GENERAL INFORMATION
M2544200200383
The sealed battery is installed in the trunk room. The
sealed battery has a structure that uses the sealed
reaction (cathodic absorption), eliminating the needs
for refilling and liquid level check.
• The sealed reaction (cathodic absorption) brings
the oxygen gas
*
, which is generated at positive
pole, to the negative pole, and binds the oxygen
gas with hydrogen gas generated at negative
pole. As a result, the gas is transformed back to
water, preventing the decrease of electrolytic
solution.
NOTE:
*
: The generation of oxygen gas at posi-
tive pole occurs in an earlier stage than that of
hydrogen gas at negative pole.
• Calcium alloy with superior characteristics of
electrolyte decrease is used for the polar plate
grille between the positive and negative poles in
the battery container.
Although the sealed reaction (cathodic absorption)
occurs with 100% efficiency with a normal use, the
generated gas may not be absorbed completely
under the statuses of overcharging, high tempera-
ture, or high voltage. Therefore, to prevent the charg-
ing of non-absorbed inflammable gas inside the trunk
room, the battery exhaust tube (battery cover hose)
and pipe for gas bleeding are equipped.
