Normally I stay away from Aftermarket batteries, I had 4 OEM batteries for my Instinct but they cost much more so I'm wondering other then the possibility they might suck, is there any reason to not use them? Looking on eBay, you can get two aftermarket batteries (1500mah) AND a stand alone charger for like $10~13 dollars shipped from Hong Kong. I really want an external charger anyway, I use the one that CAME with my Instinct far more then I use my phone plugged into the wall to charge. Thoughts? I just don't want something thats going to fry the phone or explode and kill me like that one guy in China with the crappy lipo cellphone battery that made the news!
