Greetings one an all. I just purchased the extended battery 2600MAH battery from Seidio and it rocks. I now charge my phone every 2.5-3 days instead of nightly or sometimes twice daily. Cost is <$60. The battery is slightly larger and arrives with a new battery cover, rear phone access cover [one and the same]. It makes the phone a little bulkier/heavier but STILL fits my current case [not the one provided by BB/Verizon]. I include the link if you're interested. 2600MAH EXTENDED BATTERY FOR BLACKBERRY 8800/8820/8830 - BACY26BB8800-RBK
