This morning I ordered a new battery for my BlackBerry Bold 9650 because I was finding it a challenge to get through half a day without charging. I am one for finding deals and normally I shell out $40 and just buy a battery from Seidio. I shipped Robb the battery form my old Storm when he was having battery problems as it made no sense to purchase a battery for $40 when you can get a new phone at Amazon for 1¢.
If you need a new battery I would check and see if this model fits your phone as $3.33 with free shipping is the right price for me. I tend to get frustrated with my phone before it dawns on me I need to purchase a new battery.
