Difference between the 2016 and 2032 button batteries?

    I have a set of 3V CR2032 and 3V CR2016 batteries. I notice the 2016
    are thinner, but they have the same voltage. As a newbie, what is the
    major difference between the two?

    Thickness (3.2 mm versus 1.6 mm) and energy capacity (225
    milliampere hour versus 90 milliampere hour).

    On the shelf, maybe, maybe not. With a given current drain
    rate, yes. For instance if their load drains 10 micro
    amperes, the 2032 will last about 2 and a half years, while
    the 2016 will last about a year.

    The thickness; 3.2mm VS 1.6mm.

    Not necessarily.
    Dependent on thermal history.
    Hallmark once used to make greeting cards that played music when
    opened; used a dinky ASIC, a piezoelectric sounder, and a lithium battery.
    Most of them arrived at stores DOA because Hallmark, in their
    stupidity treated these greeting cards exactly like all other greeting
    cards: they went into hot warehouses for later distribution.

    They have different energy capacities, just like the difference
    between AA, AAA, C and D cells (which are all 1.5V nominal).
    The CR2032 will be able to deliver a given amount of power for a
    longer period of time than the CR2032.

    It's like the petrol tank in a car. The engine will use the same
    amount of petrol (power into a load) regardless of the size of the
    tank, but a bigger tank (greater energy capacity) will get you further
    than a smaller tank.

    actually,lithium cells have a long shelf life,and a wide temp range.

    The type number of lithium coin cells indicates their size
    The first 2 digits are diameter in mm, the second 2 the thickness in units of 0.1mm.
    Capacity is rougly proportional to volume.

    They probably used a super-cheap alkaline battery (I'd guess maybe 1
    cent each) rather than spend an order of magnitude more for a Li cell.

    Wal*Mart still sells these today; you can get perhaps a dozen different
    melodies depending on the card you choose. (I don't think they're Hallmark
    brand, though.)

    Perhaps; the shape and size was "suggestive"...

    If they have been sold for a goodly number of monthe, then the maker
    and/or the disty most likely learned the "Hallmark lesson" and treat
    them like batteries and not cards.

    a LED flasher I've gotten in an OTC supplement used the CR2032,3 of them in
    parallel.

    My PC uses a CR2032 for it's CMOS battery.

    Cards of 5 for a buck are at some of the 'dollar stores' at local
    flea markets. 25 for $5 and I haven't found a dud yet. I bought these
    at "The Markets Of Marion" last year, and I see the vendor with them
    every few months, when I go back.

    Fedex ground should handle them-- it's a prohibition on shipping in
    aircraft-- maybe only passenger aircraft.

    One of our products uses a CR2354 as ram backup for an MC68332
    processor, to save cal tables and such. We've shipped over 3000 units,
    for about 10 years. We pulled the batteries from various RMA units and
    discharged/datalogged them to determine remaining mah capacity. There
    was no correlation between age and remaining charge. In fact, the best
    few batteries were among the oldest.
