AIS Mobile Battery Kaboom

[skippybangkok]

Seems a lot of phone batteries in the news lately...

[h90]

scary when it happens in my trouser......won't use the front pocket anymore.

Did it happen during charging or during using the phone for a game or movie (or something that takes lot electric) or just on standby?

Hahah...... Happy vasectomy.

Wife sent to me from friends post, no idea if user abuse or poor product quality.

Probably cheapo Chinese batteries, happened before in a bank with an S3:

I notice EMS has tightened restrictions on shipping phones with batteries out of Thailand. I tried to send a phone to friend in Philippines from post office in Bangkok and was told "Can Not!!"

Fires in airplane cargo holds is a legitimate concern.

Yes the vast majority of consumer electronics are produced in China nowadays but I am sure Chicog is referring to unbranded aftermarket batteries as opposed to OEM.

Quite likely that AIS branded phone fits in the former category.

I'm not anti-China, in fact I am involved with manufacturing (not electronics) there. But there is no comparison between an OEM supervised manufacturer and one that produces products that compete mainly on price.

Heck, just because a seller says the battery is brand name/OEM doesn't mean it's true with all the Chinese made fake brand name/OEM batteries, microSD cards, memory, the list goes on forever that can come with fake OEM labeling and packaging.

All you can hope for is it's a "quality" fake...and by quality fake I mean a well made fake equal to OEM standards/specs.

I've had three batteries "balloon", two on low priced tablets (ONDA and AIGO) and one copy phone. All three batteries would qualify as "cheap Chinese".

Heck, I very recently bought two "Genuine & Original Samsung" batteries (according to the Ebay ad) for my S4 and the wife's S4. Both our S4 batteries were around 2 years old and just not holding a charge like they use to...they had far exceeded their normal 500 full discharge cycle life. Bought the new batteries off an Ebay seller in the UK who had nearly a 100% Ebay reputation and was selling these batteries like mad...over 500 sold of this very particular battery plus thousands of other batteries. The batteries arrived quickly...and looked as genuine as the original Samsung batteries which came with the new phones.

However, both new batteries had identical serial numbers (not to be confused with batch number)...serial numbers for batteries are suppose to be unique...a different serial number for each battery. The batteries were in all probability fake due to having identical serial numbers...I got a refund but got to keep the batteries. Unless I had bought two batteries I would have never been able to notice the batteries did not have a unique serial number indicating a fake.

However, we are using both batteries in our S4's, battery life is now back to like when they were new...hopefully they were quality fake Samsung batteries....but I will post pictures if the fake Samsung batteries do smoke our phones.

So when buying a battery at the store you might want to ask the sales person to show you two of the batteries so you can see the serial number printed on the batteries. If they have identification serial numbers then they could be fake if it's indeed true each battery's serial number would be unique (and once again, serial number is not to be confused with batch number where many items are made under the same batch number).

It can be so hard now days to know if you are getting an original or fake battery. Yes, yes, you can always go to a Samsung store, Apple store, Lenovo store. whatever brand name store and pay ridiculously high battery prices or you can buy from other places. For me, I place high value on price but at the same time I do try to do my best to determine if the product I'm buying is a quality product and safe to the best of my ability.

So far with all the laptop/smartphone/tablet devices I've owned only one has had the battery puff-up/fail big time. And that was the two year old battery in my Onda V971 tablet I talked about in another tread. I was able to get it removed before it caused any damage...it continued to slowly puff up like a little ball even after being removed, but it never got hot, never exploded, never caught on-fire on anything like that. I ordered a higher capacity battery replacement off AliExpress...supposedly a LG made battery but who really knows....it been installed for X-months now and I have tablet run time far in excess of when the tablet was new....but who knows, it might puff-up into a ball at some point.

Summary: no shortage of fake and low quality batteries on the market....buyer beware to the best of their ability....that's all we can really do.

That's a great tip. Thanks for posting it.

Generally you get what you pay for. If you buy a cheap Samsung or Nokia etc, quality of battery would still meet a standard, but going down the no name route is asking for issues
