The only lasers I own that are portable use AAA batteries. Not 10440's either, just 1.5V alkalines. :shhh:

Figure out a way to put a set, measurable load on them then time them untill they die.

4000mAh = 1 amp for 4 hours, 4 amps for 1 hour, 500mA for 8 etc...

the big thing for me when it comes to batteries
made in china and japan is they can put whatever they want on the battery
i had a few of the 3300mAh ultrafire and they lasted about half as
long as my AW 2900mAh batteries ,,guess you get what you pay for
and all the 18650's were charged on the same charger :thinking:

i found these batteries a while ago.... ultrafire never made those...

so in other words they are knock offs. I wouldn't buy them. too risky.

I use a lot of #18650 cells.

The very best right now are 3100 mah Panasonics . . .

and they are rare.
