10440 protected batteries?

[Cisco]

???

Looks like a ridge, to me...or am I missing something?

The ridge would be on the negative end, you would see the pcb pattern on the negative end also not the metal shell. These don't appear tp be protected.The fact that the shrink wrap is folded over the negative end would give you the impression that they are protected and they are almost 1mm longer then 10440's I have

It states Short circuit and over-current protection. If they were protected it would state Over charge and under/dis-charge protection.

Almost all trustfire and ultrafire batteries are overrated, these are more like 350mAh

Someone would have to buy them and cut the shrink wrap open to be 100% sure but I doubt it very much

That's what I thought and is why I didn't order any, I only use protected. Thanks to all for the Good Information, I learned something tonight.

I'm.......................honoured??? or worried...yeah, worried, that's it!

Fill, I was just stalking you. I stalk you and TDM mainly. Depends on my mood and which day of the week.

Thanks everyone for their comments.
Well I ordered them yesterday and currently am using unprotected 10440's in my Cisco laser mod and also in my USB passthrough, so its not like it is any different then what I have now. The one aspect is possible failure as noted by Kelemvor. Hate to cut into a new battery but I am willing to just see if they might be protected (will it still be usable without the wrapping?)
Before I do so - any precautions before I disassemble?
I am not ignorant when it comes to electronics, as I write automotive electrical diagnostic manuals for a living, just have not dealt with Lithium Ion batteries and their precautions except for a 300 volt hybrid vehicle - and that is a whole different ballgame.

Just to help calm the fears of people who will not use unprotected batteries.

Every E-cigar on the planet, since day one uses unprotected batteries.

Ever heard of a problem?

Lets not also forget the Janty stick uses the same battery as standard.
I've never had a problem with this batt.
Over rated in some cases yes, but problems no.

Hey Garry,

The only difference is the Janty stick has battery protection built in, the e-cigars don't.

Yea, they claimed protected batteries back a while ago, at the time, from the pictures there were obviously not-protected. There new pictures indicate that they might actually be protected. If they are, they will be 1mm to 1.5mm longer

But, It doesn't matter I actually have a small custom made order of protected 10440 batteries coming this week, we will see how well they do. I wouldn't put them on the market without testing them first.

How did you get this done? Because I could *really* use a source for protected 18350's, which should be trivial enough to do (same diameter as the commonly protected 18650's and 18500's). It would simplify my life *so* much.

Seeing as how the Janty Stick has the protection built in and so do most of the other battery chargers, I don't see this as being a real issue. I think common sense and general care when handling/charging these batteries is about all that is really needed. Everyone says not to walk off and leave your batteries charging. I make it a habit to only charge my batteries in the charger when I am sitting right there with them. I have however went to bed on occasion and forgot I was charging batteries. So far I have not had any problems with them at all. I have since bought many more spare batteries so that I can limit my charging to mornings when I am not likely to go to bed and forget them. Disasters can happen with any battery. A good example of this is trying to recharge standard alkaline batteries. This is definitely not a good idea! Back to the common sense thing there.

in the text it says that it´s 2mm longer than normal 10440, so ther might be something about it.

One 10440 I had burned out. Plus the protected ones are always such. PCB.

That said these are great replacements for AAA in anything that can handle, and is improved by the extra juice, i.e. flashlights. My headlamp takes 3 AAAs, I put one 10440 in to add brightness.

 

[Houdini]

My VAPRE 51 came with protected 10440's. They would hardly fit inside and one of them had a small piece of the protection circuit sticking out of the shrink wrap and caused a little spark display. My solution was to tear off the outer layer of shrink wrap and pull the protection circuit off. Here's what it looks like if anyone's interested.

Stupid question.

The Ruyan E-Cigar (701) uses 10450S (3.7v 360mAh) batteries. I can´t seem to find them for purchase anywhere but Ruyan-selling sites (shipping would cost more than the battery itself).

Can I use 10440 instead? I don´t know if they are the same size, but they sure look like it.

 

[Ez Duzit]

The 10440 is 1mm shorter.

In the RC world (radio-controlled), Li-ions are often charged in ceramic bowls, just in case. At flying fields it's not uncommon to see wires running out of a vehicle (full-size vehicle, that is) to an ammo can a few feet away. Charging Li-ions inside a car could be bad! That said, the only time we ever see problems with these types of batteries is when re-using one that has followed a plane into the ground, vertically. ;-) In other words, Li-ion-related fires and explosions are mostly due to a damaged battery. So, unless you've thrown your battery down on the pavement... 8-o

Also, the batteries in this thread have quite a bit less "poop" than RC 10C or 15C Lipos, too.

Oh, and the biggest hazard with these smaller batteries is getting a pair (or more) of them mis-matched, whether due to mixing, or pairing with a defective, dying battery. Single battery usage is pretty safe.

I have Protected 10440's from Madvapes and they have the ridge around both ends. I will check the voltage as I use them. I assume someone finally decided there was a market worth tapping for them. Would be interested in any other information...
