Nitecore Tip: SEVERE Parasitic Drain in Lock-Out Mode !!

ETA: https://www.reddit.com/r/flashlight/comments/53c8mc/nitecore_tip_confirm....

There are reports of Nitecore Tip going dead after being put in lockout mode. I fully charged mine locked it out and didn’t use it for 3+ days. Was carried in very loose cargo shorts pocket so no chance of accidental activation. Results, stone dead. Hope this isn’t wide spread. If you havent’ checked yours out yet you should. Nitecore Store is looking into it and offering free replacements already. I bought mine from A&A. So hopefully it’s warranty return won’t be a problem. Not much use dead from lockout mode. That’s why I bought it for the lock out mode feature. Geeesshhhhh…said I’d never buy first run of anything any more…win some lose some.

That sucks! I tried mine, and it still works

Edit: I originally thought you meant it wouldn’t come out of the lock mode. I’ll lock mine and see how long it takes for the battery to drain. So far I’ve gotten a week of light use on a single charge without using the lockout mode.

It’s recharging right now. Battery seems fine as it’s coming up bright nicely. Good ole Lith-Poly.
Won’t be locking it out for a while to see how it lasts.

I’ve been reading on the other forum that there might be a problem with high battery drain in the lockout mode which makes no sense. Nitecore is investigating it.

Is Nitecore losing it?
First the shoddy update of the i2 charger ( http://lygte-info.dk/review/Review%20Charger%20Nitecore%20Intellicharger... ), now this.

Weird that a top tier company could have such a couple of flops, that charger and the lock-out drain issue.

Their TM-03 and MH20GT are awesome lights.

The following FIVE people in this thread*2016*-New-Nitecore-TIP&p=4965770&viewfull=1#post4965770 are reporting short battery life when using lockout

Had them both locked out during this time.

thank you for sharing your unfortunate experience

The explanation doesn’t make a whole lot of sense. It smells like a firmware bug. Like if you put the light in lockout mode the MCU doesn’t go into it’s low power state, but stays awake and discharges the battery in a few days. If you leave it alone it goes into the lowest power standby mode until the power button is pressed.

It’s trivial to put the MCU into standby and have a lockout feature. The MCU will still wake up when the button is pressed, but doesn’t turn on the LED because it’s in lockout and instead goes right back into standby (yes, pressing the button a lot while it’s locked out will affect the battery life slightly). If the power button wakes up the MCU, the light is in lockout, and the other button is also pressed, exit lockout and turn on the LED. It’s a pretty simple state machine…

I will be waiting for a fixed v2 TIP myself and skipping the beta.

Mine is recharged and operating nicely after the lockout mishap. If battery charge as recently reported lasts a year without locking it out, GREAT,,,,. But what’s the point of an advertised lockout that KILLS your light?? I think Nitecore has dropped the ball here on a proper lock out system that could have made this the perfect keychain light. Flawed, but I still like it overall.

question: could this just be a glitch on some TIPs, or is this across the board? Anyone?

I’m testing mine now in lockout. So far no problem after 6 hours. I’m going to let it stay in this mode for the next few days and see what happens. I will report back here then.

I’m pretty sure most all will have the problem according to the initial Nitecore team response as reported over at CPF. Really though, hope I’m wrong on that. I also hope NiteCore will correct this in next TIP series, just as they did when they implemented a lockout on the later run of the TUBE. First run kept turnin on in pocket.

It won’t be in 6 hours for sure. Give it a few days in lockout. Monitor it in a couple days to see if those red led’s blink indicating low battery. I never looked at mine. Just dropped it in night stand drawer at end of each day. Was reading the bad review on CPF and decided to check mine. Yep, It was as dead as a door nail.

Nitecore is long known for high parasitic drain, but why haven’t they fixed this after so many years?

will test mine when it arrives.

The MH20GT claims to have extremely LOW parasitic drain, lasting 24 months with the beacon off and 12 months with it on. Lockout on this one though is physical, a slight break of the tube to head contact with a 1/4 turn. This was one step forward from Nitecore that prompted me to buy this light and having also just ordered the TM03 when this TIP was announced I didn’t pounce on the little light.

My Caveman and EA4 were horrible though, never keep cells in em anymore and they’ve been relegated to an offsite shelf because of that issue.

I did not know that, but Im new, so I did a quick search and immediately found many threads that report that the lockout mode has higher parasitic drain than unlocked, in other Nitecore products.

Do all Nitecore lights have parasitic drain ? My EC11 comes to mind. Tailcap lockout seems to work but it’s been stored for the last month 4.1 blinks when stored, I just checked it and it is now 3.4 blinks.
Have to recharge and test that drain….

I’ve got the NC EA11. But for safety’s sake always unlock tailcap 1/4 turn. Can’t do that with TIP.

Are you kidding me, was it blinking the whole time?

If so, no wonder it ran out of juice.

That is/was a serious design flaw.

Not…..;-) of course v.1 not blink continuosly the battery indicator.
I have asked to Nitecore about differences between V1 and V2. They reply this, but I think they mean this: In my V1 when light is locked if I touch one of the switch, the indicator of battery blink one time. I can suposse in the new V.2 this inidcator not blink when touch one swicht in locked mode.

I’ve wanted this light from the second I saw it, but wasn’t going to jump on board until I saw a review. I’m glad I waited!
Have the version 2 models shipped out yet? If so, where can I pick one up?

Have you confirmed that the lockout fixed model can be recognized because it does not blink when the switch is touched in lockout mode?

yes nitecorestore.com is shipping the ones with the lockout drain fixed. Kitrobaskin has confirmed this.
There are 3 models,

240 Lumen w Nichia 90+CRI ~4500k, and
360 Lumen ~70 CRI ~6000k.

No.
I comment the Nitecore reply to my question.
