CR2012 Battery Specifications
In its form, the battery resembles a tablet, that is, its diameter is much longer. The main characteristics can be found in the marking itself. CR - means that it is a lithium battery, and in 2012, that the diameter is 20 mm and the height is 1.2 mm. This makes it the best option for use in most household items.
Battery Parameters 2012:
- form - cylinder;
- discharge current - 0.1 mA;
- diameter - 20 millimeters;
- height - 1.2 mm;
- capacity - 55 mAh;
- power - 3v.
The battery has a low degree of self-discharge. On average, this is 2 percent for a year of intensive use. The optimal range of operating temperatures is from -25 degrees to +35 degrees. At lower temperatures, a loss of energy intensity is observed, and at higher temperatures a loss of charge. This type of power supply can be used for about five years under the conditions. Batteries are protected by a special compound on top from fire and corrosion.

Battery Applications
2012 batteries are used to power many types of household appliances. Most often they can be found in:
- hours;
- trinkets;
- photographic equipment;
- computer equipment;
- engineering tool;
- medical equipment.
The battery is used to power small devices with small overall dimensions, which require a small but constant energy for a long time.
Battery Analogs CR2012
Batteries with the marking CR2012 and the designation 2012 are full analogues not only in their standard sizes, but also in general technical characteristics.
You can replace it with an analog in any device, since they have the same dimensions. Marking 2012 means that the diameter of the battery is 20 mm, the thickness is 1.2 mm. This means that you can freely use power supplies with the same designation.
Can I charge the CR2012 battery
It is not possible to charge the battery. But in fact, this is not a significant problem, since the power source has a long service life and low cost.
Only batteries of this type can be charged. They are also represented by various manufacturers, but not in such a large quantity as batteries.
Popular manufacturers and their features
The highest quality batteries of 2012 are supplied by Renata, Panasonic and Energizer. The products are certified, on the Internet you can find many reviews about these models. They differ in such characteristics:
- full compliance with state standards;
- security;
- high temperature range;
- long service life.
It is not difficult to pick up a battery, since when marking 2012 with 3 Volts, the dimensions will be identical.It is not recommended to buy power supplies from unverified manufacturers, as they can have a high degree of self-discharge.
What to look for when purchasing
When buying in online and offline stores, attention should be paid to the conformity of technical characteristics and features of use.
It is necessary to consider:
- sizes
- capacity;
- voltage;
- security;
- life time;
- production date;
- degree of self-discharge;
- working temperatures.
A galvanic cell is used in many household and specialized appliances. There will be no problems with his choice, since such models are produced by many companies.
