Replacement Smartwatch Battery, 3.8V, 390mAh

This replacement battery is engineered to restore full functionality to the Amazfit T-Rex smartwatch. The 390mAh Li-Polymer battery is designed to meet OEM specifications and deliver reliable performance for extended periods. With a rated voltage of 3.8V, this power cell is compatible with the original T-Rex model and provides consistent energy output throughout its operational life cycle. The battery supports the T-Rex's comprehensive feature set, including standard timekeeping, fitness tracking, and GPS navigation. Under typical usage conditions, users can expect approximately 20 days of battery life on a single charge. For extended operations, the watch offers a basic clock mode that delivers up to 66 days of continuous operation, while continuous GPS tracking consumes the battery in approximately 20 hours, depending on usage intensity and environmental conditions. This replacement component is ideal for facilities managing wearable device fleets, corporate wellness programs, or field operations teams that rely on Amazfit smartwatches for activity monitoring and GPS-enabled tracking. Industrial users benefit from the extended battery life that minimizes downtime and charging frequency, particularly valuable in remote work environments or continuous shift operations. The battery integrates seamlessly with the T-Rex's proprietary charging system and maintains compatibility with the device's full range of sensors and features. Organizations seeking to extend the operational lifespan of existing T-Rex units will find this replacement battery a cost-effective alternative to complete device replacement.
