I was wondering if there's an easy way I could find out the mAh for my laptop battery, It's a Lenovo Yoga 12 and it states on the manufacturers website that the battery is a Li-Polymer 8-cell 47Wh but there's no information on the battery voltage so I can't convert the 47Wh to mAh. I' like to know because I'm buying a powerpack and want to know the mAh for comparison.

You can use HWMonitor -
It will give you detailed battery info:
BatteryInfoView from trustful source who wrote a lot of useful and unique utilities.(Not affiliated, just happy user :) )
It doesn't requiring installation, works as standalone program.
If you're on linux, then directory /sys/class/power_supply/BAT0 will tell the same info (but in linux way) or if you have installed package upower then use
upower -i /org/freedesktop/UPower/devices/battery_BAT0 to see result in human readable text
