What is the mAh rating on the battery that comes with this flash light? Can it use 4000mAh batteries for better performance?

Sorry, I dont know the answer to that question. I really like the flashlight. It has all the power and brightness I could want.

First, no one makes 4000 ma 18650 batteries. Panasonic makes 3400 ma batteries and they had to remove the protection circuits to do it. So lets be generous and say your getting 3000 ma from the batteries, the most the xml t6 will put out is 930ish lumens if its direct driven and doesnt catch fire from being inadequately heat sinked. keep this in mind when looking at all the lights of this type. 500 lumens would be more likely.

This flashlight uses only one AA battery which puts out 1.5 volts. 18650 batteries put out over double that so the bulb may not last very long. With one AA battery in this light it is extremely bright so I would stick with just the AA.

It uses 4 BRC 18650 3000mAh 3.7V li-ion batteries which I bought at the same time as the flash light

Yes the 18v 1.5Ah battery works on this flash light. I had it to on over 5 hours without turning it off.

With my MB-D200 I carry the charged EN-EL3e as a spare and 6, 12 or more rechargeables (depending the assignment) These are 2500 - 2900 mA NiMH and generally last more or less as long as the proprietary battery. I have not seen much performance difference between expensive and cheap ones, but I guess the cheap ones will just die sooner (well, maybe not...) In the case of the MB-D10 of course, you would have to pack multiples of 8. Anyway, I always carry a box full of charged NiMH's, because I have to "feed" the flashes as well.

I use only rechargeables. See if you can find a brand that is rated at least 750 mAh. I did have a backlight issue (see my review). Sandisk responded that the backlight will not respond if the battery is low, even though the player will still play. All the more reason to use rechargeables, since if you really need the backlight, you'll be throwing away good batteries before they're completely used up.

Not familiar with the 16340. I'm using CR123A 1400mAh from BatteryJunction.com at a buck apiece ordering the 12 pack, with great performance and long life with frequent use. I was given some CR123A 1200mAh rechargeables and am not happy with them. Lower performance and much shorter life. The BC10 is a excellent pocket light.

I'm sorry, but I can't answer that question, since I never timed it. I can say that this is a super bright flashlight, with a beam of great range and width. I mainly use it to keep tabs on what my dog is doing in my back yard, and it lights up a great swath of the yard. I have been more than satisfied with the duration, and recharge the batteries about once a week, but I cannot quantify the battery light in terms of "How long does it last @ 4000Lm?". I have three sets of batteries, so I can pop a fresh set into the flashlight if its brightness begins to wane. I can say that it does not seem to have a sharp cutoff - the brightness just begins to slowly diminish.

The 18650 battery will work. Its designed to use 18650. However, not sure if quality 18650 batteries come in 4000mah.

I have the 4000 mAh version which is not pictured on the page I'm looking at right now. But according to the back of it, it's Output is 5V ~ 0.5A.

The light takes the 18650 3000mAh 3.7V Rechargeable Li-Ion Battery. You have to buy that separately. Try an UltraFire, they work fine. BUT...as for the light, see my review on this scope combo. The light is the worst part of it - you'll want to buy a better light. Still worth the cost overall.

The description on my order says 4000, however I see nothing on the battery pack that indicates this. I am very happy with this light and would highly recommend it. Very bright and powerful for night use.

I checked the batteries and the branded box they came in. There is no mah rating; only the voltage. Perhaps Duracell doesn't want you to know.

Don't know the mAh on these batteries but I use them in my hat light and they last for days using them 4hrs a day minimum. It now cost me under $.50 to change batteries vs the $10 for name brand. When you swap out 4 batteries in your hat and it cost almost as much as the hat it doesn't take long to figure this one out. The big name batteries last the same amount of time as these for 20 times the cost. I'll take the $.50 option thanks.

My Trustfire High-power Super Bright 8500lumen 7x Cree Xm-l T6 LED Flashlights all function as advertised but ONLY when the batteries are 26650 batteries rated as 5,000 mAh. The 18650 batteries are not robust enough to power the flashlights in all 5 modes.If you still have the flashlight, be sure you have freshly-charged batteries, and invest in some 26650 batteries - Trustfire-26650-5000mah-Lithium-Rechargeables have not failed in use.

are you using eTTL? if your flash is set to manual mode and full power, "+3" then it will use batteries very fast. if the 4AA batteries that power the flash are rechargeable, then you need to charge them right up until you put them into your flash, otherwise they will not have full power. and yes, you will need batteries within the 2400-2700 mAh range, otherwise batteries do not have enough power. also consider a power supply for faster recycle times. also note that lithium-ion batteries get too hot when in constant use and can damage the flash.
