Magnesium-silver chloride
seawater-activated battery
Type V616 for A244 torpedoes
The V616 battery is specifically dedicated to the power supply for the propulsion and electronics
of A244 torpedoes (mod 0, mod 1, mod S) produced by Whitehead Alenia Systemi Subacquei.
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
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 used by 14 different
navies worldwide, in particular in South
America, Asia, Southern and Northern
Saft is the sole qualified supplier of the
V616 battery for A244 torpedoes.

Technical specification
The performances of the V616 battery will
vary with the sea water temperature and
salt concentration.
The V616 battery delivers a nominal
power of 32 kW under a nominal voltage of
160 Volts and for a duration of 6 minutes.
During the discharge the voltage of the
battery will decrease from a maximum
of 190 V (peak voltage), to a minimum of
140 V (cut-off voltage).
These performances are corresponding to
a battery discharged in sea water at 16°C
with a salinity of 38g/l.
