Can I use a charge controller that is 12 V and 7 A-H on a 12 V and 1.2
A-H battery?

Also, using the same controller 12 V and 7 A-H, do I have to buy a new
controller to charge a 12 V 24 A battery?  If I do need to buy a new
controller, which I probably will have to, what is the point of a
controller that is limited to 7 A-H at 12 V if the battery has very
low amp-hours?

If I have a 12 V and 7 A controller, can I charge two batteries that
are 12 V and 7 A each?
