I am just back from a weeklong journey that included a four day camp
on the same spot. During those four days, the lighting, fridge fan,
exhaust fan, stereo and other things took their toll and on day three
the battery got so low that they clock stopped. I pulled out my "smart
charger" and it kept clicking back to "check" instead of charging the
battery. An electrician camped next door loaned me his analog charger
and said that when those digital chargers don't sense any current
coming from the battery, they can't charge it.

Any truth to that? If it is true I have found another item bound for
the trash can.
