Scott: Tough question........ how long is long? Depends on how much time you use it each day, as with anything else. It uses very little battery while just sitting there. Are you a constant volume tweaker? That emits a continuous stream from the IR. Lotsa macro use? That'll use up some battery. But, the Palm lllx is very good on batteries. I use mine regularly each day and get 6 to 8 weeks of battery use (cheap batteries). But that includes about 3 megs of appplications and docs to keep in memory including many alarms, etc.

My Palm Pilot for URC use lasts about 3 months using the OmniRemote software without an IR extender. The IR extender will use the batteries up a little faster.

Hope this helps.

And yes, a Palm V is way overkill for using just as a URC. If you have the lll, use it. If you don't and want a PalmOS device as a URC, get a Handspring Visor with the OmniRemote springboard module.

But, as always, that's.....
