Tekcell Lithium batteries
Tekcell lithium batteries (manufactured by Vitzrocell, South Korea) are current sources designed for professional and household use. The Tekcell brand is widely known in the battery market due to its flexible pricing policy and high quality products.
The assortment of our company includes:
Lithium-thionyl chloride SB series current sources
The bobbintype batteries are designed to operate in low-current mode and are focused on the backup power supply of storage devices. Operating temperature from -55 to 85°C. The negative electrode is made by lithium deposition on the inner surface of the housing. Most of the volume of the battery case is occupied by a porous cathode. The batteries are designed to power the devices with a small current for a long time.
Technical characteristics of SB series batteries
- High and stable operating voltage
- Low self-discharge rate (less than 1% per year at a storage temperature of 20°C)
- Operating temperature -55°C...+85°C
- Non-flammable inorganic electrolyte
- Bobbin type ("coil" type)
- Sealed metal-glass structure for leak-free operation

Lithium dioxide manganese current sources of the CR series
Batteries with a spiral type of electrode (spiral type) provide a high and stable operating voltage, are durable and safe, have a low self-discharge (less than 2% per year), remain operational for up to ten years, give out a large current (800...3500 mA) and have a significant capacity (850...2400 mAh). The battery housing is made of stainless steel, the membrane separating the electrodes is made of polypropylene.
To protect against overheating and short circuit, a thermistor with a positive temperature characteristic is present in the battery design. When heated, its resistance increases slightly, but when it reaches +85°C, the resistance increases sharply, which leads to a decrease in the current through the battery to a minimum value.
Tekcell lithium-dioxide manganese batteries are used to power backup storage devices, clocks, calendars, water meters, gas meters, automotive electronics.
