Oh damn you have to buy quicker lol I just seen a post a couple days on a16340 with 1300mah … I want to find a way to buy them … that will defiantly help the run time on my on the road m3 and this light if I decide to use that configuration … Test/review of Aspire INR18350 1300mAh (Black-yellow)

FWIW, more mAh does not necessarily mean more runtime on turbo, in high-powered lights like this. Batteries tend to come in either high-mAh or high-current varieties, and the high-current ones tend to perform better (and longer) on high modes even though their mAh rating is lower.
However, the high-mAh batteries (if they’re legit) should have more runtime at lower modes.
Effective capacity changes with the amount of current being pulled. This effect is smaller on the high-current cells though, and can give a high-current cell more effective capacity (relatively) if the current is high enough.
If a battery’s specs are unusually high, there is a good chance it’s fake. Normally if I saw “16340 with 1300mAh” I would expect it to be fake, since those don’t really exist yet. HKJ’s measurements suggest that one is only exaggerating a little though, making it the first 18350 with ~1200 mAh.
That’s interesting, I’m somewhat new to detailed info on lights …I just thought mah would mean the more power it can store, so no matter if running turbo or low mode it would run longer then a battery with lower mah… I need to look into this it’s interesting thanks for the info … but sorry for getting off topic of the s42…
It depends, and the only way to get good numbers is to measure… but, fortunately, HKJ measured.
On that particular cell, it looks like ~1170 mAh on low modes, ~1100 mAh on medium modes, and about ~1000 mAh on high/turbo. Which really isn’t bad at all.
On 18650 lights, it’s common for a 3000 mAh high-amp cell to last longer than a 3500 mAh high-capacity cell on turbo. The cells optimized for capacity tend to have much more voltage sag under load, and also much more capacity reduction under load, which makes them dimmer with output dropping faster… while the high-amp ones stay closer to their rated voltage and capacity.
Sometimes voltage sag can be a good thing though, like when direct-driving a Nichia 219c from an 18650 cell. A high-amp cell can fry the emitter, while an older saggier cell is safe to use. But this is kind of an unusual case.
Got to be quick. They sell almost instantly when they come back in stock. I got the XPG3 last night cause Nichia sold out before I could get it. XPG2 is still available but doubt anyone wants that.
Shouldn’t those who have pre ordered the Nichia variant be dealt with first? It seems that it is whoever is quickest to the button that succeeds in getting one? That sort of defeats the point of pre-ordering.
