Direct No. 2 Say so much and don't be afraid of trouble.

LR6 is the model specified by the International Standards Organization IEC for alkaline zinc-manganese batteries, and the UM3 type is the model of Tachibana Wei specified by Japan for ordinary zinc-manganese batteries.

No. 7 battery. The battery is the only number that can be taken out to see for yourself, the battery commonly used in life, the small battery has the No. 7 logo on the package, and the battery shows the No. 5 battery on the package.

The large battery can be directly seen as No. 1 on the package, and the number of batteries can also be confirmed according to the size of the battery.

The performance parameters of the battery are mainly electromotive force.

Capacitance, specific energy, and resistance. Using the battery as energy, you can get a current with stable voltage, stable current, long-term stable power supply, and little influence from the outside world, and the battery structure is simple, easy to carry, simple and easy to operate, not affected by the climate and temperature of the outer Douchangjie, and the performance is stable and reliable.

, AAA isNo. 7 battery.

The relevance is as follows. The model of the electric delay pool.

It is generally divided into No. 5 and No. 7, which are particularly commonly used, and the so-called key stuffy AA battery is No. 5 battery.

And AAA batteries.

It's battery No. 7! AA and AAA both indicate the battery model.

For example, AA is what we usually call a No. 5 battery, with a general size of 14mm in diameter and 49mm in height; AAA is what we usually call a No. 7 battery, and the general size is: diameter 11mm, height 44mm.

For other models, let's talk about the common "aaaa, aaa, aa, code bright key a, sc, c, d, n, f" these models. AAAA models are rare, disposable AAAA Energizer alkaline batteries.

It can also be seen occasionally, and it is usually used in a computer pen. Standard AAAA (flat head) battery height, diameter.

AAA type batteries are more common, and the general ones are AAA batteries, standard AAA (flat head) battery height and diameter.

UM3 is a No. 5 battery. No. 5 battery is one of the types of batteries, its general size is 14mm in diameter, and the height number of reed batteries is widely used in many small electrical appliances and digital products because of its small size and moderate capacity.

A battery is a device that converts chemical energy into electrical energy in a cup, trough or other container or composite container that contains an electrolyte solution and metal electrodes to generate an electric current. It has a positive electrode and a negative electrode. With the advancement of science and technology, batteries generally refer to small devices that can generate electrical energy, such as solar cells.

The performance parameters of the battery mainly include electromotive force, capacity, specific energy and resistance. The use of battery as energy, can not be as good as to get a stable voltage, stable current, long-term stable power supply, very little influence by the outside of the current, and the battery structure is simple, easy to carry, easy to charge and discharge operation, not affected by the external climate and temperature, stable and reliable performance, in all aspects of modern social life plays a great role.

UM3 is a manufacturer specification for Hongyu potato rechargeable batteries.

1. Ordinary dry batteries are wide.

Ordinary dry batteries are zinc-manganese batteries, and the voltage of each battery is. There are three main types of ordinary batteries: normal mode, the symbol model is Wei 6 or R6S; High-capacity battery, marked model R6C; Zinc chloride.

The advantage of the high-power type, the logo model is that it has a large capacity, close to alkaline batteries.

There are small groups of am3 um3 which are the names of alkaline and carbonaceous

2. Alkaline dry battery.

The symbol model of the alkaline shield cell is LR6, and the voltage of a single battery is. It is characterized by a large capacity, generally 2 6 times that of ordinary batteries, and can be discharged with a large current. It is suitable for use in electrical devices that require high current, such as cassette recorders and flashes.

1) Select the battery according to your need. For example, for flashes, cameras, MP4s, electric toys and other appliances that require high current output, it is best to use alkaline zinc-manganese batteries (L).

For remote controls, clocks and other appliances with general electricity needs, ordinary zinc-manganese batteries (S, C, P) can be used.

2) Pay attention to the battery's performance** ratio.

Don't blindly believe in foreign brands. In fact, the performance ratio of many domestic brand-name batteries is higher than that of similar foreign products.

3) Pay attention to the storage period of the battery. Shelf life of ordinary zinc-manganese batteries.

for 2 years. New products should be selected at the time of purchase. The difference between alkaline zinc-manganese battery and ordinary zinc-manganese battery There are two types of batteries: alkaline and ordinary zinc-manganese batteries in the eyes of ordinary people.

4) The alkaline zinc-manganese battery used the flash 144 times, the camera film was 8 rolls, and the toy was turned on for 183 minutes. These indices are on average better than ordinary zinc-manganese batteries in use during the same period81 times, and the performance ** ratio is also better

41 times. For consumers, the use of alkaline zinc-manganese batteries can be used reasonably and safely.

What is the battery.

You're so close <>

What is the battery No. 1, No. 5, No. 7 is the battery. The performance parameters of the battery mainly include electromotive force, capacity, specific energy and resistance. Dry batteries are also called manganese-zinc batteries, and the so-called dry batteries are relative to voltaic batteries, and the so-called manganese-zinc refers to its raw materials.

For dry batteries of other materials such as silver oxide batteries, nickel-cadmium batteries. The voltage of a manganese-zinc battery is. Dry batteries consume chemical raw materials to produce electricity.
