Overview
The Sunshine SS-904B is a professional-grade battery activation and charging board specifically engineered for Android smartphones. When a Lithium-ion battery sits empty for too long, it enters a “sleep” mode that standard chargers cannot bypass. This board allows you to connect the battery directly to a power source to “wake it up” and bring it back to a functional voltage level. It is a must-have diagnostic tool for determining if a phone needs a new battery or just a professional activation.
Key Features
Massive Compatibility: Supports over 100+ Android models including Samsung, Huawei, Xiaomi, VIVO, OPPO, Meizu, and more.
One-Click Activation: Simply plug in the battery and press the activation button to start the revival process.
Intelligent Protection: Automatically limits the charging current to prevent overheating or damaging the battery cells.
LED Status Display: Real-time monitoring of current and voltage so you know exactly when the battery is ready to be put back in the phone.
Dual Power Input: Can be powered via a Micro-USB cable or connected directly to a DC Power Supply (like the Sugon or Sunshine 3005D).
