Battery-Battery

8. Measure it by instrument after charging, and confirm if the battery resume to
standard value by specific gravity method, voltage method or capacity method.
(a) Specific gravity method

Specific gravity value Judgment Treatment
Adjust the specific gravity by
Concentration of electrolyte is
Above 1.300 deionized water (refer to “Chapter 53
overhigh or the wrong liquid is filled
Battery-Electrolyte-Preparation”）
1.250 ～ 1.280 Good Continue to use

Charge (refer to “Chapter 53
1.220 ～ 1.250 Undercharge Battery-Battery, Application and
maintenance”)
Initial charge and then inspect (refer to
Over discharged; concentration is
Under 1.100 ～ 1.220 “Chapter 53 Battery-Battery,
too low
Application and maintenance”)
Initial charge and then inspect (refer to
Specific gravity difference of
The cell may be have malfunction “Chapter 53 Battery-Battery,
every cell is above 0.04
Application and maintenance”)
(b). Voltage method
Voltage Judgment Treatment

Above 12.5 V Good Continue to use
Charge (refer to “Chapter 53
11.5 ～ 12.5 V Undercharge Battery-Battery, Application and
maintenance”)
Initial charge and then inspect (refer to
Over discharged or inside
Under 11.5 V “Chapter 53 Battery-Battery,
malfunction Application and maintenance”)
(c). Capacity method
Indication of the capacity
Judgment Treatment
meter

White area Sufficient Continue to use
Green area Good Continue to use

Charge (refer to “Chapter 53
Yellow area Undercharge Battery-Battery, Application and
maintenance”)
Initial charge and then inspect (refer to
Read area Over discharged “Chapter 53 Battery-Battery,
Application and maintenance”)
