Yes. iFixit provides free step-by-step repair guides for every Apple Watch generation and sells DIY replacement batteries plus adhesives and tools. Apple Watch battery replacement is a bit more delicate than phones because the display is sealed to the case and must be carefully heated and lifted to access the battery. If you are only replacing the battery be extra cautious to not damage the Apple Watch's OLED display, which is more expensive than other types of displays like LCDs.

iFixit sells Fix Kits for some models. These kits include all the necessary tools and parts to replace your battery. If a Fix Kit is not available for your watch model, plan on obtaining opening picks, an iOpener (or equivalent heat source), an iFlex (or other flexible device opening tool), tweezers, and a small tripoint screwdriver depending on your model. If you get stuck, iFixit's community of fixers can help.

Doing it yourself typically saves $49–$79 compared to Apple’s out-of-warranty service (usually $99 for supported models). Most Apple Watch batteries on iFixit cost between $20–$37 depending on size and series, while the Apple Watch Ultra battery is about $45. See model-by-model pricing and estimated savings below.

^ Apple’s typical out-of-warranty battery service fee for supported Apple Watch models is about $99 as of September 2025. Older “vintage” or “obsolete” models may not be serviced by Apple; check availability via Apple’s estimate tool.

Plan for at least 45 minutes to 2 hours, depending on the watch model and your experience. Recent models like Series 7/8 are commonly 30–50 minutes; Apple Watch Ultra battery service can take 1–2 hours. You’ll be handling adhesive, tiny ZIF connectors, and the display. Take your time and protect the display and cables. If you run into trouble, iFixit’s community of fixers is there to help.
