"Incidentally, EagleTac rates the T100C2 at 2 hours Hi mode on the packaging. Assuming this rating was with EagleTac batteries as well, it's been underrated quite a bit as the tests show it getting just shy of 3 hours"

The box specs are for the CR123; the light is spec'd for 3 hours on the Eagletac 18650 at PTS in the description Eagletac is spot on with the lights capabilities with their battery.

Cool thanks for the headsup, I'll edit that redundant bit out

Updated with Pila and Wolf Eyes cells.

Seems my mini 18650 shootout months ago was dead on

Thanks for the shootout - it's been needed for a while. I wonder, how would Trustfires perform? (I believe they are different than Ultrafires)

[Mev]

Are you refering to these TrustFire's?

If so, I could purchase them to test out.

I'd like to see those too. According to 'Lermite' tests they have really decent capacity.

From my experience Trustfire 2400/2500, Solarforce 2400, EagleTac 2400 and even some Ultrafire 2400 have decent capacity. And all perform quite similar. But up to 10% difference between two pieces of the same brand is not uncommon. Also loss of 10-30% capacity after 6-12 months of usage is unfortunately quite common.

Hope that coming AW 18650 2600mAh will perform better than current 2200mAh

Alright, I've just purchased those TrustFires.
Will update the graph when I get them.
