A battery is a group of cell to increase current or voltage or both.
This site is the best known source for questions like these -----> http://www.google.com
I hope you will not get offended.

A cell is the basic unit of an electrochemical generator. The cylinders you put into portable devices and have 1.5 V are one example.
A battery is a group of cells in one package. The small rectngular 9 V power source with snap connectors for portable devices are an example.
Battery in general definition is a group of things. There can be a battery of tests. A group of military canons is called a battery.

Is it safe to put batteries of the same voltage, but different capacities in parallel?
My scenario: I have an old UPS with a 7AH battery, I would like to increase capacity. Should I just buy a larger battery, or could I hook another battery in parallel of same voltage rating but different capacity?

| If both batteries are fully charged you can parallel them. After that they will discharge and charge by sharing the current each way.

At school we always used to refer to cells as single cells, explains itself .
Think of your car battery 12volts 6 cells.

Galvanic cell: A device that is capable of spontaneously tansforming chemical energy into electic energy. Examples are flashlight batteries and fuel cells.
Batteries: A galvanic cell; or a group of galvanic cells connected in seies, in paallel, or in a seies-parallel combination fo the purpose of increasing their voltage or current capability.

parelleling batteries is not good idea. they should be pure identical. and it is impossible. i recomment you to use 12a battery.............not much than this.
because your charge circuit may be harm....

The charging circuit isn't all that suffisticated(?), it just puts out 13.8v to the battery, but with no battery attached it puts out 19v.
