CR2032 Battery

The work of many miniature gadgets depends on the electric current, but you can not install ordinary finger batteries in such devices. To provide wrist watches, alarm key rings or children's toys with constant low-voltage electricity, in this case, lithium “tablets” with conclusions located on a rounded surface are most suitable.

If it is necessary to replace the battery, it is necessary to purchase the same battery model or select an analog that will be suitable not only for current and voltage, but also for size. This article will describe the main technical characteristics of the CR2032 battery, consider the difference between the elements of the most well-known companies, and give full analogues of this product.

Specifications CR2032

The rounded shape is the main difference between this galvanic cell and finger batteries.

In addition to appearance, this battery has the following features:

• The type of electrolyte is lithium and manganese.
• Voltage - 3 v.
• Diameter - 20 mm;
• Height - 3.2 mm.

For accurate identification, the CR2032 is standardized, therefore, regardless of the manufacturer, the battery will always have a class of 2032 (according to the IEC standard).

Battery Application

Most often, this battery can be found in the following instruments and devices:

• In the motherboard to provide backup electricity to the bios of a computer or laptop.
• In hours.
• In the toys.
• In remote control panels.
• In apartment calls.

In addition, the CR2032 battery can be used as the main battery for floor scales and powerful laser pointers.

Battery analogs CR2032

If for some reason it was not possible to purchase the original battery, then it can be replaced with the following analogues:

1. DL2032.
2. BR2032.
3. EBR2032.
4. DL2032.
5. 5004LC.
6. SB-T15.
7. Two batteries CR2016.

Any of the listed elements will allow replacing the CR2032 both in voltage and ideally "lie" in the device’s seat.

Can I charge the cr2032 battery

It is not a battery, so using a charger to restore the battery capacity will not work. In addition, such actions may result in a fire or depressurization of the battery as a result of an explosion.

You can for some time try to restore the charge with various "folk" methods, but it will not last long. Given the low cost of the product, it is recommended to purchase a new CR2032 or one of its analogues, what to do with such a risky event.

Popular manufacturers and their features

CR2032 lithium battery is manufactured by many companies. The most popular among them are:

1. Сamelion. A well-known manufacturer of electrical goods have good resistance to self-discharge, which allows for many years not to change the battery in devices that are rarely used.
2. Duracell. The batteries of this company have a very high endurance, and even in devices that consume relatively much electricity, they significantly exceed their analogues.
3. Energizer The peculiarity of this manufacturer is that the voltage of the new 3 volt battery lasts a long time, even in everyday use.Due to such qualities, it is recommended to use the battery as a source of electricity for the BIOS of a computer.
4. Panasonic The battery from a well-known brand is primarily intended for use in devices with low power consumption. Ideal for watches, door locks and alarm key fobs.
5. Sony One of the world leaders among tablet manufacturers. It features high capacity and resistance to adverse operating conditions.

In addition to these brands, you can buy a good battery under the brands: GP, Maxell, Renata, Varta, Philips. Which battery is better to understand can only be experienced by installing a battery in the device.

What to look for when purchasing

When choosing a disk-type battery, pay attention to the following parameters:

• Size - 20 by 3.2 mm.
• Voltage - 3 Volts.
• Capacity - ~ 210 mAh.
• Fresh release date.
• Sealed packaging.
• Lowest discharge current.

First of all, attention is paid to the size, otherwise the element will not install correctly in the battery holder. The magnitude of the voltage is also very important, because if this value is exceeded, the electrical device may fail.

The higher the battery capacity, the longer it will work, therefore, despite the high cost of products with a large value of this parameter, it’s worth buying a battery once to forget about the need to replace it for a long time.
