batteries used in tractors, trucks, inverters are also made of cells then why it is called a battery ?
Hello,
Cell is the smallest unit of a battery. Which means a single cell can make a battery, two or more cells together also can make a battery. A battery is actually a power supply with more than one cell. This is why, the DC power supply used in tractors, trucks, inverters etc are called battery (one such battery contain about 4-6 cells).
