    just a couple conceptual questions.

    Is it better to use one battery until it's gone

    or

    Is it better to use two batteries little by little simultaneously until they're gone.

    Which method is more efficient ?

    Thanks.

    If they are primary batteries, you may as well use them up. Rechargeable types have different responses to discharge, so that must be decided on a case-by-case basis. You would do well to read up on the information at this site - http://www.batteryuniversity.com/

    Primary batteries can "recover" slightly if allowed to rest, and can deliver more energy overall if they are cycled out with another one as in your 2nd strategy. If by "efficiency", you mean mAh delivered per $ spent on batteries, this might be slightly more efficient.

    But the effect is really small and you can lose your mind trying to keep track of batteries. So if you define "efficiency" as minimum human input per mAh, then just use one up and switch to the new one. Invest your time in shopping for better battery prices instead.
