Coin cell size, coin cell model comparison table

There are many kinds of button batteries, mainly depending on the number on the battery, such as CR2032, 20 is the diameter, 20mm, 32 is thick, that's it, generally CR1220, CR1616, CR1620, CR1632, CR2016, CR2025, CR2032, CR2430, CR2450, LR44, LR54, etc.

Common button batteries are as follows: carbon, alkaline, zinc-silver oxide, zinc-air, lithium-manganese dioxide, nickel-cadmium rechargeable coin battery, nickel-metal hydride rechargeable coin battery, etc. According to the shape, there is a distinction between monomer and cascading.

In detail, carbon button batteries are the most common and cheapest, and alkaline ones are a little more expensive, but they have a good discharge effect. Both voltages are, from alkaline AG1 to AG13, with nominal capacities ranging from approximately 15mAh to 140mAh. It is suitable for microampere discharge requirements.

It is mostly used in calculators, electronic toys, hearing aids, lighters, watches, etc.

Zinc-silver oxide button battery is the best among button batteries. Voltage, the capacity is higher than that of carbon, alkaline button batteries, the high-order discharge curve is stable, about 90% of the part is always stable above, the discharge curve is almost a straight line, and then quickly loses power, and the voltage falls vertically. The main uses are:

Calculators, hearing aids, cameras, watches, etc. In particular, the anti-leakage effect of this battery is particularly good, and the long-term use effect is also good, I once replaced two domestic Dali AG13 batteries that were placed in the SLR camera to power the metering system, and it took more than 8 years to replace the new product, and there is no sign of leakage at all. That's amazing!

In addition to being able to be powered by a single battery, due to its small size, high-volt batteries have also been developed - that is, multiple button batteries are stacked, and the common typical models are:

6F22 (9V), 4F22 (6V), 15F20 (, 10A (9V), 11A (6V), 23A (12V), 25A (9V), 26A (6V), 27A (12), 476A (6V), 120H7D (, 2X625A (3V) and many more. Due to the use of button batteries, the combined battery pack is very small, but the discharge intensity is not large, and it is mostly used in small motors and DC power supplies for small radio transmission. It should be noted that since high-volt laminated batteries are mostly produced by ordinary carbon battery combinations, they are generally not easy to store for a long time, so you should pay attention to the production date when purchasing, and try to use products produced within one year.

Due to the low cost, button batteries usually contain harmful substances, which are quite harmful to the environment.

Coin cell batteries. The model comparison table is as follows:

The more common button batteries are AG3, AG10, AG13 batteries used for toys and gifts, and computer motherboards.

The battery model on the computer is CR2032, which is used for CR2025 in the electronic dictionary, and is used for CR2016 or SR44, SR626 and so on on the electronic meter.

Summary. Dear, hello, button batteries, also known as button batteries, button batteries, flat batteries, etc., are commonly found in portable electronic devices such as calculators, watches, electronic small toys, and small **** devices. At present, the common types and sizes of coin cell batteries on the market are mainly as follows:

CR2016: diameter 20 mm, thickness mm. cr2025：

The diameter is 20 mm, the thickness is mm. CR2032: diameter 20 mm, thickness mm.

LR41: Diameter in millimeters, thickness in millimeters. lr44：

The diameter is millimeters, and the thickness is millimeters. These types of coin cell batteries are more common in the market, among which CR2016, CR2025, and CR2032 are more commonly used. When purchasing a coin cell battery, you need to choose the right model and size according to the needs and specifications of the equipment, and you also need to pay attention to factors such as the quality and brand of the battery to ensure the safety and service life of the battery.

Hope mine can help you! <>

Dear, hello, the new high state bright button battery, also known as button battery, button battery, flat battery, etc., is commonly found in calculators, watches, electronic toys, small **** devices and other portable electronic devices. At present, the common types and sizes of button batteries on the market are mainly as follows: CR2016:

The diameter is 20 mm, the thickness is mm. CR2025: 20 mm in diameter and as thick as a meter.

CR2032: diameter 20 mm, thickness mm. lr41：

The diameter is millimeters, and the thickness is millimeters. LR44: Diameter in millimeters, thickness in millimeters.

These types of coin cell batteries are more common in the market, among which CR2016, CR2025, and CR2032 are more commonly used. When purchasing a button battery, you need to choose the appropriate model and size according to the needs and specifications of the equipment, and at the same time, Qi Kuan needs to pay attention to factors such as the quality and brand of the battery to ensure the safety and service life of the battery. Hope mine can help you!

Dear, do you still have any problems that you don't understand and need to solve for you!

The comparison table of coin cell battery models is as follows:

The more common button batteries are AG3, AG10, and AG13 batteries for toys and gifts, and the battery model on the computer motherboard is CR2032, which is used for CR2025 in electronic dictionaries, and CR2016 or SR44 and SR626 on electronic watches.
