I purchased the seidio 1750 extended battery a couple months ago for my Droid Eris. When I heard about the incredible I was excited to see that my seidio battery was compatible so I wouldn't have to purchase another extended battery. Much to my dismay, the seidio will not charge at all. After I ran it completely out, I plugged my phone into the charger and checked back 30 minutes later and the phone wouldn't even turn on. Was I wrong in thinking this battery would work for my incredible? It works fine still when I have it in my wifes Eris. Anybody else have this problem? Will seidio still replace this battery if it turns out that it is deffective? I sure hope so because 50 bucks is a lot to spend on a battery that is useless to me now. Any suggestions?
