Same with "time" and distance when you put a battery in a clock---off of the shelf it starts ticking!
At some pt. our solar system was a million times bigger than it is now...the galaxies too...don't you think?
Earth was a vast spiralling cloud circling the sun...a solar furnace collecting--heating up---
over the distances we are just looking at the "stretch" traces---marks(not time)?
When did the clock--time start?
Relative to what do we know if matter-time is still shrinking if the rate--SIZE is constant---proportional?
Will we be condensed dust?
There are shifts and jumps we have no way of knowing of--- just thinking from our own time-space frame is ridiculous!
That depends on the battery type. The typical chemical-metal sandwich (voltaic pile) is charged when the ingredients are assembled. The current comes from the oxidation of the metal, not from a stored charge.
