Thank you very much
It’s on the to- done list 
. I’m charging cells now; I’m hoping to get beamshots tonight.
From what I’ve read other users have measured something like 550 days for the parasitic drain to drop a cell to 50%.
Edit: I’m measuring .08mA parasitic drain. So about 1276 day to dead, or 638 days to 50% on an Eneloop Pro 2450mAh cell.
Heading outside for beamshots.
looks good now 
Fantastic.
Thank for the nice review and absolutely nice pictures
I have this light from 3 month, is a great light, good throw for the size, like a lot the slim factor for a 4xAA power bank.
I have only few complains (the perfect light does not exist yet :laughing: )
- the grip is not so great even with hard anodizing (with the dry hands I “succeed” to drop form ~1 meter on a wood surface, but all ok)
- the led is not 100% perfect centered (but I didn’t see any bad effects)
- the ATR system enter to fast on turbo mode (just a little warm and immediately steps down
)
But like I said, overall is a great light, I love it
Bellow few pics with mine
Great review!!! I’ve had one of these for a while now and it has become one of my favorite, most used lights. Pair it up with some Eneloops and it is just about the perfect package as far as I am concerned.
I think Nitecore hit a ‘Home Run’ with this one.
Re. “Press and hold both switches for more than 1 second to lockout the flashlight. Press and hold both switches for more than 1 second to disengage the lockout.”, does that mean that there is no parasitic drain when it is locked out, since this is not a “mechanical” lockout?
Hi,
I noticed that Kaidomain still lists the SD10 as “in-stock”:
http://www.kaidomain.com/p/S022428.Lumintop-SD10-Cree-XM-L2-T6-4-Mode-800-Lumens-Flashlight
Does anyone know if they actually still have these in stock and ready to ship?
I thought that the SD10 had been discontinued?
There is parasitic drain; the light is continuously monitoring to be unlocked while it is in lock mode.
Funny y’all should bring up “parasitic drain during lockout” concerning this light. I got curious about that too after reading about that little Nitecore key chain light thing.
I just started testing one of my EA45S’s back on 19 September 2016.
Here are the results so far.
- Light Nitecore / EA45S
- Batteries / Eneloop ‘PRO XX’ AA _ (HR-3UWX min 2400mAh / 11-05-EE) _ Batteries fully charged, rested over 24 hrs. then installed.
Date…9-19-2016……10-3-2016
Time…08:00…………16:10
- … 1.387v…………1.326v
- … 1.388v…………1.328v
- … 1.391v…………1.326v
- … 1.391v…………1.327v
My Eneloops are flat, light doesn’t turn on after a few days without using AT ALL! I have tried many sets of fully charged batteries, all dead within few days.
Is my light faulty?
Hmmm, how many days is “a few”? Something doesn’t sound exactly right with it for sure.
The post above yours is what mine measure after two weeks. I am gonna update that post every two weeks or so and see what happens.
Even for Nitecore parasitic drain, that sounds excessive. One tip to pass on: On many Nitecore lights, Once you put the cells in, turn it on for a second or two before putting it in lockout. Seems to cut down the drain considerably.
That certainly sounds bad. I’ve heard of high parasitic drain with other models, but not the EA45S.
I rechecked mine with my new UT139C DMM, I’m seeing 96 microamps which is a little over a 1000 days to dead cells.
Yep. The same amount of parasitic drain as when the light is not locked out. The lockout just prevents the light from turning on accidentally.
that would be logical, but not sure it holds true in all implementations

What do these results indicate so far?
Just the parasitic drain with the light on “Lock Out” and zero light use.
What I was asking is do the numbers tell you anything yet? The drain can’t be too bad, right?
