Labeled as 700mAh and that's what it does. Interestingly the Vapcell offers a few more mAh, so much for my theory of them coming from the same factory.

I wouldn't trust what is written on the side of the battery for capacity any more than I trust lumen output on lights made 5 years ago... and some still today. If you look at their own testing, they took them down to 2.5 volts when measuring capacity.

According to the tests on the site previously mentioned,
Vapcell INR16340 800mAh (White): 746mAh @1A
HDS Systems INR16340 700mAh (Red): 690mAh @1A

That's the max current HDS lights draw, right?

The difference grows slightly as the Amps decrease.

Is there any reason to grab one over the other?

At 1 amp the differnce in capacity would mean a difference in runtime of about 3 minutes. At 350 ma the gain is about 10 minutes.
The Vapcell did have a better performance at higher currents, though, but for the HDS it's not a big deal.
I bought the Vapcel just because I can get them over here.

Not that I can think of. I don't know what the duty cycles of them are. Too knew to tell. I know Henry was getting increased capacity the more he uses his according to his testing, but that will eventually start dropping like all cells do. The company that manufactured ours claims they will still have over 80% after 400 cycles... whether that is true or not, I do not know.

I would say if you are already placing an order, it just makes it easy to add them. We aren't in the battery business and only did these because when we started doing it, there were no other INR 16340 batteries out there and we wanted to offer some for our customers. I don't trust battery companies anymore than a politician...

What is the continuous Amp (current) draw of a HDS 325 XP-G3 Neutral Long Throw flashlight on maximum lumens?

Reason I ask is that I recently disabled burst mode on my HDS light mentioned above and have been running the light on Maximum for 10-15 minutes at a time. Been using a Fenix 700mAh protected 16340 and an Efest 700mAh unprotected 16340. With both batteries, the light ran great for 15 minutes on Maximum. Then it started to step down and step up and step down in lumen levels sometimes two levels at a time. That step down/up behavior did not happen with burst enabled. Researched the specifications on these batteries and as expected the information was not available for the Fenix and wildly unbelievable for the eFest - 9A maximum continuous discharge and 6A continuous discharge rate. I read that the HDS INR has a 2.1A maximum discharge rate. I am going to do some more testing in the next few days. I will use a primary CR123 battery and then use a HDS Sanyo NCR 18650 battery to see if either of those show the same lumen level "dance" after 15 minutes on maximum lumen level with Burst mode disabled.

My best guess at this time is that the smaller 16340 Fenix and Efest batteries cannot handle the drain of the HDS 325 XP-G3 NLT light on maximum for more than 15 minutes without stepping down. This is interesting stuff. May have to purchase the HDS INR batteries to use my HDS lights the way I want.

Don't forget about thermal throttling. From the FAQ:

Will my flashlight get hot?

Your flashlight protects itself from becoming too hot to safely handle. Even though we do not overdrive the LED, there is still enough heat generated on the highest settings to raise the temperature of the light to potentially dangerous levels. Thus, your flashlight keeps track of the temperature of both the LED and the exterior of the flashlight and reduces power when necessary to prevent your flashlight for getting too hot.

If you have disabled Burst mode, level 24 will run for roughly 4 minutes without a thermal path before power is automatically reduced to keep the LED and your flashlight in the safe temperature range. If you provide a thermal path, such as holding the flashlight loosely in your hand, your body can draw away sufficient heat to prevent the your flashlight from automatically reducing power. Note that Burst mode automatically reduces power long before the thermal power reduction would automatically take place.

Level 23 will often run continuously without needing to reduce power even without a good thermal path - for instance, while sitting on the table. However, should it be necessary, your flashlight will automatically reduce power.

Level 22 and below do not generate enough heat to require power reductions under normal conditions.

Wow. I forgot that. Thank you. And, yes I now feel stupid.

Burst mode will be enabled going forward.

It's easy to forget. I felt an HDS get hot only for the first time this past week after disabling burst playing around with a Surefire slide-on filter.

I wouldn't say HDS get "hot" but definitely can get "warm" before throttling down.
I've played with a few lights recently that are "popular" and noticed one could burn their house down with them... including pockets, automobiles, the break room at work... Get hot enough after 20 seconds you can burn yourself. While many think this is... dare I say... cool, I don't trust them enough to leave them alone without taking the battery out. HDS just designs things differently.

All the HDS run the same amp draw on high.

Don't forget that you also have the 325 Lumen emitter, the highest lumen count in an HDS. I know that my aluminum 200 lumen lights only get slightly warm on level 24 with burst, my titanium 200 lumen on the other hand starts getting hot, or rather toasty (level 24, with the button pushed down the entire time so no burst)

Of course, even with the titanium getting quite hot, you can still bear holding it steady in the hand, and it would not be enough to burn something. I did not notice any stepdowns.

Good to know. Have a test set-up to test my current IMR Efest 700mAh batteries in three lights simultaneously - the Nichia 219b 4000K, the Nichia 219c 5700K, and the NLT 325 lumen light. Temp in the room is 72 degrees F with a fan on high pointed at the heads of all three lights.

From what I have read the IMR's are good at passing lots of current without getting hot while the HDS INR pass less current but last longer. If these Efest IMR's last less than 70% as long (53 minutes) compared to the HDS INR's at 1:15 minutes on level 23 I may be switching. My definition of lasting is time it takes to step down one level to level 22. I may have to perform this test multiple times as I am working and might miss the step down.

Results:

With the 700mAH Efest IMR batteries in the HDS flashlight at level 23 with burst enabled - so I started at level 24(Max), it took the following time for each light to drop down to level 22 with the following voltages, respectively:

Nichia 219b 4000K: 1:00 (60 minutes) at voltage 3.35V

XP-G3 5000K: 1:07 (67 minutes) at voltage 3.33V

Nichia 219c 5700K: 1:25 ( 85 minutes) at voltage 3.40V

My take away is that these 700mAH Efest IMR batteries last a respectable amount of time in the HDS lights at Level 23. The HDS 700mAh INR batteries will probably be more consistent in their run times and last longer on average.

To obtain a tighter sample of average run times would require more testing. This single test was enough for me to answer my basic question on run times of the Efest 700mAh IMR batteries in a HDS light.

Edit Add:

Did some additional testing on the Efest 700mAh IMR batteries by testing three different batteries (#7, #1, and #3) in each of the three HDS lights. I found that the run times are fairly consistent and all more than one hour. Additionally, I found that my Nichia 219c 5700K is more efficient than the other two emitters tested. See below:

I decided to purchase four HDS INR 16340 batteries for three reasons. First, they will likely have slightly longer run times. Second, Henry and Dan picked them so I trust the batteries more than the Efests. And, third, during the Spring and Summer months I go through a fully charged 16340 each and every day so they will get lots of use. I move to the HDS 18650 Sanyo batteries during the late Fall and Winter when the days are shorter and I found I was going through two 16340 battery changes daily.

I wish I could get a few of those INR batteries, but the shipping to Europe is too expensive. I dig your test results RCS1300

Most of the 219c 5700k were over-achievers... very efficient emitter so run time should be longer on that one.
Every emitter varies in efficiency within the bin code, but the High Noon was/is a great performer.

So after the test I did of the Efest 700mAh batteries in post #53, I realized I did not have any HDS INR batteries so...I ordered four of them. Now I have broadened the acronym alphabet of my 16340's. I have the ICR protected, the IMR, and now the INR.

Based on the HDS battery runtime table, I should get a slightly longer runtime with the INR batteries compared to the Efest 700mAh batteries.
