HP R817 CAMERA & HP SCANNER

I NEED TO REPLACE THE BATTERY FOR A R817 CAMERA--AND THE POWER CORD FOR THE

HP SCANNER. WELL TO MY SHOCK NEITHER ARE AVAILABLE OR IN STOCK BOTH IN USA OR CANADA. WHAT IS SO HARD ABOUT REPLACING A BATTERY?? PRESENTLY I AM SO FRUSTRATED WITH HP PRODUCTS. THEY FORCE YOU AS A CONSUMER TO HAVE TO GO OUT AND BUY NEW PRODUCTS. TRUST ME IT WILL NEVER BE AN HP PRODUCT AGAIN !! I WILL DO WITHOUT EVEN IF THEY WERE THE ONLY PRODUCT ON THE SHELF.
