SO, I THINK YOUR INPUT IS VALID, MAYBE YOU CAN HELP IMPROVE THIS ARTICLE.
LIKE WHEN I WENT HERE TO THIS PAGE YEARS AGO, I WAS BUMMED, THAT I MIGHT
HAVE TO BUY A NEW BATTERY, BUT WAS HAPPY THEY DID NOT SEEM TO COST VARY
MUCH, AND THERE WAS PLACES YOU COULD GET THEM FROM. I HAVE NOT HAD TO BUY
ANY BATTERIES, BECAUSE, I WAS ABLE TO FOLLOW THE TROUBLESHOOTING GUIDES AND
FIX MY XO-1'S MYSELF.

AND DEVELOPERS, SORRY IF THIS IS NOT THE RIGHT PLACE, STYLE, AND/OR WAY TO

HOPE THAT HELPS PETER E.
