Batteries (type AG10) are necessary part of our books.

Batteries must be replaced when the music stops completely or in the middle of the songs.

​Be aware that most AG10 batteries on the market are weak/expired and do not work properly with our books. We do NOT recommend Maxell batteries.

WE HIGHLY RECOMMEND TO BUY SPARE BATTERIES - THESE BATTERIES HAVE BEEN TESTED AND WORK PERFECTLY WITH OUR MUSICAL BOOKS
