up voltage
Use multi-meter
check total voltage
across positive and
negative terminal
1.The value of measured
and displayed on
equipment should be
close.
2. Voltage error after
compensation should be
less than ±50mV
Adjust the charging voltage to recom
mended range if there is a deviation;
Repair the equipment if voltage can’
t be adjusted.

①
Float
voltage
for each
battery
Measure the voltage of
each battery under floatin
g, using a meter with four
and half digits.
Voltage difference
less than
2V: 90mV
6V: 240mV
12V:480mV
If there is a deviation, discharge the
batteries and perform a equalizing ch
arging, observe for one through two
months under floating. Contact us if
no improvement.
②
Correct
the
low
voltage
batteries
If more than two cells’
voltages are less than
2.16V/cell after
temperature adjustment,
the batteries need
equalization charging.
Float voltage
≥
2.16V/cell
If battery float voltage less than
2.16V/cell after equalization charge,
the battery need do a 80% capacity
test.
③
Activated
discharge
Perform a discharge-char
ge cycle, using lower
level of equalizing charge
voltage for the charge.
Discharge around
30% of the
nominal capacity.
Perform the discharge-charge cycle if
no power-off for six months.
