I have two clock/radio television units. Both have battery backups.
I installed fresh 9 volt batteries and when power was restored last
night after a 3 hour outage, the clocks were 8-10 minutes fast. What

Just curious.


I've noticed the same thing, chalked it up to it not having very good
freq control when on batteries.
