Thought I had found the answer a week ago why my new E10 was not
charging and a group member indicated that I had to press the charge
on/off button but it was still not charging after 24+ hours!

I sent an email to Eton support explaining my issue. They replied that
they had a batch of bad rechargeable batteries where the + side was
incorrect in sizing and would not charge?? The bottom line is they are
sending out new batteries no questions asked! That's great service!

If you have a Eton E10 and not tried re-charging your batteries
you might want to check it out and be sure they are working correctly.
