Discharge estimate is wrong when using APC ups

upower -d output
Description of problem:
I have an APC Back-UPS RS 800.
upower detacts the UPS without any apparent issues.
I've noticed though that it's time estimation for the battery discharging is entirely inacurate, resulting in the battery running out before gnome-power-manager shuts down the system.
I am comparing the information provided by upower with that provided by the apcupsd set of programs.
That being said, when the battery is CHARGING, it would appear that upower reports very similar numbers to apcupsd.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Plus UPS in
2. Disconnect power
3. Review discharge values
upower reports massively innacurate times.
upower to report similar numbers to that of the UPS it self.
I have also noticed that the gnome-power-manager appears to be recording no battery statistics for the UPS battery, for discharge/recharge rates or battery charge level.

This has been taken part way through the charge cycle, the more "charged" the battery the greater the disparity.

This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '17'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 17's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 17 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged change the
'version' to a later Fedora version prior to Fedora 17's end of life.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
