Life of LiPo 3.7v 500 mAh battery

Life of LiPo 3.7v 500 mAh battery

(OP)
I am working on a project and we are using a LiPo 3.7v 500 mAh battery and I want to know how long the battery will last. We are using bluetooth and the circuit is only on for about a millisecond before it goes into sleep mode. The chip transmits at 60 mA and then goes to about 1 micro amp in sleep mode. How can I calculate how long the battery will last? When I try to calculate the time I get an absurd amount of time, like 20 years. How long do LiPo battery's last when sitting Idle?

Here is a link to the battery that I am using.

RE: Life of LiPo 3.7v 500 mAh battery

You've not said what your duty cycle is, so the answer could be anywhere from 11 months to 57 yrs. But, the high end is limited by self-discharge, so no more than about 3 yrs.

How long do you want it to last?
Is this to be a product or just a project?
