True. A battery is typically composed of multiple electrochemical cells stacked together, which work in tandem to provide a higher voltage and greater energy capacity. Each cell contains an electrolyte and electrodes, facilitating the chemical reactions that generate electrical energy. Thus, batteries can be seen as a collection of these individual cells.
Lots of things have an electrochemical cell in them. That electrochemical cell is a battery. You cell phone has at least two of them. There is a small one that "keeps alive" memory if you remove the primary battery. A flashlight has a cell or cells in it. We could go on all day. Motor vehicles have a battery, which is a collection of electrochemical cells. Note that a battery could be composed of a single cell, like the "AAA", "AA", "C" and "D" cells. We call them batteries, but they are a single electrochemical cell. A 9-volt battery, on the other hand, has several cells in it stacked in series so their voltages add. That car battery we mentioned is 6 electrochemical cells "long" so that the voltages will sum to the 12 volts (which is actually a bit over 13 volts).
A battery is very simple. A single cell is made of two dissimilar metals in an acid. When several cells are stacked together we get batteries with different power outputs.
A combination of two or more electrochemical cells in a series is called a battery. By connecting the cells together in series, the voltage of each cell is added together to create a higher total voltage output.

Yes they do
A battery, in common terms, refers to a device that stores and provides electrical energy through electrochemical reactions. It consists of one or more electrochemical cells that convert stored chemical energy into electrical energy. Additionally, in a broader context, the term "battery" can also refer to a collection of similar items or components grouped together, such as a battery of tests or instruments.
