% Charged--Two Readings: Why the Difference?

[W. Watson]

I have a Xantera 600HD Power Pack and decided to try it out for a situation
I might want to use it in. I wanted to see how long I could run a VCR and
Epson S3 computer projector. I put in a tape 30 minute long and ran the two
devices for 20 minutes. At the end of that time, I unplugged the two devices
and turned off the PP. When I pressed the % charge button it showed 10%.
After about 30 minutes I thought I'd charge up the battery and redo the test
in a slightly different way. However, I decided to check the % charge and
found it was now 50%. How does one explain this? BTW the two devices were
doing just fine when I turned them off.

Batteries bounce back a little after a heavy discharge and those meters are
not good for much.

How does that simple, descriptive name suggest the detailed performance
characteristics of some pile of fucking shit you bought somewhere = " on

He must have. It's rare to get an answer from him without the
vituperation.

Is there a meter that better reads out the charge more accurately?

When it come to percentage of charge left in the battery any meter is really
just a guess.

They take the discharge curve of the battery at the devices rated current
and assign values on the curve until the device wont function.
Many things disrupt the accuracy.
