My answer is - no. If it isn't Kyocera OEM, and I'm sure it isn't, then don't do it. From what I hear you take a good chance of damaging your 7135. Check out Dan's in the Smartphonesource Classifieds and get an OEM backup battery or a car charger or Car kit if you're driving. Dan's prices are much lower than anywhere else and his service is great.
