ER346 15 is a type of capacity battery, sometimes written as ER346 15H, which is generally omitted, and is also called D-type battery. The battery is a carbon-coated cylindrical battery, suitable for medium and low discharge, and the discharge rate shall not be higher than C/ 100 (C refers to the capacity of the battery, for example, the nominal capacity of the battery is 19Ah, and 1C is 19Ah). This kind of battery has high specific energy. For example, the D-type battery ER346 15 can release the capacity of 19.0Ah at 3.5V, while the traditional alkaline zinc/manganese dioxide battery can only release the capacity of 15Ah at1.5V. The structure and performance of the battery have been introduced in detail in the lithium thionyl chloride battery for reference. Here, its main performance is explained. The battery is sealed in stainless steel shell, and its working temperature is -55℃ to 85℃, voltage range is 2.0 to 3.6V, rated capacity is 19Ah, and it is discharged to 2.0V at 20℃. This kind of battery is placed in different directions, which also affects the discharge capacity of the battery. Generally, it is placed upright. If it is placed upside down or tilted, it will affect the discharge capacity of the battery, because it will reduce the contact area between electrolyte and lithium tape. The maximum continuous discharge current is 200mA, and the maximum pulse discharge capacity is 400mA, but this is related to the pulse characteristics of the battery, as well as the use conditions such as temperature and battery use state. The weight is about 1 06g, which belongs to dangerous goods and is restricted by transportation safety regulations, because the weight of lithium tablets inside the battery is much greater than1g..
