IC. That won't really give you any meaningful results, it's all just a guess as you point out.

I've had very good luck with Tritons over the years, that's why I was curious.

I'd do at least two charging cycles on both Duralite and Triton, discharging on a Triton (or any other charger that tells you the amount of mah drawn from the pack). The discharge numbers should give much better idea what is actually going on.
