The 2UUL BT05 Disassembly-Free Battery Activation Board lets you test and activate iPhone and Android batteries without opening the battery protection board. Built for technicians handling dead phone cases from over-discharge, long idle storage, or low-voltage lockup, this board restores normal charging behavior fast. It works across iPhone 8 through the 17 Pro Max lineup and popular Android brands including Samsung, Huawei, Xiaomi, Oppo, and Vivo, so one tool covers most of your repair bench. A built-in digital display shows real-time voltage and current while the battery activates, so you confirm the fix is working instead of guessing. Compact and simple to run on 5V/2A input, it fits into daily battery diagnostics, after-sales checks, and second-hand phone refurbishment work.
