The Sunshine SS-904A Upgraded activation and battery charging board is a high-performance universal solution for GSM service workshops,
designed for the rapid reactivation of deeply discharged batteries and testing batteries for over 500 Android models.
The module automatically recognizes positive and negative polarity thanks to the integrated smart circuit, preventing short circuits and ensuring
a secure snap-on type connection. With a stabilized 4.2V output, advanced overload protection with automatic shutdown, and intuitive LED
status indicators, the device automatically stops power once the battery is fully charged,
extending cell life and optimizing workflow in the lab.
