Design and Function
Our combat torpedo batteries range includes the two following types: SLST-C3 and SLSt-C1. The design of the SLST-C3 battery is based on the well-known SLST-C1 battery. Some important features have been modified in order to meet the demands of the improved torpedo version DM2A3:

The SLST-C1 battery is specifically designed for one-shot operation and long shelf life in non-activated condition. It consists of two independent battery sections. The auxiliary battery section includes 21 Ag-Zn cells and provides power for the electronic systems inside the torpedo.
Safety and Reliability
Safety
and Reliability
The SLST-C3 and SLST-C1 batteries provide our customers with the most reliable and safe combat battery for torpedoes DM2A3 and DM2 A1/ SUT/SST4 torpedoes available in the international market respectively. All components and sub-units, like cells, battery blocks, electrolyte tank, gas tank, activation unit (1W/1A pyrotechnical igniters) and safety electronic device, are embedded in elastic potting material.
Our combat batteries are designed to withstand the specified environmental loads like temperature, shock, and vibration and to serve the torpedo with excellent electrical performance. Both are maintenance free during the whole shelf lifetime.
Shelf Life
The minimum
expected and
specified shelf
life for both
batteries is
10years
With the ABT’s lifetime
extension program the
shelf life of both
batteries can be easily
extended up to
16years
