①
Total voltage during
recovery charge or

charge
(

(1) Measure total voltage
with voltmeter of 0.5-class
or above.
(2)
Check
voltage
indication value on panel
voltmeter. (
❉5)
(1)
Value
of
equalizing
charge voltage (2.45V/cell) ×
number of cells.
(2) Allowable margin for
panel mounted gauges as
stated in JIS C1102-2
(direct-acting indicator
electric gauges).
(1) When voltage value
deviates from standard,
adjust
by
equalizing
charge voltage(2.45V/cell)
× number of cells.
(2) Repair or replace
gauges deviating over the
allowable degree.
②
Voltage of each cell
duringrecovery charge
or equalizing charge
(
❉4)
Measure
open
circuit
voltage of each cell.
The voltage is measured
from 2 to 24 hours after the
recovery
charge
or
equalizing
charge
was
completed. The voltage of
each cell must be 2.10V or
more. The voltage of any cell
must be within the following
range:
Average
voltage
±0.05V
When the voltage value
deviates from the standard
value, observe for 1 to 2
months, and contact the
manufacturing company.
③
Visual appearance of
storage battery, etc.
Check for presence of
breaking or deformation
damage in battery box, lid,
etc., as well as electrolyte
leakage.
Absence
of
cracking,
deformation
and
other
damage
or
electrolyte
leakage.
In cases of damage or
electrolyte
leakage,
investigate the cause, and
replace
the
battery
containing
anydamaged
items or found to have
electrolyte leakage.
Check for presence of dirt
or stains from dust, etc.
Absence of dirt, stains or
corrosion.
Clean any dirt or stains
with a damp cloth.
Check for evidence of rust Absence of stains or
Clean,
treat
for
