In an instance that ACPI reports multiple batteries, having an option to specify which one to use could be very useful.
For example, I am using Logitech Unifying Receiver, and it reports back battery information of my keyboard and mouse (wrong information I might add, as can be seen on the screenshot)
In this case, those two come before my actual laptop battery (Battery 2), and because of this, I always get the 0% state.
I have added the option LP_BATTERY_ID, with the default of 0, so that users can specify which battery they want to read.
