how does charging batteries work

Suppose you have multiple usb ports in a bus. You must connect them parallel, so that if one fails the other will work.
So the voltage on all the ports is the same, but the current will be lower.
Is a battery charges like a capacitor? The higher the current the faster it charges?
Why is there optimal voltage on batteries?
It has been a while since i studied physics in school so please explain this to me

batteries. are. not. capacitors.

they use chemical process.

batteries have a resistance and are a voltage source.

plz google basic electronics

I said similar to capacitor in the sense that the higher the current the faster it charges.
Maybe i didn't explain it clearly enough but still...

>The higher the current the faster it charges?
Yes.
But since it has an internal resistance you can't just go and pump the largest amount of current you can without any concern or you will run into overheating issues.

>Why is there optimal voltage on batteries?
What do you mean?

Hmm, i see written on batteries some current and voltage. I guess that its the sort of best current and voltage to charge it with.
I see.
Thanks!
