INSPECTING THE BATTERY
NOTE: For a proper inspection of the battery, carry out each part of the inspection until the actual state of the battery is known.
Visual inspection
- Check that the cable connections are clean and tightened properly. Remove all foreign bodies from the top of the battery.
- Check the box, the terminals and the battery cables for damage.
- Check the electrolyte level, see page 4.
- If you have added water to the battery, charge the battery for 15 minutes at 15 to 25 amperes to allow the water to mix correctly with the electrolyte.
Check the specific gravity
Use a battery hydrometer to check the specific gravity of the electrolyte. The specific gravity indicates the charge level in each cell.
Battery hydrometers are designed to indicate the correct specific gravity when the electrolyte is at a temperature of 26.7°C.
Before checking the specific gravity, check the electrolyte temperature. If the hydrometer is not equipped with a thermometer, use a thermometer to measure the electrolyte temperature. The thermometer has to be calibrated at least up to 52°C.
1. Remove sufficient electrolyte from a cell so that the float moves freely in the tube.
NOTE: If it is not possible to check the specific gravity without first adding water to the cell, charge the battery for 15 minutes at 15 to 25 amperes to allow the water to mix correctly with the electrolyte. Then, check the specific gravity.
2. Read the float.
3. Read the thermometer, if the reading is greater than 26.7°C, add specific gravity points to the reading to get the specific gravity. If the reading is less than 26.7°C, deduct specific gravity points from the reading to get the specific gravity. See the illustration below and add or deduct specific gravity points depending on the situation.
4. Record the corrected specific gravity for each cell.
5. If the difference between the high and low readings is 0.050 minimum, charge the battery and check the specific gravity again. If after charging the difference is still 0.050 minimum, install a new battery.
NOTE: When the battery is replaced, do not use a used battery with a new one. The life of the new battery will be reduced.
