A:Read the instruction manual carefully before recharging.
B:The batteries should be recharged in well-ventilated areas. Make sure no metal
objects placed on the accumulator. Check all cables connection and connectors
for obvious defects. Observe strictly all safety instructions, e.g. replenishment of the
accumulator and preparation for recharging.
C:Hydrogen will be precipitated in the charging process. So the accumulator room
should be well-ventilated, and the hydrogen content shall be strictly controlled to
ensure safety.
D:For the safety of the cooperation, the forklift should be added protective cover
before using.
Balanced Recharging
After using for a period, voltage and concentration may vary from battery to
battery. Balanced recharging will eliminate the differences so that the performance of
each cell becomes uniformed. In following cases, balanced recharging is necessary:
Voltage of an individual cell is frequently below 1.7V; large current occurs during
discharging, for example, when using the driving motor and lifting motor
simultaneously; for accumulators that are not recharged in time after discharging:
Over discharged accumulators and those are not in use for a long time.
a
、
Recharge with a current of 0.1I5A.
b
、
When the voltage up to 2.5V, and there occur bubbles in the electrolyte, continue
recharging at a reduced current of 0.05I5A.
c
、
Recharge the accumulator to full capacity and stop recharging for half an hour,
and then continue recharging with further-reduced current of 0.025I5A for an hour.
d
、
Stop recharging again for half an hour and continue recharging with a current of 0.025I5A for
an hour.
e
、
Repeat step D until bubbles occurs intensely and instantly when switching on the
charger.
