no. quite opposite. cheap knock-off batteries will show you output all the time which means they are dangerous to install and use.[br]

battery only outputs voltage if its SYSTEM_DETECT pin is connected to ground. if you cant test it in device you can emulate that by shorting pin 1 on bmc data flex cable to ground, so basically short first and last pins on bmc flex cable and measure battery voltage. [br]

battery only outputs voltage if its SYSTEM_DETECT pin is connected to ground. also since 2018 all macbooks require an active voltage supply to activate the battery which means if you connect the battery it wont output voltage untill you connect the charging cable (whis will turn on transistor which will be kept on by battery afterwards)[br]

fully discharged battery wont show output but it will accept charge if it is connected to logicboard.[br]
