They are produced by Lithium Element
At the «Lithium-Element» (part of Rostec) have mastered the production of ER 34580 power supplies for operation under extreme load conditions (up to 150 g). The battery has a capacity of 14 A•h, a voltage of 3.6 V and a service life of at least three years. The operating temperature range is from -30 to +60 °C.
«Current sources of the electrochemical lithium-thionyl chloride system are primary sources of constant-ready current and are intended for power supply of security systems, alarm systems, gas, heat, water meters, cash registers, electrical measuring instruments, stationary and mobile communications, as well as for autonomous (emergency) power supply to automation and communication facilities in case of disruption of standard power supply systems. The current sources are sealed, do not emit gases or electrolyte, operate in any spatial position, allow the possibility of series-parallel connection into batteries to provide the required voltages and capacities», — writes the editor-in-chief of the magazine «Behind the Wheel» Maxim Kadakov.
Production of the ER 34580 has been mastered under the import substitution program, but it is not yet clear whether all the components in this battery are Russian.
You are, of course, familiar with the format – like the old Soviet «elements 373»: height 61.5 mm, diameter 34 mm. Only Soviet household batteries in the carbon-zinc version had an output of 1.5 V. But the standard size itself (Element D) is not Soviet: this form of batteries was proposed back in 1898 by the company that we now know as Energizer.
