A year ago from this day (roughly) i got an i-mate jamin, the seller also purchased a new a Cameron Sino Brand 1200mAh, 3.7 V battery.


After a year my phone.. my phone didn't turn on one day... wouldn't charge.. and when i opened up the back cover i could smell a mild burning plastic odr.




Has anyone had any experience with this brand of battery, how long has yours lasted, has it ever caused any damage to your phone?




Im not sure whether its the battery that's dead or my phone..



Any advice or past experiences would be much apprecitated thanks! :)

I've got a 3Ah battery from the same manufacturer for a different phone. It is now 11 months old and seems to be working fine. The manufacturer makes cheap batteries which are not what their specifications say, but usually do work. The thing is few people know the limitations of Li-Ion batteries. There are also a few variants with different limitations. All of them except LiFePO4 (lithium iron, not lithium ion) will generate oxygen when they fail so if they catch fire they are hard to put out. But LiFePO4 has a lower voltage and is not a replacement option. I am an electronic engineer and research Li-Ion technologies recently (for work), and can tell you there are so many safety risks involved that from now on I'll be buying them only OEM.

If there are no flames then it will not cause damage. The only possible damage is when the battery spits out flames... Lithium polymer is a laminated battery so there should never be leaking electrolyte.

Few people know about the danger of lithium batteries. Have a look at You Tube, there are lots of videos on cell phone batteries. They are fine as long as everything goes well, but it gets scary when things go wrong. Lithium polymer is popular due to it's low cost to manufacture, light weight and ideal voltage for electronics. Safety issues are covered by the warning saying do not store above 60 degrees Celsius. Don't ever leave it in your car on a sunny day...

You will find lots of Cameron Sino and other cheap batteries on eBay. A quick search suggests that the OEM battery is made by DynaPak who is also an OEM supplier for Samsung, Apple and HTC. Right now there are 2 for your phone on TradeMe for about $36. retail price is around $90. TradeMe also has the higher capacity batteries but when there is not even a brand name or country of origin on the battery...

Often "extended" batteries are cheap stuff. Known brands like Sanyo can usually be trusted to include the proper safety features. If you know the brand name then you can usually trust it. If you don't know the brand name then you need to do some research on it.
