I had a long discussion with Ian yesterday on how
the system determines battery status. I will try to summarize how the
system works.
The first issue that one must understand is that
it is not possible to determine the battery life when a battery is being
charged. Only by putting a battery under a load can the life of a battery be
determined. Therefore to determine the battery life the AVTS unit does
the following:
1) When the AVTS unit is first turned on, and a
battery is present, the system operates for the first 130 seconds on battery
power and determines the actually battery life. During this time the system
reports the battery status of the system when it was last turned off.
After the initial battery test is completed the revised battery life is
reported.
2) After the first 130 seconds the AC power is
applied to the system and the battery is in a 'charging' state. While
the battery is in a charging state the system watches the battery voltage and
current flow to try to 'estimate' the battery life. Only when the
AC power is lost or the system is turned on again is an actual battery life
determined. The actual battery life verse 'estimated' life is dependant on the
type and condition of the actual battery.
It appears from the reports we are getting that
the 'estimated' life is too great which is why you are seeing the battery life
suddenly drop from 99% to 87% after the 130 seconds.

to followup - turned it on this morning and
it said 99 - now - 10 minutes later it says 82%

Yes, I also see that. The unit will be at 99% and
when I just turn it off for a few seconds and then back on,
the battery goes down to 87%. Have you ever seen it at
100%?
Ravina
has anyone noticed that if they are
using the R6 and it says 99% charged and then turn it off and on the
next day that it says charging at a lower % say 85% -like it lost
14%
this is what I am seeing and need to
verify with someone else
Thanks
