Battery Questions

I've been in the habit of ordering 3000 mAh 18650s, but at work, a friend wanted to test why his lights weren't working and gave me the somewhat ill-reputed 2600 mAh blue-labeled Trustfires. My C8 seemed a bit brighter with his batteries than mine. Does the lower mAh number give that affect? One of you smarter fellows give me the low-down, please.

Also, I've been going about to order some RCR123s, but on the Olight website, it discourages their use in an Olight M31 Triton due to supposedly not being able to hold up under long use. Care to shed light on that and what I should expect? I have a friend who uses nothing but those with P60 dropins and never has a negative thing to say about them.

The mAh is just the capacity of the battery, 3000 is greater than 2600, these 2 pints of milk is greater than 1 pint. It's the quality of the battery that counts the Ultrafire 3000 mAh are not that good for high drain lights like XM-L led lights as they require about 3Amps. This battery is better for low drain lights 1Amp or less. Also internal resistance has an effect on the Apms the Led receives the Higher the resistance the less Apms the Led will receive.

Get quality Trusifre Flame 18650 from DX  or Manafont

The Olight M31 would be better with 2x 18650(8.4v) batteries, that would be the best option. The maxiumum voltage is 12v, so you cannot use 4x RCR123(16340) as this be 16.8v and blow circuits in your light.

Hmmmm , if you can live without the protection circuit ?

 

  Sanyo 2600  , available at several places for under $6 each [ hell of a deal ]

 Always remember , the easiest thing in the world to do , is to expel hot air from your lungs and through some vocal chords ..
The resulting sound may , or may not be worth listening too ….

That's what I wanted to say too. High drain, real capacity. They worth it.

Here are the cheapest if you buy 3. http://www.intl-outdoor.com/sanyo-18650-2600mah-liion-battery-p-135.html

...keep in mind that the Ultrafire 3000 are not even close to 2000mAh, and with high internal resistance (Ω)...

If you search a little, you can find a few threads regarding real capacity of "ultrafire 3000"

Go with Sanyo or Panasonic (in unprotected or protected/rebranded)

Cool. I've had such good luck with Sanyos. As for Panasonic and Samsung, I hear the former is top-shelf quality. Aren't XTARs knocking on the door of being as good?

But how about RCR123s? Which will be the best buy?
