Released in 2015, the Moto 360 2nd Gen 42mm was one of the most iconic Android Wear smartwatches, featuring a premium round 42mm display, stainless steel case, Qualcomm Snapdragon 400 processor, and the signature “flat tire” ambient light sensor at the bottom of the screen. After 8-10 years of use, the original battery capacity has likely degraded significantly — a common issue with aging smartwatches. This Li-ion Polymer battery restores the full 375mAh rated capacity (400mAh typical), bringing back the reliable daily performance this classic smartwatch was designed for. Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE, RoHS, and UN38.3 certified. Designed for Classic Smartwatch Restoration: The Moto 360 2nd Gen 42mm was praised for its premium design — stainless steel case, genuine leather or metal bands, and a vibrant OLED display with an always-on mode. However, after years of use, battery degradation is the most common issue. Typical symptoms include: the watch not lasting through a full day, needing to be placed on the charger by evening, unexpected shutdowns at 20-30% battery, difficulty powering on without the charger connected, or visible battery swelling. This replacement battery restores the original performance, allowing you to continue wearing this classic smartwatch instead of replacing it with a newer model. For Moto 360 2nd Gen 42mm battery replacement, professional installation is recommended as the watch is sealed with adhesive and requires careful opening to avoid damaging the OLED display or the heart rate sensor. Compatibility Note: Fits Moto 360 2nd Gen 42mm (FW3S / SNN5971A) only. Please confirm your watch size and model before ordering. This battery is NOT compatible with the Moto 360 2nd Gen 46mm, original Moto 360 1st Gen, Moto 360 Sport, or other smartwatches.
