Back in late december I purchased the Olympus E-P3 bundle from Adorama which on top of the original olympus battery also included a spare Power2000 1800mAh BLS-1 replacement. Usually I'm a little paranoid with the shape of batteries (mainly cuz my old macbook gone thru 2 "bloated" batteries). Anywho, this spare battery I noticed has a very slight buldge, it works and last as long as the olympus if not longer, but if I were to hold a flat object accross the center of the battery like say a ruler only about 50% of that surface may come in contact with the battery itself with the rest having a small 1-2 milimeter gap showing that there's a slight curvature accross the surface. As such I haven't had this battery for a year year (purchased the bundle on 12/27/2011), so I'm wondering even though the battery appears to be working I'd like to play it safe and contact Power2000 regarding a possible warranty exchange etc, but I can't find their website, as such I emailed Adorama with my order number (which is remembered as I signed up with an account on there) asking them for advice (haven't heard back yet). Your Thoughts?
