The i3Es put out a good amount of light with AAA alkaline batteries. But some day I might buy NiMH batteries for the first time in my life. LiFePos seem like the best compromise between output and and runtime, but I worry about the heat using anything higher than 1.5 volt in them. I have a bunch of 10440 batteries, but if the flashlight gets too hot to hold, I'm not even going to to put them in these. For me, key ring flashlights are backups for when my other light die, or what I use to find them in the dark, or unlock doors to turn on the lights. 35 minutes with an alkaline battery is a decent amount of time when you only use it for a half minute here or a minute there. Good, informative video.
I’m just getting into flashlights and so far it’s all the battery types that are the biggest learning curve. These videos are super helpful, so thanks!
Thanks PME for during this battery runtime test on the Olight i3E EOS. I try to take out the alkaleak as soon as I receive the flashlight. I generally use a hybrid NiMH battery [eneloop or Ikea Ladda] in mine. I just took last year's green snowflake out of my Dopp kit and hung it on or Christmas tree along with this years red snowflake version. For a flashlight I rarely use, I really like these little lights, especially the revised ones which now have double o-rings, presumably to prevent head loss, and it can't hurt the water resistance either. At about 0.3 ounces or 8g for the empty flashlight, they make an excellent little backup, which takes a commonly available battery. With the NiMH they weigh in at about 19g which is probably as close as my scale can come to the 18.4g spec with the included alkaleak. It is good to know how long I can expect to have light. I have compared the i3E to a similar competitor's flashlight which specifies more lumens, but to a daughter and mine eyes they appear to have the same brightness. Further, I can see better with the Olight as its CW is not as cool or blue.
Great review! Love NiMH rechargeable batteries 🔋Also much better for the environment!! It's important to note they are not prone to leak like Alkaline cells are !
@@PardonMyEnglish Did running the NiMH until it died mess with the battery at all? Also, good to see that it dimmed for a good amount of time rather than just shutting off! I love the I3E and I'm an Eneloop junky
I’m glad your like me and play around with different types of batteries in flashlights. I get a lot of people that say they would never do that because they are worried about burning out their flashlight emitters. Great video broski! 🤙🏼
Thank you, sir! Yes, it’s interesting to see the differences and I hope these videos can help people decide what batteries to use. Thanks for the support 👍
Doing well, Marc -and I hope you are too! Yes, I’ve had this test in mind for a while but didn’t have a way to charge those NI-MH batteries until now. Glad to help share the findings and God bless you!
Good question. I actually do not have one but I’m in the market. I think I used to have an old Winchester multi tool from back in the day but I lost it years ago unfortunately.
@@PardonMyEnglish oh ok I never heard of Winchester before! Was that a good tool brand? Back in the day? And what kind of multi tool would you be interested in now ? Is there a certain one that you have had your eyes on?
I owned an Olight li-po AA, it came with some flashligt, S1A Baton i think. I kept it and kept it until 2 years after, selling the flashlight i noticed the battery was almost dead. I sometimes sell or giveaway flashlights to have a reason to buy new ones. Edit: when i bought the flashlight it was already out of production, i waited 1 month to come from some deposit wordwide. So it was probably almost dead since then.
The best battery for you is the battery that's available in your country. We only have Vapcell lithium ion here in Philippines besides ordinary batteries.
Great vid on an awesome topic! First to switch off: expect. However, last to go? Didn't see that. And crazy runtime too! I think it's really a 1000mAh battery. I have a 700mAh Energizer. Will test on my i3E.
Alkaline batteries start at 1.5V and drop to ~1.2V pretty quickly under load, which explains why it was hard to see a difference in output with alkaline relative to the NiMH battery NiMH batteries are slow to charge, can't really get around that. Chargers use low amps. Getting hot ruins the batteries and the goal is to reuse them
Good points here, thanks. Yeah, I had the NI-MH batteries for a while without a way to charge them. I finally got a charger and was surprised that they took longer to charge. On the bright side, they also take a long time to discharge and that capacity is impressive 👍
Always love your content. I'm thinking of getting a 18350 3.7v battery. But I'm stuck on "Max continuoes discharge". Some are 3A, 4A, and even 10A. Does it really matter?
Good question. I use the Miboxer C4 charger to charge my batteries, but this is the best value option I could find if you're just looking for a dedicated NiMh charger and AAA batteries: www.amazon.com/HiQuick-Rechargeable-Batteries-Battery-Self-Discharge/dp/B0B9XMJXWP/ref=sr_1_5?crid=2GTHTLHYADCNS&keywords=aaa%2Bnimh%2Bcharger&qid=1704763883&sprefix=aaa%2Bnimh%2Bcharger%2Caps%2C120&sr=8-5&th=1

Glad to help! Flashlights are fun but there is a lot of lingo, etc. I am still learning about LEDs and other components, myself.

I use the Soshine LiFePo 10440 with my Olight i3e and love it. It gives me the extra boost in lumens I want without all that heat.
Yes! It seems to find a nice sweet spot in that regard.
Your review here is just what I needed to know. Great work. Keep it up.

I still need to do more research but I’ll probably go with one of the smaller Leatherman options (like the rebar, sidekick, or wingman).

Ah, I see. Yeah, the good news about some of these lights is the ability to swap batteries. I think that makes their lifespan a lot longer.

Hi! How long does it take to fully charge the 1.2v pkcell?
Good question. With a 60mA current charger, it will take around 15hours. With a 180mA current charger, it takes around 4 hours.
@@PardonMyEnglish Thanks! thought i had a problem with the battery, it just needed more charging time.
Please suggest good NiMh battery with charger

I would follow the manual to be safe but you may be able to call the manufacturer to ask them if Alkaline batteries could work.
