I realize this is an old post.
We have several TrippLite UPSs and are using these pollers. (Thanks grantsewell !) I've also found and added the following poller but it doesn't seem to be supported (OID not supported) by all TrippLites which has me stumped. I'm not sure if it is firmware version related or not. I'm curious if anyone else is using this OID successfully? If not, how you are determining UPS on/off battery status? I've searched through the TrippLite private MIB 1.3.6.1.4.1.850 and haven't been able to find an OID that supports on/off battery status either. Any advice will be greatly appreciated.

If the unit is on battery power , the elapsed time
since the UPS last switched to battery power , or the
time since the network management subsystem was last
restarted , whichever is less. Zero shall be returned
if the unit is not on battery power.
