    Default amp hours

    Hello everyone. I have a question that is confusing to me. If I draw 1 amp from a battery for 1 second and do this 2 times per minute, how many amp hours am I draining it? I'm trying to figure out the battery life. Thank you.

    It simple...
    1 pulse drain 1As(amp second), or 1/3600 Ah.
    You have 2 pulse per minute, and 60 minutes in hour.
    So you get 2*60*1/3600 Ah.
    Or if you want to calculate how big battery need to be for a day, just multiply that with 24, or what ever period you want.
