Thermal batteries offer the designer the highest energy density in a package that can be stored for many years prior to use. When called upon to power the weapons system they stand ready to deliver their energy.
An energy impulse from an external source activates the thermal battery and ignites pyrotechnic materials within the battery to melt the electrolyte. The battery activates and produces high power for a short period of time .
HBL’s thermal batteries are custom designed to meet the requirements for short and long range missiles, torpedo engine priming, rockets and guided bombs.
