Saft PN 40074 K
NSN 6135 15 116 9327
Technical Specification:
ST 244009
The V616 battery is specifically
dedicated to the power supply for
the propulsion and electronics of
A244 torpedoes (mod 0, mod 1,
mod 2) produced by Whitehead
Alenia Systemi Subacquei and
commercialised by EUROTORP.
used by 14 different navies
worldwide, in particular in South
America, Asia, Southern and
Northern Europe.
The battery is a bipolar stack of
146 cells. Each cell is made of
one silver chloride electrode, and
one magnesium (alloy) electrode
separated by plastic plots spacers.
Storage conditions
The storage life of V616 batteries
is the same as the storage life of
MK61 batteries:
The battery is stored without
electrolyte, and activated by sea
water after the torpedo has been
launched through a scoop located
in the hull of the torpedo. During
the run of the torpedo, a
continuous flow of electrolyte will
remove the heat, the gas, and the
mineral mud produced by the
discharge and corrosion reactions.
A244 torpedoes using V616
batteries have been successfully
