Apple Watch battery replacement costs between $79 and $99 at an Apple Store, depending on your watch model and whether it's still under warranty.

If your watch is covered by AppleCare+, the replacement is free. If you're out of warranty and out of AppleCare+, you'll pay the full service fee. Apple doesn't sell batteries separately to consumers — replacement is a service-only transaction, meaning you hand over the watch and Apple handles the entire job.

The price doesn't include shipping if you mail the watch in, though Apple offers mail-in service through their website. Some authorized Apple resellers charge the same amount, but prices can vary slightly by location and reseller. Third-party repair shops often charge less — typically $40 to $60 — but this voids any remaining warranty and the quality of the repair depends entirely on the shop.

  • AppleCare+ covers battery replacement at no cost if you purchased the plan within 60 days of buying your watch.
  • Mail-in service through Apple's website is available if you don't have a nearby store, though it takes one to two weeks.

  • Battery replacement typically takes same-day or next-day service at Apple Stores, but mail-in service takes longer.

Pricing by Apple Watch model

Apple charges different amounts based on which generation and size of watch you own. Series 9, Ultra 2, and SE models fall into one price tier, while older models like Series 8 and Series 7 may fall into another. The difference is usually $10 to $20 between the oldest and newest models.

You can check the exact price for your specific watch by visiting Apple's service pricing page or calling your local Apple Store with your watch model and generation number. The model and generation are printed on the back of the watch case. If you're unsure which generation you have, open the Watch app on your paired iPhone, go to General, then About — the model name and software version appear there.

What AppleCare+ covers

AppleCare+ is a protection plan you purchase separately, usually at the time you buy the watch. It costs between $79 and $99 depending on the model, and it lasts two years. During that time, battery replacement is covered at no cost as long as the battery has degraded to 80 percent capacity or less — Apple's standard for a battery that needs replacement.

AppleCare+ also covers accidental damage (with a deductible of $79 to $99 per incident), hardware failures, and technical support. If you didn't buy AppleCare+ when you purchased your watch, you can still add it within 60 days of purchase. After that window closes, you cannot add it later.

How to start a battery replacement at Apple

Visit apple.com/support, select your watch model, and choose "Battery Service" from the menu. You can then book a Genius Bar appointment at a nearby Apple Store, or request mail-in service. If you choose in-store service, bring your watch and the charger. You don't need to bring the original box or any other accessories.

For mail-in service, Apple will email you a prepaid shipping label. Pack the watch securely in a padded envelope or small box, and drop it at any carrier location. Apple typically completes the repair and ships it back within five to seven business days, though this can vary during busy periods. You'll receive an email when the repair is complete and when it ships back to you.

Third-party repair shops and their trade-offs

Independent repair shops and electronics retailers like Best Buy Geek Squad offer Apple Watch battery replacement for $40 to $60. The lower price is appealing, but there are real downsides. Any remaining manufacturer warranty is voided the moment a non-Apple technician opens the watch. If something goes wrong during the repair — a cracked screen, a seal that doesn't hold, a battery that fails early — you have no recourse with Apple.

Third-party shops also use aftermarket batteries, which may not hold a charge as long as Apple's original batteries. Some shops are reputable and do careful work, but quality varies widely. If your watch is still under warranty or AppleCare+, using a third-party shop will void that coverage entirely. Only consider this route if your watch is old, out of warranty, and you're willing to accept the risk.

Signs your Apple Watch battery needs replacement

A battery that drains much faster than it used to is the clearest sign. If your watch used to last a full day and now dies by afternoon, or if it shuts down at 20 percent battery, the battery is degrading. You can check the battery's health by opening the Watch app on your iPhone, going to General, then About, and looking at the Battery Health percentage.

Apple considers a battery ready for replacement when it drops to 80 percent of its original capacity. At that point, the battery can no longer hold a full charge reliably. If your battery is at 85 or 90 percent, you may not notice much difference yet, but it will continue to degrade. Replacing it now means you won't face a dead watch in a few months.

Turnaround time and what to expect

At an Apple Store, battery replacement usually takes one to two hours if you have a Genius Bar appointment. You can often wait in the store, or you can leave and come back. The technician will power off your watch, remove the back case, disconnect the old battery, install the new one, and test it before reassembling.

Mail-in service takes longer. After you ship the watch, Apple receives it, diagnoses it, performs the repair, tests it, and ships it back. The entire process typically takes five to seven business days, though it can stretch to two weeks during peak periods. You'll lose access to your watch during this time, so plan accordingly if you rely on it for fitness tracking or notifications.

Frequently Asked Questions

Can I replace the battery myself?

Apple Watch batteries are glued in place and require specialized tools to remove without damaging the watch case or screen. The back case is sealed with adhesive, not screws. Attempting a DIY replacement almost always results in a cracked screen or a case that no longer holds a water-tight seal. It's not a realistic option for most people.

Will Apple replace the battery if it's still under the one-year warranty?

Yes, if the battery has degraded to 80 percent capacity or less, Apple will replace it at no cost under the standard one-year warranty. You don't need AppleCare+ for this. Bring your watch to an Apple Store or request mail-in service, and explain that the battery is draining faster than normal.

What happens to my data when Apple replaces the battery?

Your data stays on the watch. Apple doesn't erase the watch during a battery replacement — they straightforward swap out the battery and reassemble it. Your apps, activity history, and settings remain exactly as they were. The watch will be fully functional when you get it back.

Is it worth buying AppleCare+ just for battery replacement?

AppleCare+ costs $79 to $99 and lasts two years. If you plan to keep your watch for the full two years, the plan covers not just battery replacement but also accidental damage and hardware failures. One accidental drop that cracks the screen could cost $200 to $300 to repair — AppleCare+ would cover it for $79 to $99. Whether it's worth it depends on how carefully you handle your devices.

Can I get a replacement watch instead of a battery replacement?

Only if the watch is defective beyond repair. A degraded battery alone doesn't may have access to for a full device replacement — Apple will replace the battery instead. If the watch has multiple hardware failures or the case is damaged, Apple may offer a replacement, but this is rare and requires an in-store evaluation.
