    Hi, Folks

    So, replacing the 78xx series regulator by a LT 1083 ( 7.5 A )could be an idea ... instead of adding cells.


    but ... I must raise AA cells (even the best : 2800 mah ) DO NOT reach the requested capacity ...

    reminds me someone's projects ... but who's ???

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!

    I am using the attached adapter. It should empower a circuitry with 4A for one hour (4Ah).

    As a reference I have a 9V block battery, rechargeable, 200 mAh.
    How are you figuring that?

    Batteries in series, yes the volts are added. Amps are not. The amp output will be that of the weakest battery in the pack. If your batteries are 200mAh, then you can run a circuit drawing 200mA for one hour.
