Two or more cells that are electrically connected together and fitted with devices necessary for use describe which term?

• A. Battery
• B. Battery cell
• C. Lithium Battery
• D. Lithium Ion Batteries

Answer: (A)

When two or more cells are connected together and packaged with the terminals and any necessary safety or control devices, that assembled unit is called a battery. A single cell is just one energy-converting unit and doesn’t include the full assembly you’d need for practical use. Terms like “lithium battery” or “lithium ion batteries” refer to chemistry and can describe either a single cell or a multi-cell pack, but the description here emphasizes the assembled power source, which is a battery.
