A reserve battery, also called stand-by battery, is a primary battery where part is isolated until the battery needs to be used. When long storage is required, reserve batteries are often used, since the active chemicals of the cell are segregated until needed, thus reducing self-discharge. [1]A reserve battery is distinguished from a backup battery, in that a …

Operating Principle. The activation of the thermal battery consists of a chain of events as follows. Thermal battery is activated when the heat pellets (pyrotechnic) located in each cell are ignited by the heat train (center-hole and side heat strips) and the burning is initiated by an electrical pulse to the squib.
The battery activation reduces losses and ensures sufficient power during use. Also battery activation also extends its life, helping to use and store it properly. The self-discharge of the battery is …
