Check Ebay and just put the number of the modem/router in TC8305C.  I just ordered one for $23.49 with free shipping...as opposed to the $35.00 and $5.95 shipping that Comcast wants.  Good luck.

The seller on ebay was us_auctions4u  They have the Tc8305C wireless router for sale also.  Just search 'battery for TC8305C on Ebay and this user should come up with the battery that you need.  It looks like the price is higher now than what I paid for it ($42..49) but they sitll offer free shipping.  Good luck.
