mod-zigbee-pir battery questions

[sophana]

Hi

I have a few question about the mod-zigbee-pir module.

Is there an estimation on the battery life when using the demo software (sleeping while waiting event)?

It is written 3 to 3,6v. Does this means that it is not compatible with nimh batteries?
So I must use non rechargeable batteries? Are there rechargeable battery solution for this?

Can it read it's own battery voltage?
I suppose I can set a timer to wake up the module every minute to read and send the température? Do you think the battery will last much less?
Is it possible to configure button pressed and button released waking events?

Thanks
