battery status can't handle with multiple batteries simultaneously

Thank you for taking the time to report this bug and helping to make BatteryStatus better.
Could you try, please, new version 0.1.1 from PPA ( https://edge.launchpad.net/~iaz/+archive/battery-status ). This is how it should works now:
one (any) battery without AC - correctly;
one (any) battery with AC - correctly;
both batteries without AC - correctly, but will be reported status information about battery which has been plugged first;
both batteries with AC - the same thing: it should works correctly, but will be reported status information about battery which has been plugged first.
Let me know, if I'm right, and correct me, if I'm wrong. Then we can keep moving on :-)

Ok, installed 0.1.1, rebooted and tested. Unfortunately the applet is not working like you intend. Here's what it does:

One (any) battery without AC: Correct.
One (any) battery with AC: Correct.
Both batteries without or without AC: Icon is frozen and left clicking on the applet does absolutely nothing. Nothing pops up. Very strange?

How about this - try to run applet in window debug mode (from terminal):
$ /usr/lib/battery-status/battery-status --window
and paste here some logs/tracebacks/warnings/messages/etc if such appears.

Here's the output:

~ -> /usr/lib/battery-status/battery-status --window

Looks like a typo. If I replace 'battery_devices' with 'power_battery_devices' it seems to work.

It would be nice if it tried to select the battery that it displays information for based on the one that is currently discharging. Of course, the ideal scenario would be to display information about both batteries, like the default battery status indicator that ships with Lucid :)

Yep, that's it. So now, as I've supposed, with both batteries information available only for one battery, right?
Then the problem is: battery status just can't handle with multiple batteries simultaneously (so I'll change text of report a little bit) - I agree, that this feature should be implemented (as correctly as possible), but this requires some essential modifications of code, so I think that this bug will be fixed in a couple weeks, not earlier.
