Battery life of Moultries?

[pabowhunter22]

How low can the battery life drop before the camera stops taking pictures. I have the I40. (I'm assuming it can't drop all the way to 0%.)

I have never been to mine when it was below 10% that is wasn't already dead. Not saying it won't go all the way down to 0% but I have only seen it as low as 10%!!! The other times it was already dead....
