Apple Watch battery replacement costs between $79 and $99 depending on the model, plus tax

Apple charges a flat rate for out-of-warranty battery replacement at any Apple Store or through mail-in service. The exact price depends on which Apple Watch model you own — Series 9, Ultra, SE, and older generations each have different replacement costs. You cannot buy the battery alone and install it yourself; Apple does not sell individual batteries to consumers, and the watch is sealed in a way that makes DIY replacement impractical.

If your watch is still under the one-year limited warranty and the battery is genuinely defective (holding less than 80 percent of its original capacity), Apple replaces it at no cost. Once that year is up, you pay the replacement fee. AppleCare+ extends coverage to two years and covers battery replacement as part of accidental damage protection, though you would still pay the service fee if the battery failed from normal use.

Key Takeaways

  • Out-of-warranty battery replacement costs $79 to $99 depending on your watch model, and Apple is the only authorized source.
  • Batteries under one-year warranty are replaced free if they fail to hold a normal charge, but you must prove the watch is within that window.
  • AppleCare+ covers battery replacement as part of its two-year protection plan, though the exact cost depends on your watch model.
  • Mail-in service takes about one to two weeks; in-store replacement at an Apple Store is usually faster but depends on parts availability.

Breakdown by Apple Watch model

Apple Watch Series 9 and Ultra models cost $99 for battery replacement. Series 8, Series 7, and SE (second generation) cost $79. Older models like Series 6, Series 5, and the original SE also cost $79. The price difference reflects the size and capacity of the battery, not the age of the watch.

Before you pay, confirm your exact model by opening the Watch app on your paired iPhone, tapping the General tab, and checking the model name. You can also look at the back of the watch itself — it lists the model. Bring this information when you contact Apple or visit a store, because quoting the wrong model can lead to an incorrect price estimate.

How to start a battery replacement

Visit an Apple Store in person or go to apple.com and select "Repair" under your watch model. If you choose mail-in service, Apple sends you a prepaid shipping label. You pack the watch and drop it off at any UPS location. The watch ships to an Apple repair facility, where technicians replace the battery and run diagnostics. The whole process takes about one to two weeks from the day Apple receives it.

In-store replacement is faster if your local Apple Store has the battery in stock — sometimes same-day, sometimes a few days. Call ahead to check availability before you go. If the store does not have the battery, they can order it and you pick up the watch when it arrives, which usually takes three to five business days.

What happens if the battery is still under warranty

Apple's one-year limited warranty covers defective batteries at no cost. A defective battery is one that no longer holds a normal charge — typically less than 80 percent of its original capacity within the first year. You do not have to pay the $79 or $99 fee if the watch is within that window and the battery genuinely failed from a manufacturing defect, not from physical damage or liquid exposure.

To claim warranty coverage, bring your watch and proof of purchase (receipt, order confirmation, or your Apple ID account) to an Apple Store, or start a mail-in repair through apple.com. Apple will test the battery and confirm whether it qualifies as defective. If it does, replacement is free. If the battery is straightforward worn from normal use after one year, you pay the standard replacement fee.

AppleCare+ and battery coverage

AppleCare+ extends your coverage to two years and includes battery replacement if the battery degrades below 80 percent capacity. The cost of AppleCare+ varies by watch model — typically $40 to $100 for the full two-year plan, paid upfront or monthly. You must purchase it within 60 days of buying the watch.

With AppleCare+, battery replacement is covered as part of the plan at no additional cost. You still have to initiate the repair through Apple, but you do not pay the $79 or $99 fee. AppleCare+ also covers accidental damage like drops and water damage, which the standard warranty does not.

Why Apple Watch batteries cannot be replaced at home

Apple Watch cases are sealed with adhesive, not screws. Opening the case yourself requires specialized tools and risks damaging the display, the internal components, and the water resistance seal. Even if you managed to open it, the battery is soldered to the logic board in many models, meaning it cannot straightforward be unplugged and swapped out. Third-party repair shops can do it, but they void any remaining warranty coverage and may not have genuine Apple batteries.

Apple's sealed design is intentional — it allows the watch to be thinner and more water-resistant than it would be with a user-replaceable battery. The trade-off is that you must go through Apple or an authorized repair shop when the battery fails.

Third-party repair shops and warranty risk

Some independent repair shops offer Apple Watch battery replacement for less than Apple's price, sometimes $40 to $60. However, using a third-party shop voids any remaining manufacturer warranty and may use non-genuine batteries that do not perform as well or last as long. If something goes wrong after a third-party repair, Apple will not cover it under warranty.

If cost is a concern, check whether your watch is still under the one-year limited warranty first — that replacement is free. If it is not, compare the cost of AppleCare+ (if you can still purchase it) against the one-time $79 or $99 replacement fee. For most people, paying Apple directly is the safer choice because you get a genuine battery and a warranty on the repair itself.

Frequently Asked Questions

How long does an Apple Watch battery last before it needs replacement?

Apple Watch batteries are designed to retain 80 percent of their original capacity after 1,000 charge cycles, which typically takes two to three years of daily use. Most users notice the battery draining faster around year two or three. You do not have to replace it when ready when it starts to degrade — you can keep using it and just charge it more often until you decide to replace it.

Can I replace the battery myself with a kit from Amazon or eBay?

Kits exist, but they are risky. Opening the watch yourself can damage the display or the water resistance seal, and most kits include non-genuine batteries. If something breaks during the repair, you cannot return to Apple for help. The $79 to $99 Apple charges is worth the may provide that the repair is done correctly.

Does AppleCare+ cover a battery that just wears out from normal use?

Yes. AppleCare+ covers battery replacement if the battery degrades below 80 percent capacity, regardless of whether it is a manufacturing defect or normal wear. You do not pay the $79 or $99 fee — it is included in your AppleCare+ plan.

What if my Apple Watch is out of warranty and I do not have AppleCare+?

You pay the standard replacement fee: $79 for Series 8, SE, and older models, or $99 for Series 9 and Ultra. You can do this through an Apple Store or by mail-in service on apple.com. There is no other way to get an official replacement without paying.

How long does mail-in battery replacement take?

From the moment you ship the watch to when it arrives back at your door usually takes one to two weeks. Apple provides a prepaid UPS label, and you can track the shipment. During busy periods, it may take longer. In-store replacement is faster if your local Apple Store has the battery in stock.
