About Windows Laptop Batteries

Question about Windows laptop batteries.
This type of battery has a lot of contacts, do you know how to measure the voltage?

Check from the left there is a positive sign and the right side negative sign also, those are power pins, or terminals

There must be an enabling pin. If this pin isn’t low (connected to ground), the main terminals are not active.
