The CR1220 battery is a miniature, tablet-shaped battery. Power supplies are used for various devices, including calculators, watches, scales, gadgets and any other small devices.
It differs in CR1220 in that it has a high degree of energy intensity. In addition, trusted manufacturers supply batteries of this type with a long service life of up to five years with continuous use.

Specifications CR1220
All CR1220 batteries are uniformly sized. The digital designation indicates that such models will fit equally well, regardless of manufacturer. The dimensions of the device are as follows:
- diameter - 12.5 mm;
- thickness - 2 millimeters.
These batteries are not batteries, although they perform the same functions. It is not possible to recharge the power source.
The main technical characteristics are approximately the same for all devices. The degree of energy intensity, the range of operating temperatures may slightly vary. Technical specifications:
- Output voltage - 3 Volts;
- The battery is lithium (cr stands for lithium class);
- Capacity - about 300 mAh;
- The degree of self-discharge is from 2 to 4 percent per year.
It is important to pay attention to the temperature range in which the battery will be used. For example, the Russian Federation is characterized by a strong variation in climatic conditions for various regions. If you are in the North, it would be best to buy a battery that works at temperatures up to -40 degrees than one that only works up to -30 degrees.
Battery Applications
The versatile and practical CR1220 batteries offer several advantages. This makes them an excellent option for installation in miniature devices that require constant charging. At the same time, models are convenient in that they have a long service life. If you install the power source on the calculator, then it does not discharge even with constant use for five years.
Main scopes:
- small computer equipment;
- medical devices;
- calculators and other devices for computing operations;
- small electronic devices;
- gadgets for electronic games and consoles;
- remote controls.
- watches, scales and children's toys.
CR1220 batteries are used in familiar devices that are used daily. Due to the demand for models, manufacturers are engaged in their development, so from year to year the cost decreases.
Battery analogs CR1220
The power source can be not only lithium, but also alkaline or zinc, it does not really matter.
Usually called as an analogue:
- SR1220.
- LR1220.
- DL1220.
- 5012LC.
The main criteria when choosing an analogue are size and voltage.
Can I charge the CR1220 battery
Due to the materials used, design features, the CR1220 battery cannot be charged. But this quality does not make the battery any worse.
Miniature power devices with a minimum degree of self-discharge are completely discharged with constant use of the device not earlier than after a few years. Taking into account the small price of the tablet, we can say that the inability to charge is not a problem.
Popular manufacturers and their features
A number of foreign and Russian companies are engaged in the production of such models. The range of prices is wide, in the markets and in online stores you can find options for 50 rubles, while others cost ten times more. The cost depends on what energy intensity, what material the battery is made of.If we are talking about tablets for cameras, then they are often supplied together with special battery holders, and this also incurs an additional price.
Optimal in terms of energy intensity, durability and cost are models by Varta or Renata. Good options at a low price provide Camelion.
Also pay attention to other companies:
- Duracell
- Energizer
- GP;
- Maxell
- Panasonic
- Trophy
- Sony
Separately, it is worth noting the manufacturer of Cosmos. Batteries of the Russian manufacturer are high-quality, energy-intensive, serve for a rather long time and at the same time have a minimal cost. You should not rush to conclusions, you can determine which is better after studying the technical features.
What to look for when purchasing
Product specifications can be found on the packaging for the power source. Pay attention to:
- manufacturing material (if the device is used in wet conditions, the material must necessarily be resistant to corrosion);
- rated capacity;
- output voltage;
- galvanic cell;
- new voltage energy (3v);
- temperature range of use.
Strong attention to the country of the manufacturer should not be paid. As practice shows, high-quality devices of both foreign and Russian companies.
