OEM Blackberry Curve 3G 9330 Standard C-S2 Battery
I was afraid to buy a battery for my old Blackberry, because i bought battery before and they were bad quality batteries, but this one its awesome, for my phone just in stand by mode with 3G data active (No chatting, no music, no calls) it last almost 22 hours, using it regularly it last around 12 hours, great product!
