Oops - I meant 225mAH , sorry about that. Regarding the 10 minutes of ON time. We haven't nailed the times down - 10 minutes is an estimate.

If nothing has been detected after that we'll shut down. --- In AVR-Chat@yahoogroups.com, "David VanHorn" <microbrix@...> wrote: > > On 11/29/06, Richard Cooke <rcooke@...> wrote: > > > > Hi Folks, > > > > I'm working on a battery powered consumer product that will use a 3V > > button cell.
