The Mythbusters tried out the cell phone/gas station trick. Couldn't get it to so much as flicker. The "myth" of exploding gas station was definitely busted.
Li-Ion batteries, on the other hand, do fail catastrophically. There are valid reports of counterfeit LI-ION batteries with no/faulty protective circuitry. You should stick with a reputable source for batteries. You get what you pay for.
Which is why I come back to my point that "you get what you pay for".
Our examination of a "no-name" battery shows that people can build a battery cheaply. You don't put in the protection circuitry or place a poor quality circuit board in there and you save money. But you do see the results on TV (and in law suits).
LiPo Cells become very volitale if they are discharged past a certain point and then a recharge is atempted or if they short out. The good news is that most regular bats are single cell where as extended are probably double. Anyway they can surely blowup if they don't have a cutoff switch.. LIPO cells are becoming very common for rc hobbiest have a look At this link it shows some that blew up durring charging and gives many many instances of people talking about them exploding.. So it is worth thinking about make sure you purcahse good cells.
As for the constant thread craping with images I have found the attached image to be the best cure for that Bosoc. Then you are only subjected to those worthless posts when someone qoutes the useless posts.. X
Li-ion batteries have different chemistry than ni-cad or alkaline ones. A short circuit can cause them to explode, which is why they need internal circuitry to make them safe.
As far as the UL mark: the battery itself is bogus... these people have no qualms about printing UL-approved on the outside of it!
==============
Hi, Im new here....you mention internal circuitry to make them safe, does that mean that if you were to carry one in your pocket with keys or coins then if the terminals got connected it wouldnt short circit but just cut out?
Just thought I would throw this little tid-bit out there.
This past week I was watching the news about cheap 3rd party cellphone
batteries.
Apparently these manufacturers are selling them cheap because they do not
include the electronics to shut the battery down if it is shorted or overheats.
It showed a woman, whose hands were bandaged due to burns, from using
one of these batteries in her cellphone. The device got hot and exploded.
So, for those skeptics out there, this is for real.
Yeah, the batteries work find, but if they ever experience an internal short or
external short, well, can you say "melt down"? This can apply to the cheap
no-name axim batteries we are seeing on the market.
You can be carrying a spare battery in your pocket with change and this
could short out the battery. Can you say "OUCH"?
They mentioned that there are not only 3rd party batteries, but rip-offs of
what appears to be original manufacturers batteries.
So, my point is "BUYER BEWARE".
Is it really worth it?

Hi, i have a question for you...is it possible for batteries to have internal circuitry to make them not short-circuit if say the terminals were to get connected? e.g. would my mobile phone lithiom ion rechargable battery short-circit if the terminals were connected by my metal watch strap? or would some internal circuitry stop that happening? If internal circuitry is present would it stop the short circuit and stop the battery from working in future?
A fuse will melt and disconnect the circuit in case of a short circuit. The fuse must then be replaced for it to work again.
A circuit breaker or PTC self resetting fuse will automatically reset once the fault is removed. A few batteries have reset buttons that must be manually pressed to reset the internal breaker.

Does anybody know how to tell if a Dell Axim batery is counterfiet? I recently purchased a second batery for my Axim from Ebay. I immediately noticed that the one I just purchased was made in China while the other was made in Korea. After reading this thread I looked even closer at the bateries and noticed some major differences. They have slightly different casing and slightly differnt stickers. The thing that stuck out the most though was the fact that they had different UL numbers. The one that orrigonaly came with my x50v(bought new on Ebay) has this number: MH26511. While the one I just bough has this number: E204007. Does anybody know if either of these are counterfiet/ Do these numbers conincide with anybody elses? I also just noticed that they both are A00 but other numbers are also differnt. Whatever anybody can tell me would be appreciated as I don't want to blow my hand off with one of these things. or get torched in any way
The one that orrigonaly came with my x50v(bought new on Ebay) has this number: MH26511. While the one I just bough has this number: E204007.
The MH26511 is the UL registration for Samsung SDI Co. Ltd (the maker fo rthe battery cells) while the E204007 is for Sanyo (Taiwan). The PDA battery is not UL approved only the battery cells within the battery carry the approvals. But, if someone in China is going to counterfit a battery, adding these numbers make no difference. You would have to trust the seller on eBay. We sell these batteries from Dell and are made in Korea with the UL number E211281. These are from Dell. So, it is hard to really know if you got knockoffs or not.
I have a friend who works for a company in China that makes Li-ion batteries. They claim to be the world second largest Li-ion battery maker. The No.1 seems to be Sanyo. Anyway, one day I told him that I always bought cheap battery and never had a problem. His response was some sentence in Chinese, which means the ignorant is the bravest. Now, I won't consider those cheap no name Li-ion batteries anymore.
Of course, I still like those no name generic stuffs. Just got a no-name hard case on eBay and I love it. :)
