3. Specific gravity inspection
Hint:
The application of hydrometer please refers to “Chapter 53 Battery-Electrolyte, Preparation).
The following is a comparison table measured by hydrometer

Specific gravity value Judgment Treatment
Adjust the specific gravity by
Above 1.300 Wrong liquid is filled deionized water (refer to “Chapter 53
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
Over discharged or there is
Under 1.100 ～ 1.220 to “Chapter 53 Battery-Battery,
malfunction
Application and maintenance”)
Initial charge and then inspect (refer
Specific gravity difference of The cell may be have malfunction to “Chapter 53 Battery-Battery,
every cell is above 0.04
Application and maintenance”)
4. Voltage inspection
The following is a comparison table measured by digital multimeter

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”)
