Fenix E35: Difference between 18650 2600mAh and 18650 3000 mAh?

Just curious what you guys are using in your Fenix E35 as far as teh 18650 battery. Will a 3000 mAh Lith Ion battery work? I've seen a few people suggest the 2600mAh but wasn't sure if that difference would matter?

I use eagletac 3100 or non-branded panasonic 3100 cell.

So I'm guessing its not gonna make a difference between a 2600 mAh and 3100 mAh? Either would be fine? Trying to figure out whats the best bang for the buck battery to use in this torch.

The 'mah' reflects capacity, so if a 2600mah battery would run in a light for 26 minutes then a 3100mah one should run in one for 31 minutes before running out. Of course there are other key considerations too, such as whether the claimed capacity is accurate, and that some batteries hold voltage better and so provide the same wattage at a lower current which extends the time between charges above what their relative capacity would suggest.

Also, quality, safety and size are all important considerations which aren't directly reflected by a cell's capacity.

Redilast 3100 protected and Samsung 2600 mAh cells are rotated through my E35 with no difference in performance other than run time. You could probably also use the new 3400 cells, but I haven't tried them.
