Battery Monitor documentation

[etski]

I've searched high and low and can't find any documentation on the Battery Monitor that is included on many of the roms. Some fields are fairly obvious and the most important ones are clearly charge current and discharge current, but I was wondering if anyone knows more about some of the other fields.

The first value MainBatteryID changes while using just a single battery. Any idea why? Does this mean I have an unstable battery? I thought this would be helpful in tracking perfomance on different batteries, but, at least on the battery in my phone now, has unstable readings. Why?

Any idea what CBI stands for?

How about temperature_AD?

Does anybodys' Temperature value actually change? Mine always shows 30C no matter how hot the phone feels!

ChargeCurrent sometimes reads a value, occassionally 1 or 2 mA, even with no charger connected! usually 0, but sometimes non-zero.....?

Nice tool, but would love to know more! Can anybody help?
