As practice shows, not everyone who is interested in the question of how much electrolyte is in a battery knows what an electrolyte is and why it is needed, so now you will receive answers to all the questions voiced. So, first things first.
What is an electrolyte and why is it needed at all?
The electrolyte is a solution of sulfuric acid and plain distilled water. They are filled with lead-acid batteries in the right concentration and volume so that they can store energy due to the chemical processes that occur with this solution. Hence, if the concentration or amount of electrolyte in the battery decreases, it ceases to fully cope with its duties and begins to need to be replaced or restored. In the latter case, the question arises before motorists: how much electrolyte should be in the battery.
So, how much electrolyte should be in the battery?
How much electrolyte a car battery should contain for its most efficient operation is directly determined by its capacity. Of course, depending on the manufacturer, some difference is possible, but in general, the volume of electrolyte for batteries of different capacities will be as follows:
- 55 Ah - 2.5 l +/- 100 g;
- 60 Ah - 2.7-3 l;
- 62 Ah - about 3 l;
- 65 Ah - about 3.5 liters;
- 75 Ah - 3.7-4 l;
- 90 Ah - 4.4-4.8 l;
- 190 Ah - about 10 liters.
But this is only an approximate displacement, it is needed more for reference before going to the store. In the process of restoring the battery, you need to focus not on it, but on the special marks present on the body of the latter. Now more.
What should be the electrolyte level in the battery?
If your battery has a scale with a minimum and maximum, then the question of what level the electrolyte should be filled in is solved very simply - along the top line, that is, up to the “MAX” mark,
If there is no such scale, it is possible that there are “tongues” in the holes of your battery, then the electrolyte in the battery needs to be poured so much that they are covered with a 5 mm layer of solution (completely immersed in it).
Well, if there is neither one nor the other, fill the electrolyte into the battery in the volume recommended above (it should not be to the eyeballs, but a little less), and then for self-control, take a glass tube with a diameter of up to 5 mm and lower it inside the battery, until it hits the safety shield. Close the top opening of the tube with your finger and pull it out. If the level of electrolyte remaining in it is within 10-15 mm, you did everything right - the electrolyte level in the battery is optimal.
