My bad ‘arow55’……….
Looks like in six weeks of being on “Lock Out” with absolutely zero use, the average loss per battery is 0.08525v.
That seems like a pretty minuscual loss to me.
We will see what happens with more time though…. but I am thinking it will be nothing drastic.
Light Nitecore / EA45S
Batteries / Eneloop ‘PRO XX’ AA _ (HR-3UWX min 2400mAh / 11-05-EE) _ Batteries fully charged, rested over 24 hrs. then installed.
MarioP, I have had no issues with the latest EA45S’s I have bought. But that being said, in the last few days the first one I bought, about a year ago IIRRC; developed a problem.
It comes ‘On’ in ‘Low’ when the ‘Off/On switch’ is pressed. But when the ‘Mode switch’ is pressed it turns ‘Off ’. :question:
I assume something has gone wrong with the switch, but that is just a guess.
I have the reflector out, all the solder joints & wires I can see appear OK. I am now trying to figure out how to get the switch, boards, LED, & the rest of the “innards” out (without destroying them) to check what I can’t see.
This is the first Nitecore of many I have ever had any problem with at all.
So, when I get the “innards” out and check them maybe I’ll know more.
As far as your’s goes, sorry; I have no idea my friend. Good luck though.
IF I find out what is wrong with mine I’ll report back. Maybe that might help you.
Taking the batteries out and then putting them back in (or just taking the tail cap off and then back on) should clear any lockout mode. Let it sit for a while without cells to make sure any caps drain down, then try it again. Good Luck.
I’m not 100% sure what the results mean, but are those results considered good or bad after two months? I have this light as my nightstand light, so I wan’t to be sure it’s gonna go when I need to use it. Granted I charge the batteries up every few weeks just to be safe.
A more knowledgeable person may disagree, but I would consider this good. :+1:
In 65 days of being in “Lock Out” with no (zero) use, the four batteries lost an average of 0.09425v each. (less than 1/10 volt.)
That comes out to 0.00145v per day.
Voltage loss in NiMH cells is going to occur over time, even for low self discharge cells, so your measurements don’t really say much about how much the light is draining them.
To really see how bad any parasitic drain may be, you could get two sets of 4 cells, test them all for capacity, recharge them, then put 1 set in the light and leave 1 set out of the light. After a period of time, test both sets for remaining capacity and see how much of a difference there is between them. They’d both should have the same amount of self discharge, so any difference in capacity could be attributed to the light.
I agree, that is a great idea & I may do it some day… if someone else doesn’t do it first.
Right now I am just interested in seeing how long it will go and the light still be usable if needed. And I know there are many variables in that, how long to be used, mode etc., etc.
