    I recommend a battery meter that shows amp hours removed/replaced from the
    battery bank. Running the Diesel every several days might not do it, the
    only way to tell is with the meter, or careful calculations from a digital
    volt meter. There are so many variables: battery size & condition,
    connection quality, alternator size, type of regulator (The internals don't
    give full charge for very long), then the amperage and hours run of each
    piece of gear. Without the meter, you just don't have much info to go on.

    I have lived on house batteries since 1997, and I have an amp hour meter.

    I have learned that my AH meter, an E-Meter, is only an convenient
    approximation and has sometimes has been wildly inaccurate. The best indication of
    state of charge is testing the specific gravity with a hydrometer.
