I replaced batteries in a Braille Lite and a TNS and the total including tax at Batteries Plus was $57.00 If anyone wants to ship their notetakers to a Batteries Plus that has already changed out these batteries the store that I got my batteries from will replace and install them if shipped to them. I have already talked to the store manager about this and he'll be happy to help. If anyone would like contact information, write and I'll be glad to send the info. And, we do get a 1 year warrantee on our replaced or rebuilt batteries from Batteries Plus. Donna
