Olight i3T vs. 3.7v 10440 Lithium Rechargeable Cells - A Runtime and TURBO Endurance Test
Like many of you, I’ve been curious how the Olight i3t can handle constant usage of 3.7v 10440 lithium rechargeable cells. Will the LED survive? Will the light overheat? What kind of runtime do these batteries offer? In this video we try to get some answers to these questions.
Note: Olight does not recommend using any batteries other than those indicated in the product manual. The 10440s used in this video are from PK Cell and have a capacity of 350mAh.

Super happy you made this video! I have been looking for someone to test this exact thing! I kinda didn’t want to ruin my light. Thanks for taking one for the team.

I run these same exact batteries in my I3t everyday and it still works just like it did when it was new. It's a great little light.

I want to thank you for showing this awesome setup! I’ve been looking for this exact thing for over a year now. Compact, light package that packs a punch with reliability and simplicity. I feel like I’ve tried almost every small flashlight and haven’t come across a light that beats this setup yet.

I can’t take credit for discovering it but I’m glad the videos can help. This is still my favorite as well 👍
Great video, thank you
I bought an i3t for a life long friend precisely because of the possible huge light output achieved if someone should decide at there own risk to use a wildly overpowered battery in it. Thanks for destruction testing yours.

I don’t have experience with that one but people seem to like it from what I hear.
I bought the i3t as a bundle with a 20cv benchmade bugout. I really just wanted the knife but got the light with it just for shits and giggles. Didn’t know anything about it. What a stroke of luck this has been to get what is really the most versatile little edc light on the market.

Nice! Yes, it’s still the best in the AAA size category in my opinion. Tough and reliable for sure. Mine is still going strong even after the abuse I’ve put it through.
Have been a Streamlite MicroStream AAA flashlight user for years. This thing better be as bulletproof as that flashlight's all I gotta say.

So you were able to pickup the light after 20 minutes? And it didn't melt the circuitry....should mean it would be easy to hold at "step-down"...you should do a "held in hand test ...to step down...while at max lumens" :)

@PardonMyEnglish
Жыл бұрын
I found them on Amazon. The only two brands of 10440s I’ve tested are PK Cell and Demon Fire. The Demon Fire cells are nice because they are protected but they are slightly longer so they are a tight fit in the light. The Demon Fire cells also didn’t come with a recharger.
What about the i3t plus ? And i3eos can thay also take 10440
@PardonMyEnglish
Жыл бұрын
Good question. Unfortunately 10440s won’t work in the i3T Plus. Because the batteries are stacked, the voltage doubles to 7.4 and the LED can’t handle it.

I don’t think mixing the batteries will work unfortunately. Also I don’t have an i3T Plus so someone else will have to try this if they’d like. 10440s do work in some i3Es but not others for some reason. I actually have a couple videos about this if you’re interested: The Olight i3E + 10440 Mystery - A Possible Solution kzread.info/dash/bejne/dWthyauwfZbPiNo.html
Have you tried these batteries in an i3t plus?
@PardonMyEnglish
Жыл бұрын
I have not tried that but I don’t think it would work because the batteries would be stacked and connected in series. This would double the voltage to 7.4v. I doubt the light would be able to handle it.

I slowed down the playback speed to .25x yet i cant read the card at 60 minutes. Your handwriting is hard to read plus the speed of the video. I think you used 3 batteries to reach 1 hour using the HIGH LIGHT OUTPUT SETTING. Hopefully i understood your video correctly.
