It's a bit hard to work out the problem - is it that you downloaded the zip file for the battery meter script from here? http://talk.maemo.org/showpost.php?p=872446&postcount=3

And now you have a zip file stored on your phone and you're wondering how to install it?

If so, it's a script for http://wiki.maemo.org/Queen_BeeCon_Widget .

But if you just want to keep an eye on what you're battery is doing, there's a couple of much easier to install apps in the repositores - eg battery-eye, battery graph.

...or have I completely misunderstood your question?


edit: by the way, are you into low level disk access hacking etc? should we be talking in assembler?!
