting to pry out a glued battery will almost certainly damage the case, and the repair cost will exceed the cost of professional replacement.
Apple and authorized repair shops have specialized tools and heat guns that soften the adhesive without harming the aluminum. They can also may support the new battery is properly sealed and tested before you leave. If your 2016 or newer MacBook Pro needs a battery replacement, contact Apple Support or visit an Apple Store to schedule a repair.
Cost comparison: DIY versus professional repair
| Route | Cost | Time | Best for |
|---|---|---|---|
| DIY replacement (2012–2015 only) | $50–$100 for battery | 30–45 minutes | Comfortable with tools, want to save money |
| Apple Store or authorized shop | $129–$199 | Same-day or 3–5 days depending on location | Any model year, want warranty coverage |
| Third-party repair shop | $80–$150 | 1–3 days | Want lower cost than Apple, local service |
Signs your MacBook Pro battery needs replacement
A MacBook Pro battery typically lasts 300 to 500 full charge cycles before capacity drops noticeably. You will see the decline as reduced runtime—your machine might run for only two hours on a full charge when it used to run for five. You can check the current health of your battery by holding Option and clicking the battery icon in the menu bar. If it says "Service Recommended" or "Replace Now", the battery has degraded enough to warrant replacement.
Other signs include the battery swelling (the trackpad becomes hard to click or the bottom case bulges slightly), the machine shutting down suddenly even though the battery shows charge remaining, or the battery not charging past a certain percentage. Swelling is a safety concern and means you should stop using the machine and seek professional repair when ready.
Frequently Asked Questions
Can I replace a MacBook Pro battery without tools?
No. Even older models with removable batteries require a P5 Pentalobe screwdriver and a plastic spudger. These tools cost $10 to $20 together and are worth buying if you plan to do the work yourself. Attempting to pry open the case or disconnect the battery without proper tools risks stripping screws or damaging connectors.
What happens if I try to replace a glued battery myself?
You will likely crack the aluminum case or warp it enough that the lid no longer closes properly. Repairing the case costs more than professional battery replacement. If you damage the logic board while prying, the repair cost can exceed the value of the machine. Professional replacement is the safer choice for 2016 and newer models.
How long does a new battery last?
A replacement battery will last 300 to 500 charge cycles, the same as the original. This typically means three to five years of normal use. You can extend battery life by keeping your MacBook cool, avoiding full discharge cycles, and not leaving it plugged in constantly.
Will replacing the battery void my warranty?
If you do the replacement yourself on an older model, it will not void your warranty for other components, but Apple will not cover battery-related issues if something goes wrong during the swap. Professional replacement at an Apple Store or authorized shop comes with a one-year warranty on the battery itself.
Can I use any third-party battery, or does it have to be Apple?
Third-party batteries work and are often cheaper than Apple originals, but quality varies widely. Buy from reputable sellers like iFixit or Amazon that have customer reviews and return policies. Avoid extremely cheap batteries from unknown sellers—they may have lower capacity or fail quickly. Check the part number on your old battery and match it exactly on the replacement.
