    i have a cheapo wireless camera that can run continuously for ~3hrs on 9v
    battery.

    looking for ways to extend the life of a 9v battery used in the camera ?
    that is extend the length of battery replacement time ?

    will on/off cycles, e.g. 5 sec on/5 sec off give an extended say 6 hours
    operation or would on/off cycle be more draining ?

    TIA

    use a larger battery.
    possibly sliggtly more draining. I'd expect atleast 5.5 hours.

    on/off cycles(50%duty cycle) will help extend the battery life by only
    63%

    the battery life will improve more than 63% for duty less than 50%.....

    instead use two 9v bat. in shunt....
