    I tried measuring my charge differently, and got some interesting results.

    In trickle, I am putting in 0.8W
    I arrive at this figure by measuring voltage of the battery, and current in
    or out 10 times a second, and totaling up watt-seconds, then dividing by
    total seconds, which I've run for as long as 2 hours.

    This is roughly 1/30th of the pack's rating.

    Given that the charge efficiency is not too high when fully charged, does it
    seem that I'm in a reasonable zone?

    My trickle charge is implemented by a varying pulse width of 2.5A at a very
    low duty cycle, about once every 10 minutes.

    This is what I get for posting at 4:30 AM.. :)

    I forgot to mention the 0.09A constant load across the battery!
