haha I had some arrive with a cheap torch that claimed 5,000! they didn't test more than 800. I do have some 26650s that test over 5,000 BUT they are a hell of a lot bigger than 18650s.

Total BS. A serious case of Chinese exaggeration. There are very few manufacturers can can make a true 3500mAh cell at the moment, let alone a 4800mAh 18650. That's the realm of the larger 32650 cells.

Cheers Quentin; I suspected as such

If it's too good to be true, it probably is

As a rule you'll be lucky to get 25% of the stated capacity with that sort of cell.

When are these dam headlights going to be in stock?

Ah. Now the seller has black listed me because I've asked if he's tested the mHa! Dork.

Post a link. Sounds like they need to be flushed out as BSers

Hi fellas I'm keen on another 2 sets of batteries, just point and shoot on Trademe or any better suggestions??
7 possums last nite got about 2 - 2.5 hrs out of the ones that came with it.

Try Maxtoch on aliexpress or @burtonator.

@gadgetman, is there a simple way to calculate mAh in of a battery or is it simply a case of working out consumption and timing how long the device runs for before the battery is flat?

Basically you have to measure current vs time from full.

Thanks @gadgetman - hoping for a simpler solution!

@mkm, it can't get any easier, Maxtoch are one of the top 18650 batteries around, Burtonator is a member of this forum, based in Nelson who imports direct from Maxtoch. Or you can also order the batteries yourself from Aliexpress. It is as easy as easy is.

Cheers @ROKTOY - got a couple of Maxtoch off @burtonator earlier this year for a Armytek headtorch (great piece of kit so far). Picked up a couple of cheap Panasonic knockoffs from Aliexpress for a C8.

Was curious to know the actual capacity of the Aliexpress ones!
