I recently got a Seidio extended slimline battery. I only have one problem with it. When I put it into the Verizon charger, it goes in smoothly. When I try to remove it at the end of the charging cycle, it takes a relatively large amount of force to extract it. I've had to wiggle it hard forward and backward before it will let go. I hope I'm not damaging it. Is there a trick to extracting it smoothly? The regular Verizon battery doesn't do this.

I dunno about the extended, but I learned early on that to remove even the regular battery requires that you push it hard from right to left and then lift up the right corner first. There's a kind of plastic latch that holds it in there.
