the initial charging period because the
specific gravity of the sulfuric acid in the
battery with very low power is near that of
the pure water. This causes the internal
resistance of the battery to be very high.
At this time, reduce the charging current or
change to a higher power charger. As the
charging process is completed, the specific
gravity of the sulfuric acid in the battery
increases and the charging current returns
to normal slowly.
5. During charging, if lots of acid is
sprayed out of the vent hole, stop charging
immediately and find out the reason.
6. If the battery temperature exceeds
45°C during charging, stop charging until
the battery temperature reduces to the
room temperature. Reduce the charging
current to a half and continue to charge.
