So… mAh is a bit of a useless number. Watt hours is a multiplication of amps and volts. If a product tells you the amp hours, that’s only one half of the equation.

If you can find the voltage on your battery, you can use the following format to get a rough estimate of charges.

mAh÷1000×volts/55wh.

They’re functionally identical. I bought another when I upgraded to the amd board and it works fine.
