Took my remote apart this afternoon. The battery is a Renata(Brand) The numbers on the battery are CR2450N 3 Volt Lithium. I bought straight 2450 from wally world and don't think they will work as stated in above post. Bought the correct ones at BatteriesAndButter.com Batteries-Duracell Alkaline, Eveready Energizer, Rechargeable Ni-MH, CD's, DVD's, iPod Accessories, & Blank Tapes. Thanks for the heads up as I would not have had the right replacement for remote.
