Yes, you can replace a MacBook battery, but the method depends on your model and year

Most MacBooks have a battery you can remove and install yourself, but some newer models have the battery glued or soldered to the case, making replacement much harder. If your MacBook is from 2015 or earlier, you can almost certainly do it with basic tools. If it's from 2016 onward, check your specific model first—some allow user replacement, others do not. Even when replacement is possible, you'll need the right screwdrivers, a way to disconnect the battery safely, and patience to avoid damaging the trackpad or keyboard underneath.

The entire process takes 30 minutes to two hours depending on your model. A replacement battery costs between $50 and $150 from third-party sellers, or you can pay Apple $129 to $199 for professional replacement if your model doesn't support user removal.

Key Takeaways

  • MacBooks made before 2015 typically have user-replaceable batteries held in with a few screws and a straightforward connector.
  • Newer MacBooks (2016 and later) often have batteries glued down, requiring professional removal or significant disassembly.
  • You will need a pentalobe screwdriver (the five-pointed Apple tool), a spudger or plastic pry tool, and ideally an anti-static wrist strap to avoid damaging components.
  • Battery replacement takes 30 minutes to two hours depending on your model, and the battery itself costs between $50 and $150 from third-party sellers.
  • If your battery is still under warranty or your MacBook is recent, Apple's repair program may be cheaper than buying the part yourself.

Check your MacBook model and year first

Open the Apple menu in the top-left corner of your screen, click About This Mac, and look at the model name and year. Write this down—you'll need it to find the exact battery part number and removal instructions for your machine.

Once you have the model, search "[Your MacBook model] battery replacement" on YouTube or iFixit.com. Watch a video of someone removing the battery from your exact model. If the battery is glued down and requires heating tools or significant disassembly, you may decide professional replacement is worth the cost. If it's held in with two or three screws and a straightforward connector, you can do it yourself.

Gather the right tools and parts

You will need a pentalobe screwdriver (the five-pointed bit Apple uses), which costs $5 to $15 and is not included in most basic tool kits. You'll also need a spudger or thin plastic pry tool to disconnect the battery connector without damaging it—a guitar pick or old credit card works in a pinch, but a proper spudger is safer. An anti-static wrist strap ($5 to $10) protects your MacBook's logic board from static electricity damage, though it's optional if you touch the metal case frequently to ground yourself.

Order the replacement battery before you start. Search for your MacBook model number plus "battery" on Amazon or eBay. Prices range from $50 to $150 depending on capacity. Avoid the cheapest listings—they are often counterfeit or low-capacity. Look for batteries with at least 50 reviews and an average rating above 4 stars. Some sellers include a tool kit with the battery, which saves money.

Power down and disconnect everything safely

Shut down your MacBook completely—do not just close the lid or put it to sleep. Unplug the power adapter and wait five minutes for the machine to cool. If your battery is swollen or visibly damaged, do not proceed; take it to Apple or a repair shop instead, as swollen batteries can catch fire.

Flip the MacBook over so the bottom case is facing up. If your model has a pull-tab or latch holding the bottom case, use it. Otherwise, use your pentalobe screwdriver to remove all the screws around the perimeter. Keep the screws in a small container or tape them to a piece of paper in the order you removed them—different screw lengths go in different holes, and putting them back wrong can damage the case.

Disconnect the battery connector before touching anything else

Once the bottom case is off, locate the battery connector—it's a small plug with a white or black plastic housing, usually near the edge of the battery. This is the most important step: disconnect the battery first, before you remove any screws holding the battery itself. This cuts power to the board and prevents accidental short circuits while you work.

Use your spudger to gently pry the connector straight up and away from the socket. Do not pull at an angle or yank on the cable. If it does not move after gentle pressure, look for a small clip or tab you may have missed. Once the connector is free, you can safely remove the battery screws and lift the old battery out.

Install the new battery and reconnect

Slide the new battery into the space where the old one was, making sure it sits flat and level. Screw it down using the same screw holes—use the screws you removed earlier, in the same positions. Do not over-tighten; stop when the screw is snug.

Reconnect the battery connector by aligning it with the socket and pressing straight down until you hear or feel a click. Reconnect the bottom case by replacing all the screws in their original holes. Power on your MacBook and check the battery status in the menu bar—it should show the new battery at 100% capacity (or close to it) within a few minutes.

What to do if the battery is glued or soldered

If your model has the battery glued to the case or soldered to the logic board, user replacement is not practical. Removing it requires heating tools, specialized pry techniques, and risk of damaging the trackpad or keyboard. In this case, contact Apple or an authorized repair shop.

Apple's out-of-warranty battery replacement costs between $129 and $199 depending on your MacBook model. Independent repair shops often charge $80 to $150 for labor plus the cost of the battery. If your MacBook is still under warranty or covered by AppleCare+, the repair may be free or heavily discounted—check your coverage before paying out of pocket.

Frequently Asked Questions

How long does a MacBook battery last before I need to replace it?

Apple rates most MacBook batteries for 1,000 charge cycles, which typically means three to five years of normal use. You can check your battery's current health by holding Option and clicking the battery icon in the menu bar. If it says "Service Recommended" or "Replace Now," replacement is due.

Can I use a third-party battery instead of an Apple battery?

Yes. Third-party batteries are cheaper and work fine in most cases, though they may not last as long or hold charge as reliably as genuine Apple batteries. Buy from sellers with strong reviews and avoid suspiciously cheap listings. If the battery fails, you can replace it again without voiding anything—your MacBook's warranty is already expired if the battery needs replacement.

What if I damage the battery connector while removing it?

If the connector is cracked or the pins are bent, the battery will not charge. You can sometimes bend pins back with a magnifying glass and tweezers, but if the plastic housing is broken, you need a new logic board or professional repair. This is why gentle, straight-up pressure on the connector is critical.

Do I need to calibrate the new battery after installation?

No. Modern MacBooks calibrate the battery automatically over the first few charge cycles. Just use your MacBook normally—charge it fully, then let it drain to near-empty a few times, and the system will learn the battery's capacity.

Is it safe to replace the battery myself if I have never done it before?

Yes, if your model has a user-replaceable battery. Watch a video of your exact model first, work slowly, and disconnect the battery before touching anything else. The main risks are dropping screws into the case or pulling the connector at an angle. If you feel uncomfortable at any point, stop and take it to a repair shop instead.
