I have a Dell Latitude D830 with 2 batteries; the standard 9-cell battery plus a 2nd media bay battery that goes into the DVD drive slot when the drive is removed.
Both batteries are reported correctly on my desktop background with the Sysinternals BGInfo program:
• Battery Name(s): DELL 00
DELL 00
• Battery Charge(s): 100
105 %
The following tags are being used to report this data:
<Battery Name> WMI Query SELECT Name FROM Win32_Battery
<Battery Charge> WMI Query SELECT EstimatedChargeRemaining FROM Win32_Battery
Specy reports the battery data like this in the Operating System section:
Battery
AC line Online
Battery full time Unknown
Battery Charge % 100 %
Battery State High
Amount of time remaining (sec) Unknown
It should be a simple matter to incorporate the WMI Query into Speccy. Hope this info helps.
