Ok, here is my summary of the extended battery:
Fully charged the extended battery Thursday night and unplugged on Friday morning at 9 AM. Decided not to recharge the battery to see how long it would last. Its now noon on Monday and I still have 15% battery remaining! Needless to say, I'm quite pleased with the battery life. I am an email/message addict and constantly am checking email, etc. I even used verichat for half the time! However, I did have bluetooth off (except for a 30 minute conversation), so this may have perserved some battery life. I consider myself a heavy power consuming user (+1000 text messages a month, corporate/personal email, internet browser, verichat, bluetooth) so I'm very impressed with the extended battery power life!
On the bad side, i found this battery is NOT compatible with the plug-in battery charge (http://www.shopblackberry.com/_black...8C66PHRLTDADD6)
. I did check the contacts, fit, etc - the battery fits in the charger perfectly, but the RED light comes on instead of the usual charge color (amber/green). I saw RCG's post stating that it is compatible, but mine does not seem to work (only rechargable via phone charging).
