What is the voltage of the battery?

The lead-acid battery can be repeatedly charged and discharged, and its single cell voltage is 2V. A battery is a battery pack composed of one or more single cells, referred to as battery for short. The most common battery is 6V, and others are 2V, 4V, 8V and 24V batteries. For example, the battery used in the car (commonly known as battery) is a battery pack with six lead batteries connected in series into 12V.

For traditional dry-charged lead batteries (such as automobile dry-charged batteries, motorcycle dry-charged batteries, etc.). ), distilled water should be added after a period of use to keep the density of dilute sulfuric acid electrolyte at about 65438±0.28g/ml; For maintenance-free batteries, it is no longer necessary to add distilled water before the end of service life.

Extended data:

Chemical batteries can be divided into: primary batteries (primary batteries); Secondary battery (rechargeable battery); Lead-acid battery; Fuel cell.

Among them, primary batteries can be divided into paste zinc-manganese batteries, cardboard zinc-manganese batteries, alkaline zinc-manganese batteries, button zinc-silver batteries, button lithium-manganese batteries, button zinc-manganese batteries, zinc-air batteries and primary lithium-manganese batteries.

Secondary batteries can be divided into: nickel-cadmium batteries, nickel-hydrogen batteries, lithium-ion batteries, secondary alkaline zinc-manganese batteries and so on. Lead-acid batteries can be divided into: open lead-acid batteries, fully closed lead-acid batteries and so on. Fuel cells can be divided into: hydrogen-oxygen fuel cells, methanol-air fuel cells and so on.
