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

This might be the most accurate statement in this thread, LOL.

Just received a few flashlights from FastTech. Among them a Nitecore EA4W. Flashlight claimed 6.3v when the batteries were first installed. A few hours later, including about two minutes of actual runtime, and the flashlight claims they are down to 5.7v. Personally, that seems excessive.

And just for the record, that UI is way too complicated, imho, for someone who was lots of lights. I mean, how am I every going to remember all that after not using the light for a few weeks?

Yea but they have MAP that makes them top shelfā€¦ā€¦just ask them :bigsmile:

WAIT.

While I havenā€™t noticed any excessive drain on my EA4, I did have a problem with a EC25 that would run the battery down in less than a week when not in use. I took it back to GoingGear and they replaced it on the spot and now Iā€™m not having the problem with my new one. Seems to be just fine and I like both lights alot. I also like my D40A because the quality is a little better than the EA4.

SWM has such a high drain?

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.

It looks better though (to some) so it doesnā€™t matter. >.<

Do you have a link to this analysis?

Thank you. Feels so much better now. SWM couldnā€™t be losing to NC in the electronics design department.

I waited for about 30 seconds or so, as it was very slowly dropping during the first 10 seconds or so. After that it didnā€™t drop any more.
Iā€™d be interested in seeing where these results were reported as well.
Edit: Well, there you go. I just tested the D40A again and itā€™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.
Iā€™ll update my review!

Why is the current draw higher when itā€™s locked out? Shouldnā€™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

hey! welcome back glenn!

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!

yeah, loosing a job sucks hard... glad your pulling out of the rut though.

Thanks buddy, I appreciate your support :)

Thanks for finding that bumble, I couldnā€™t remember which review Iā€™d read it in.

Also Iā€™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, SWMā€™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% :slight_smile:
Good to see you back on Glenn!

Thanks, Bumble! Itā€™s nice to see you posting again, atbglenn!
