Nitecore E4A completely drainning my batteries in standby mode. Normal?

Well, compared to the SWM D40A (1-2mA), the EA4 is low Big Smile

Someone else did a detailed analysis of the D40A and found that that high current was only for the first few seconds, after that standby current dropped to very low levels as advertised by SWM.

SWM has such a high drain?

It looks better though (to some) so it doesn’t matter. >.<

Do you have a link to this analysis?

Thank you. Feels so much better now. SWM couldn’t be losing to NC in the electronics design department.

How bright is bright enough...

I waited for about 30 seconds or so, as it was very slowly dropping during the first 10 seconds or so. After that it didn’t drop any more.
I’d be interested in seeing where these results were reported as well.
Edit: Well, there you go. I just tested the D40A again and it’s behaving as described above. After about five seconds, the current drops down very low.
Standby: First five seconds, 1.4mA. After, 11uA.
Locked out: First five seconds, 1.4mA. After, 313uA.
I’ll update my review!

Welcome the night.

Why is the current draw higher when it’s locked out? Shouldn’t it be nothing, or at least lower than standby?

 I get the low battery indicator on my EA4 after about 2 weeks in standby mode using standard eneloops. I have the older version according to my pal Relic38 which might draw more current in standby mode than the newer models

Thanks Pulsar! I lost my job a couple of months ago and I was in a deep depression over it. I was angry at the world to be honest. I'm feeling alot better now. 10 more months and I'll be collecting my social security. At least I got something to look forward to!

Thanks for finding that bumble, I couldn’t remember which review I’d read it in.

Also I’m glad to hear that you could replicate those results relic38, I really like my D40A but am definitely not a fan of parasitic drain.

Slewflash, I have no idea, but I suspect it has something to do with the MCU configuration for the lockout mode of operation. I agree, lockout should be lower than standby. However, SWM’s main purpose for lockout mode is to prevent accidental turn on.
The physical lockout method (unscrew the body abou 1/4 turn) is much more effective at cutting parasitic drain; 100% Smile
Good to see you back on Glenn!
