Imalent DT70 battery contact problem

LED Flashlights – General Info 18650 Flashlights
32

I have two sitting about 3 feet from me the DN70 and 35 ad both are working perfectly. It is a newer company so that could all change at any moment, but I have had the 35 for a couple of months now and the 70 for about a month no problems.

I have had 2 Streamlight Stingers in the last 6 months and both died when they were dropped about 3 feet for the first one during a hunt, and the other was dropped while it was still in the shipping carton so no way to say for sure if it was D.O.A. or when it was dropped here.

Then on the flip side of those I have an old original Ultrafire sk68 that has been beat, dropped, kicked, stepped on and 2 years later it still works every time I reach for it.

I am not outright defending Imalent. I am saying that when I contacted them directly it did take a few days to get a reply but I had no problem with their support.

Any light can have an issue and almost all rate their lumen count far above anything realistic.

I wish they would offer to send replacement parts to customers that have warranty issues and the knowledge to fix it themselves. Currently they want people to ship their light back to China at roughly $50 one way with no insurance.

I was thinking about rolling the dice on a DN70 and hoping I got a good one, but I’m not really a gambler.

34

I did tell them up front that me shipping anything to China was out of the question. I asked if they had any dealer in the states at all that I could maybe order parts or even ship it to them if I had to.

Got it worked out before any of it came to that.

Honestly though it kind of surprised me when they agreed to start including a spare USB cover. I figured well that is a start.

35

If the light is bad when it arrives the issue should be resolved with the retailer, not the manufacturer. One must check the retailer policy to see if the return cost is up to them or to the buyer.

It seems that what’s specific to Imalent is that they don’t sell parts. Warranty is always a risk when buying from abroad, be it from China or the US. Even if the manufacturer does the repair without cost, the return and send back often have to be paid by the client. We’re quite used to this in Brazil…

36

I got a dt70 and my battery holder has 4 large springs. I also have the older version that has the weird looking things that act as spring.
Although they fixes this issue, the springs are very stiff and makes screwing the head quite tight. The older ‘spring’ made a much smoother screw motion of the head into the battery compartment.

37

Any chance you can place a picture? It does sound like you can run the light now with any unprotected raised top/button top cells though.

38

I am thinking of getting this light too, still too many battery problem. I just hoped that they indeed change the spring into more traditional one.

maybe solder each spring to the battery negative itself that should be easier to do :slight_smile:

Here is my spring loaded version. The only issue is that it does not lockout with a spin of the battery compartment like the non spring version. Also the springs are tight, so the rotation of the battery to the head is not as smooth.

41

The original version uses DISC springs instead of the coils springs we are all used to.

42

It is the photosucked problem your photo is not showing. i can live with the non-lockout as long as the battery is equally functional.

Cant you click on the link to go to the page? I have no other way of uploading photos.

44

Since you have both versions, can you tell us if they battery tube is longer or where exactly the extra length comes from in order for it to use the coil springs?

Did Imalent make any announcement about the design change or even mention it in any of their sales pages?

This is the first I’m hearing about it.

45

They seem to be both exact same lengths. Only difference is the spring which pushes the battery up about 3-4mm higher. You wont hear any battery rattle when you shake the flashlight.

46

Did they make their batteries shorter?

The only other way I can see them switching to coil springs is with a design change. You can’t just swap springs unless maybe they use very cone shaped coils that can compress fully flat.

47

I Made a video. https://youtu.be/CiLoNG0wgQw

Battery are the exact same size.

48

Very neat. It looks like those springs don’t compress flat, but do come close to going flat.

Imalent may have also moved that pcb the springs mount to back a little.

Now we need someone to test the new version.

49

This is one of the problems I have with Imalent: they just keep changing things. It’s good to make iterations to make a product better, but it makes it difficult to pull the trigger. Not long ago they changed the finish to a matte finish, and now this…

One of the structural issues these new lights still have is an off set value of the voltage readout of about 0.15V. Are they going to fix that as well or not? Hate to buy the light now to discover in two months they have fixed that as well in the new iteration…

Oh and thanks for the video Bruno28! :+1:

You’re welcome, photo bucket has ruined their business. Used to post there so I could send photos to you guys here. I guess it will be youtube now.

I agree with you on that other issue. My older one is matte finish which is really nice and the batteries when charged show 4.20v and it works perfectly. t
This newer one with the springs shows 4.03 when fully charged. And this annoys me. When I check with a voltmeter its hows 4.20v and even with my nitecore D4 also shows 4.20v.

51

It is the photobucket recent change which sucks…
if i click it, it doesn’t work you have to pay extra so your image can be shared on 3rd party hosting but image link is work so i post your pic to imgur. here we go.

Thanks for the Video. Tempting to order DT70 as long as i got the one with the spring. Gotta ask gearbest or banggood.
