i buy the non-oem batteries from china. i have no problem with them. i have seem oem batteries explode. overheat. or just be bad brand new. i dont care who makes the battery, just that it works. but they want you to think the non-oem ones are bad so you pay alot for the ones from them. who wouldnt say just whatever to get sales? oh my! my battery is counterfeit, how terrible. better go buy another. i get mine for $.99 including shipping. yall pay whatever. i got spares.
