9.0 Specific 

Gravity 

 

Before taking specific gravity readings, ensure that the electrolyte level is at the “MAX” line and that any 
recent topping-up of de-ionized water has properly been mixed by an equalize charge (see section 8.4.2). 

 

The specific gravity of the electrolyte varies with temperature.  Consequently, hydrometer readings should 
be corrected as follows: 

 

For every 3°F above 77°F, subtract 1 point (0.001) from the hydrometer reading. 

 

For every 3°F below 77°F, add 1 point (0.001) to the hydrometer reading. 

 

The metric equivalent correction is 1 point (0.001) for every 1.5°C. 

 

The specific gravity of the electrolyte in new cells should be as per section 5.0.  Over time there may be a 
slight fall in the maximum specific gravity values obtainable at the end of charge.   The specific gravity 
may range ± 0.01 points within a cell at the nominal temperature of 77 F (25°C). 

NEVER TRY TO INCREASE SPECIFIC GRAVITY READINGS BY ADDING ELECTROLYTE 
UNLESS DIRECTED TO DO SO BY THE MANUFACTURER. 

10.0 Maintenance 

 

Proper maintenance will prolong the life of the battery and will aid in ensuring that it is capable of 
satisfying its design requirements.  A good battery maintenance program will serve as a valuable aid in 
maximizing battery life, preventing avoidable failures, and reducing premature replacement.  Only 
personnel knowledgeable of batteries and required safety precautions should perform battery 
maintenance. 

 

For regular monitoring of the battery condition, a pilot cell should be selected.  The pilot cell should be 
near the middle of the battery string (for batteries consisting of more than 60 cells, it is advisable to select 
one pilot for every 60 cells). 

 

When measuring voltages, be sure the charger is on and record the voltages to three decimal places. 

10.1 Monthly 

 

Monthly battery inspection must be made while the battery is in normal float condition and should 
include the following activities: 

 

Check the general appearance and cleanliness of the battery, the battery rack and the 
battery area. 

 

Check for cracks in cells or electrolyte leakage. 

 

Check for corrosion at terminals, connectors, or racks. 

 

Record the overall battery float voltage measured at the battery terminals (not at the 
charger). 

 

Record the voltages, temperature and specific gravity of the designated pilot cells. 

 

Check the electrolyte level of the cells. 

 

Clean and dry the cell lids and connectors using anti-static cloths 

 

Inspect the charging system, ambient temperature and ventilation 

 Take 

corrective 

actions, as required, in accordance with IEEE standard 

450 – 

Recommended Practice for Maintenance, Testing, and Replacement of Vented Lead-
Acid Batteries for Stationary Applications 

10.2 Annually 

 

Annual battery inspection must be made while the battery is in normal float condition and should 
include the following activities: 

 

Check the general appearance and cleanliness of the battery, the battery rack and the 
battery area.
