Looks OK.
Energy. Battery has N joules (power * time). Look at powers.
Also, in real life, depending on battery chemistry, it may be inaccurate. How inaccurate depends on pulse rate, battery chemistry, internal resistance, ... If you're never discharging the battery faster than 1C, it's probably OK.
Hi All,
I would like to estimate the battery life of my Rx receiver which has an ON/OFF (wakeup / Stdby) duty cycle.
Current Av = [(Iwake * Twake) + (Istdby *Tstdby) ] / [Twake * Tstdby]
Where Iwake is ON or wakeup current (mA) Twake is wake up period (s) Istdby is OFF or standby current (mA) Tstdby is standby period (s)
When I know the average current I can work out the average battery life
Hours = mAh / Current Av
OK so far?
Any other ways of looking at these calc's would be appreciate

Thanks Ian.
I'll do some calc's with power and time.
Regards Joseph
