It has always been good for two full days of heavy use, for lighter use I have gone as long as five. I purchased it because of the great experience I had with the large Seidio battery on my Palm Treo. After 14 months of use I am thinking of buying another one.
Just what I wanted

This battery is exactly as advertised. It fits perfectly in my 8830, and lasts longer than my original Blackberry battery. Dont buy the negative evaluations, buy this battery!
Come on, really guys?

Are you guys even using a 8830?
I have this battery and it last longer than the original and *doesnt* give it any extra bulk, it is the EXACT same size.
It is a no brainer, but only to invest in it.
Not QUITE "OEM-sized"

Cons: Too thick! Causes 8800 battery cover to bulge, which means eventually breaking
It baffles me why a company would make a battery, as a replacement for an OEM battery, and make it too thick.
I got it, and was really looking forward to the extra life it would give me. I put it in, and had a hard time getting the cover back on! Eventually it worked. Next day, as I was using my phone, I noticed the back of the phone had an extra edge to it! Turns out it was the battery causing the cover to bulge out. So I took it out and compared batteries side-by-side, and it was definitely thicker!
Id put up with it if I knew the it wouldnt eventually cause the door to break. But lets face it, if you put constant pressure on a piece of plastic, eventually, its going to snap! So Im returning it and going OEM again. What a shame.
DO NOT BUY!!!

Cons: Only lasts 1 day
Save your money!!! Buy an additional OEM regular life battery instear of this "long-life" ! I charged this in full and it only lasted ONE DAY!!! My OEM battery that came with the device lasts 2-3 days. To me its a "no-brainer".
