mAh is a measure of the capacity to deliver that voltage.
You know a battery doesn't last forever. If you suck a lot of current
out of it, it will empty sooner. If you suck only a little current, it
will last longer.
mAh is "milli Amp Hours", so a 1500 mAh cell can deliver 1500 mA for one
hour, or 150 mA for 10 hours, etc.
In reality it is not a perfectly linear relationship, but it is a useful
number for reference and comparison.

I have a similar one marked as 1500 mAh that gives my Galaxy S a 50-60%
charge. So since this is marked 2800 mAh, I'd guess it would give a
full charge. And it's only $11, including shipping to Israel.
What does the mAh have to do with a full charge? I though that was a volt thing.
