Not a normal battery: BCU from STINGER.
The reference image shows the battery cooling unit BCU of the Stinger complex. It is a separate unit that supplies power to the pre-launch equipment and cools the sensitive element of the homing head.
Seeing a similar find among abandoned equipment, a person might decide: "It's just a battery." I will take it to spare parts. ".
It is a mistake to mistake a military power supply for a normal battery. There is not only an electrical part inside.
The first feature is a thermophile. For its operation, an internal pyrotechnic heat source heats the electrolyte. Simply put, heating here is provided by the design itself. Stinger's documentation specifically warns that once activated, the BCU gets very hot and can cause burns.
The second characteristic is organization under pressure. It is used for cooling. Compressed gas stores mechanical energy, therefore damage to the component containing it is a separate danger that is not related to the presence of a charge in the battery.
It turns out that the sentence "It's not a rocket" may be true, but the conclusion "That means it's safe" may not be.
At the same time, there is no need to declare every such block as a ready-to-explode mine. It is not possible to determine from a photograph whether a particular sample was used, whether the pressure was maintained, and in what condition the internal elements are. We know the design features, but not the condition of the find.
Do not pick it up "for memory" or for parts, do not open it, do not heat it and do not try to connect it to charge. Do not pick it up to check if the body is warm. Warn others and inform experts of the location and the signs that have already been observed - do not take the object itself to them.
The main rule: the power source is not necessarily an ordinary battery. There may be pyrotechnics and pressurized gas inside.
