Battery chemistry needs some recovery time, and more so if you're draining
them at a high rate relative to the maximum. If you test by flashing once
every 5 minutes or so you'll probably get consistent output over more than
10 flashes... but test 10 in a row at 'just recharged' or e.g. 'one per
minute' and you will probably notice this falloff. Let those alkalines
recover for an hour or so, and the output will be back where it was
initially, unless you've drained them significantly from new.
This repeatability of capacity (for lack of a better term) is where the
Quantum battery people make their money... a Bounce Grip 2 would give you
faster consistent recycle times, because the four C cells have -much- more
capacity that four AA cells do. Besides you need a BG-2 just for the handy
handle and the pro look <g>.
