Sorry for the delay guys...the batteries are at my shop, and I'm out of town now...no results until next week. Oh, and sickrick, I can understand your trepidition re: absolute shut-down time, but I'm really just looking for a ballpark. When I tape, I'm not really in the habit of running my battery power down to the last ounce of juice. It'd be nice to know that for a fraction of the price, one is able to get roughly the same runtime as two internal batteries.
Caveat, folks--all tests will be conducted with an Amstel Light firmly in hand.
Talk to you in a few.
