Specification: Model:ER3V/3.6V Battery Voltage: 3.6v Capacity: 1000mAh Size: 25x14.5mm Weight:15g Applications: It is used for storing data of various Omron meters, water meters, gas meters, automatic sanitary wares, PLC machine backup power supplies, CNC machine tools and automation equipment. Feature: 1. Lithium-thionyl chloride battery is the most energy-efficient battery in actual use. 2. When the current current density is discharged at normal temperature, the discharge curve is extremely flat. The working platform remains unchanged in the 90% capacity range; 3. The battery can work normally in the range of -40 ° C ~ +85 ° C. The capacity at -40 ° C is about 50% of the normal temperature capacity, showing extremely excellent high and low temperature performance; 4. Annual self-discharge rate Less than or equal 1%; storage life of more than 10 years
