3.7.3 Checking the acid batteries
TEST OF DENSITY OF ELECTROLYTE
1. Do not add water
2. Using the electrolyte, rinse the density meter at least 3 times before taking a sample
3. Fill the densimeter so that the oscillating part of it is completely supported by the liquid
4. Repeat the operation on all cells
5. Compare the readings of the various cells and check the charge condition of the batteries with the table
The readings should all be at the value of the following table
±
0.007. If any reading is lower, proceed as follows:
1. Check the battery voltage
2. Fully charge the battery
3. Repeat the electrolyte density reading
If the measured density is even lower, an equalization cycle can be attempted (if the charger allows it). If in
any case the measured density of all or some of the cells is less than the value 1.227 it means that:
1. The battery is probably at the end of its life
2. The battery was left without charge for too long
3. Part of the electrolyte was lost during a refill
4. A cell is defective or has leaks
5. The addition of water was excessive just before the test
