First, let's get clear on what batteries are there. According to the substances and technology used to manufacture the battery, there are lead-acid batteries, lithium and lithium-ion batteries, nickel-cadmium batteries, and nickel-metal hydride batteries. Many other types of batteries, of course, but the ones above are very common and most widely used.

Cylindrical Lithium-ion batteries are very powerful. These batteries are used to power cars, computer terminals, forklifts, and other products that require high power. This battery is not suitable for smaller products because it is designed for high-power situations.
Since most of the batteries are assigned a specific letter accordingly, eg. two "A" batteries, the lead-acid battery is marked with the letter A. So if you see an article that requires Battery A, you know you need a lead-acid battery for this device to work.
There are currently two main types of battery A. This battery is useful, for example, when the power supply is turned off for various reasons. At this point, lead-acid batteries can be used in emergency lights to provide the required lighting.
Lithium and lithium-ion batteries are great instant power providers. A common use for lithium batteries is in consumer products such as portable radios. This battery is also used to drive hybrid electric cars and ordinary electric cars. Items that normally run on lithium-ion batteries include calculators, walking aids, radios, flashlights, and even sensor lights. While the battery sizes for these devices may vary, there are similarities. While you can purchase several different batteries for your different devices, it is more economical to purchase a fully rechargeable battery.
