FAQs
Q: Is this the correct Apple MNUX3LL/A watch battery replacement?
This battery is intended for compatible Apple MNUX3LL/A watch and smartwatch models. Before ordering, compare your original battery part number, voltage, capacity, size, connector or contact position with the compatibility information on this page.
Q: What should I check before replacing a watch battery?
Check the battery code, voltage, capacity, physical dimensions, cable length, plug type or contact layout. Watch batteries are often small and similar in shape, so do not rely only on the device name if the battery part number is available.
Q: How do I find the correct battery for my watch?
The most reliable way is to check the battery code printed on your original battery. You can also check your watch model number, but the battery part number is usually more accurate because similar watch models may use different batteries.
Q: Is it safe to replace a swollen smartwatch battery?
A swollen battery should be handled with extra caution. Do not press, puncture, bend or reuse a swollen battery. If your watch screen is lifting or the back cover is pushed open, stop using the device and ask a qualified repair technician to inspect it.
Q: Will replacing the battery affect water resistance?
It may. Opening a watch or smartwatch can affect the original seal, gasket or adhesive. After battery replacement, water resistance is not guaranteed unless the watch is properly resealed and pressure-tested by a professional repair service.
