Many modern electrical devices are battery powered. Used power supplies vary in size, shape, capacity and technology. Therefore, when replacing a used battery, it is important to know and understand all the characteristics of the battery so that the new element does not harm the device.

J Battery Specifications
This galvanic cell is made in the case in the form of a rectangular parallelepiped with a cut corner to the right. Both electrical contacts are placed by the manufacturer in the upper part of the product (“-” on the upper edge, “+” on the trimmed corner). This solution eliminates confusion with the polarity of the contacts when replacing the power source.
Due to the electrochemical properties of the substance ZnMnO2 (a compound of manganese oxide with zinc), battery J is an alkaline type. The product has a long shelf life in working condition, since the level of self-discharge is less than 1% per year. The main characteristics of J - batteries are as follows:
- Capacity 550-625 mAh (depending on model and manufacturer);
- Rated voltage 6 Volts;
- Temperature condition from -10 to + 50 ° С;
- Shelf life up to 7 years;
- Dimensions (HxWxD) 48.5 × 35.6 × 9.12 mm;
- Weight 340 grams.
J - batteries are delivered to the stores individually (1 package / 1 pc.) In a combination container: cardboard backing and plastic on top.
Battery Applications
The size of the considered power source is indicated according to the international marking system with 4LR61 symbols. The product is intended for use in devices with a high level of energy consumption. The battery is convenient to use, just inserted. Manufacturers used in the following types of equipment:
- Glucometers, tonometers and other types of medical devices;
- Devices made in a flat case;
- Photographic equipment;
- Battery-powered field TVs and radios;
- Alarm radio devices;
- Radio-controlled models of toys for children.
Battery Analogs J
In addition to the international marking (IEC), which determines the size of products, there are other classification systems, such as ANSI, NEDA and others. Analogs of J - batteries are power supplies marked as:
- 1412A;
- 1412AP;
- 7K67;
- 7K674;
- 4LR61.
In terms of dimensions, voltage and power, alternative analogs are practically not inferior to original products. Therefore, it makes no sense to spend efforts on the search for the original battery in order to replace the spent consumable.
Can I charge the battery
Alkaline batteries that have exhausted the manufacturer's specified life cannot be recharged. Discharged J-type consumables must be disposed of. To do this, it must be taken to a specialized collection point for used batteries. It is forbidden to throw in a regular trash can.
Popular manufacturers and their features
On sale there are products of the following brands: GP, Vatra, Duracell, Ceba, Panasonic, Energizer, Era and others. The main battery manufacturers of these brands are located in China, Russia, Hong Kong, the USA, Japan and Malaysia.
The more the brand is promoted, the more expensive its original products cost the buyer. Prices for J - batteries of different capacities range from 100 to 300 rubles
What to look for when purchasing
When choosing a replacement battery, you should pay attention to the characteristics that are important in operation. The battery should be suitable for the size and location of the contacts. Also important are the parameters for the rated voltage, capacitance, expiration date and power.
