Despite the fact that modern industry produces maintenance-free batteries, it will not be superfluous to check the electrolyte in the battery and make sure of its quality.
Necessary
- Glass tube with a diameter of 5 mm,
- hydrometer.
Instructions
Step 1
One of the tasks when checking the electrolyte will be to measure its level in each jar. In order to complete the task, it is necessary to tear off the packaging film and unscrew the caps in each can. Then a glass tube is taken into the hands and immersed at one end in the electrolyte, reaching the separator, the upper opening of the tube is tightly closed with a thumb, and in this state it is removed from the battery jar.
Step 2
If the electrolyte level in the battery is correct, the tube must be filled at least 10 mm. In cases where the level is insufficient, then this is considered a factory defect.
Step 3
The next step is to check the density of the electrolyte poured into the battery. To achieve the goal, we take a hydrometer in our hand and take electrolyte from each bank of the battery in turn. If it is found that the density of the electrolyte in the battery banks does not correspond to the norm or it turns out that it is below 1.27 units, then such a battery should not be purchased.
