do you have a multi-meter? measure how much current is moving through the
battery...

that's a big range... what determines the actual current?

================

a slightly larger rechargeable battery (1/3 AA) would have a better
amp-hour rating, and would last longer than a 2032. i've seen gear with
original 10-15 year old lithium batteries running strong.
