Stop getting ripped off!!!

Shaped like Rockets?

What you talking about Willis?
(BTW the blow out disk in the bottom is larger than the cell, with vents, and the inside is insulated)
I've moved on to bigger stuff

I read somewhere in the news, a guy in florida smoked a e-cig and it blew up in his face. So that battery must have been a really cheapo to the maxo!

Or it could have been a High "Quality" Battery that failed in a mod that had Little or No Venting.

ALL batteries can Fail. It's if they do, what are they Inside that makes a Huge Difference.

It could have been quite a few things. Nobody here really knows for sure. And as the days go by the likelihood of finding out diminishes.

From the site we have this;
http://www.e-cigarette-forum.com/fo...61-exploding-mods-update-february-2012-a.html

Per that thread all reported explosions have been from mods using 2 (stacked) batteries. Not sure about this latest one yet.

But even the best Li-ion batteries can explode if over/undercharged. It's also possible to buy these batteries without any built-in protection increasing the chances of things going wrong. The best battery on a cheap charger can get overcharged and blow up. Either on the first use of them or while sitting in the charger.

Lots of these 'cheap' Ultrafire, Trustfire, xxxxxfire batteries are just relabeled/used or factory second batteries. Mostly they don't get anywhere near the mAh that's on the label. Many are DOA but mostly just weak and wore out batteries.

This what I find Very Disturbing.

It doesn't take much to peel of the Wrapper of some Factory Second, or No-Name Battery, and then Slap on a Wrapper of your choice.

And a clue about this thread in particular. First the mAh of 3600 on these batteries when the best ones are only 3100. That and the label colors are off. To get two for ~$3 just pushes the limit of reasonableness.

Title of the thread is 'Stop getting ripped off!!!!!', yet this is a prime example of just that.

 

[Riverboat]

Those batteries are rated 3600 mah and are really alot less then their mah rating, plus they are UNPROTECTED!!! .... Stick with the AWs, they out perform all others under load tests.... Batteries dont cost that much to risk your safety using unprotected ones..... A atomizer puts a HIGH AMP load on a battery thats why you need the protection or a safe chemistry like an AW IMR........... Plus that website aint so cheap, look at the Ultrafire WF-139 charger price you can get it for about the same price @ SuperTmanufacturing. so those cheap batteries are just that CHEAP BATTERIES of low quality....you get what you pay for!!!

How high?
and which one do you suggest?

 

[VapoVamp]

Afternoon Rocket! I'm soooo glad your here @ ECF! You make my day as always! Thanks for the giggles. Where do I get a ???/Oh, never mind...makes me want to VAPE

How high?
and which one do you suggest?

 

[ShankUO]

I agree with the people that state to buy protected more expensive battery. You get what you pay for. I'll spend more money on reputable protected batteries and charges. My family and my face are worth a couple extra dollars.

 

[Rocketman]

Being ripped off is paying almost as much for a bargain basement product as you would for a high end product. Which one you choose is just a choice. Of course a higher quality cell is better.

Let's say you already have a mod, charger, everything but need one more battery like really bad.
Try this exercise in ripoff avoidance (just picking 2 cells for an example):

1) Find the highest and lowest advertised price for a genuine (hopefully) AW IC protected 2600mah 18650 cell. One cell, plus shipping.

2) Find the highest and lowest price for a genuine (ha, so what) Ultrafire protected 3000mah (as labeled, not real mah) 18650. One cell, plus shipping.

Just shopping, not recommending. Do the exercise and you may be surprised at the range of prices.

 

[soybean]

I'm sorry but cheaping out on batteries is a good way to blow a hole in your face eventually.

Be cheap on atomizers/cartos/juice if you want, but please for the love of god get high quality batteries.

You're basically sticking a chemical bomb in your mouth.

its about time someone said it.

That's simply is not true, and is typical of the anecdotal evidence that gets passed around ad nauseum, that is then quoted as fact.



@ stephpd

The better batteries stay up over 3.8 volts for a days use

Also untrue, unless of course "a days use" is 1/2ml of liquid with a 3.5Ω load and even then that's stretching it. Unless you are referring to a 4000mAh IMR26650. Are you?

Some of the cheap ones don't even start above 3.8v, or they drop off from 4.1 to 3.8 while checking them out.

Dropping from a fully charged 4.2V to 3.8V is quite normal for any 18650 Li-Ion made. And the Panasonics (fine cells that they are) drop voltage quicker than many of of their competitors.

 

[Mrtrucker40108]

we've been using unprotected batteries in devices that range from hanging on our hip to hanging in our ear canal ??

why the big deal about protected batts all of a sudden ??? if these are any good at all,i'd buy and use

Ask that guy in Florida about unprotected battery. Oh yeah, he can't answer you, he blew his face off.
My wife vaped my mods too. No way would I Rick that happening to her. I'll spend the insurance money and buy from a reputable dealer selling known quality.

Typo hades... Lol. Frikkin iPhone.

Calling me a liar?

That's exactly what I'm seeing, by checking the voltage on my Provari while using it throughout the day. I'm normally running at 3.8-4 volts with Smocktech 1.7 cartos in a Chibi tank. The AW IMR's and the Panasonic rebranded last all day and maintain over 3.8 volts.

But I have some Trustfire and Ultrafire that while testing the battery on first installation drop from 4.1 to 3.8 while performing that test. Some won't even start at 3.8 but more like 3.5-3.6 on first installation.
They were purchased as new, don't have many recharges on any of them and this is what I've observed.

Go ahead and call me a liar again.
I know what I see.
Far to many of these xxxxfire brand batteries are not worth it and certainly not what they're advertised as. Most of these won't even last a day before stopping on low voltage. Some as quickly as a couple hours of intermittent use.

 

[Rocketman]

Don't put an Ultrafire cell in a Provari, or in any boost mod.

Don't try 1.7 ohm cartos with an Ultrafire battery.

You try and vape an Ultrafire boosted and with low resistance and the load on the battery is excessive.

stephpd, You are not a liar. But do you know what you are doing?

You are trying to draw the absolute maximum current a cell like that can provide (2.5 amps). That is asking for a problem. There are 'medium performance' cells at 'medium prices' but the Ultrafire is not for 'high performance' applications.


If you paid more than $5 (give the vendor a little profit) then your reputable vendor ripped your off. He was trying to guide you to a slightly higher priced cell, and you took the low road. If you paid $3 to $4 for the Ultrafire, then you took the low road by choice.

I've been poking at vendors selling Ultrafire Big Red cells sometimes for over $10 EACH. Am I stepping on toes here? Some folks may be upset about paying that much.
Sorry if that makes you feel bad (not really )

 

[Rocketman]

Here's a piece of advice to keep from getting ripped off:


Don't buy a counterfeit Li-ion cell.


(also don't buy a cheap car, you get what you pay for)

 

[Rickajho]

The ones he bought aren't even one of the standard colors; (they're Blue with white and red stripes)
http://www.tmart.com/37V-3600mAh-UltraFire-18650-Liion-Rechargeable-Battery-Blue_p138441.html

Two 'high' amp batteries cheaper then many of the lower amperage batteries on the site should give you a clue.
http://www.tmart.com/search.html?new_add_order=3&layout=grid&q=18650+battery

And what I find truly scary is I couldn't find a single use of the word "protected" regarding any of these batteries. Hell, I couldn't find one that even looked like a protected cell. At least a place like DealExtreme.com knows the difference, or at least bothers to report it in their product descriptions.

Start getting ripped off!!! Please. Or at least know what you are buying.
