What is the voltage of a dry battery? Dry battery voltage classification. With the development of science and technology, dry batteries have become a large family, with over 100 types so far. Dry batteries belong to the primary batteries in chemical power sources and are a type of disposable battery. Because the electrolyte of this chemical power supply device is a non flowing paste, it is called a dry battery. What is the voltage of a dry battery? The editor will answer.

A dry battery is a type of photovoltaic battery that uses a certain absorbent (such as wood chips or gelatin) to make the contents into a paste that will not overflow. Commonly used as a power source for flashlights, radios, etc. Dry battery is a type of chemical battery that generates direct current using a paste like electrolyte (wet battery is a chemical battery that uses liquid electrolyte). It can be roughly divided into two types: primary battery and secondary battery. It is a commonly used and lightweight battery in daily life. They can be used on many electrical appliances.

Dry battery belongs to the primary battery in chemical power sources, which is a disposable battery. It uses manganese dioxide as the positive electrode and zinc cylinder as the negative electrode to convert chemical energy into electrical energy for external circuits. In chemical reactions, due to the higher reactivity of zinc compared to manganese, zinc loses electrons and is oxidized, while manganese gains electrons and is reduced.

What is the voltage of a dry battery?

The nominal voltage of ordinary manganese zinc batteries (also known as carbon batteries) is 1.5V, and the new battery will be higher, up to 1.55-1.6V. The voltage of each dry battery cell is 1.5 volts. If three cells are connected in series, it is 4.5 volts. If three cells are connected in parallel, it is still 1.5 volts.

1. Generally speaking, the voltage of a regular dry battery is usually 1.5V, which meets the standard voltage standards for dry batteries. However, in special circumstances, the voltage of cadmium nickel material dry batteries and dry batteries that can be recharged with nickel hydrogen is 1.2v.

2. Another type is cylindrical dry batteries, which are made using lithium atoms and have a voltage of 3.7V. Another type is dry batteries made from lead batteries, which have a voltage of 2v.

3. Recently, Europe has launched a rechargeable dry battery, which uses zinc charging and has a voltage of 1.9V.

4. We usually use almost all DC batteries, and DC batteries are the ones we use more frequently. It uses a DC voltage of 1.5V. Although this type of battery is written as 1.5V, in reality, its voltage is slightly higher than 1.5V. There are still many batteries on the market, and the voltage of batteries made of different materials is different, but there will not be too much deviation. The voltage of dry batteries is not allowed to be too high, because dry batteries can directly come into contact with human skin, and high voltage can easily lead to safety accidents such as leakage.

Classification of voltage for dry batteries

With the development of science and technology, dry batteries have become a large family, with over 100 types so far. The voltage unit of a dry battery is expressed in V (volts). The voltage value of a dry battery varies in different states, and the nominal voltage is the core parameter of the voltage of a dry battery.

In practical applications, there are two types of dry batteries: carbon batteries and alkaline batteries. Although the reaction mechanism is different, the voltage of a lithium battery is the same among them. The nominal voltage, also known as the rated voltage, is one of the fundamental indicators that distinguishes a dry battery from other batteries. The nominal voltage of a dry battery is 1.5V, which refers to the potential difference caused by a chemical reaction of the positive electrode material of the battery. In this sense, people refer to a dry battery as a 1.5V battery based on the voltage of a dry battery.

However, the voltage of a dry battery is not always at 1.5V, otherwise, a dry battery can be used up endlessly. In fact, during the operation of a dry battery, the voltage of the battery goes through the stages of open circuit voltage, working voltage, and termination voltage in sequence.

The voltage of a dry battery exhibits different values in different states, and the voltage of carbon batteries and alkaline batteries also varies due to different materials. The voltage of the same dry battery is much more stable in alkaline batteries than in carbon batteries. In practical applications, alkaline batteries have a longer lifespan and are much more stable.

1. Ordinary batteries

A regular battery is a zinc manganese battery, with a voltage of 1.5V per battery. There are three main types of ordinary batteries: ① Normal mode, labeled as Wei 6 or R6S; ② High capacity battery, labeled as R6C; ③ Zinc chloride high-power type, marked as R6P. The advantage of R6P is its large capacity, which is close to alkaline batteries. There are small groups AM3/UM3, which are called alkaline and carbonaceous

2. Alkaline batteries

The alkaline battery model is LR6, and the voltage of a single battery is 1.5V. Its characteristic is its large capacity, generally 2-6 times that of ordinary batteries, and it can discharge large currents. Suitable for electrical devices that require high current, such as tape recorders and flash lights.

3. Rechargeable battery

The voltage of a single battery is 1.1 or 1.2V. Nickel cadmium batteries labeled with NICKEL-CADMlIUM, and nickel hydrogen batteries labeled with NICKELMETALHYDRIDE (or NI-MH). The charging and discharging cycle of the rechargeable battery can reach 500-1500 times, and it can discharge with high current. The internal resistance does not change much at the moment of discharge, but only increases sharply at the end of discharge. Among them, nickel hydrogen batteries have no memory, and currently have a maximum capacity of 2700mAh, making them more excellent than nickel cadmium batteries. Their economic efficiency and excellent environmental performance will gradually replace alkaline batteries and nickel cadmium batteries.

Dry battery voltage is divided into three types: standard voltage, open circuit voltage, and working voltage. The voltage of the dry battery involved in the working state includes standard voltage and working voltage. When it is not in the working state, the voltage of the dry battery is in the open circuit voltage and termination voltage, because the chemical reaction of the dry battery is irreversible. Therefore, when the voltage of the dry battery is at the termination voltage, it means that the battery will be scrapped.
