How to check the electrolyte density of the battery?
When using the car, its owner is constantly faced with the need to service and replace the battery. Such a battery has an increased load, so over time, the battery begins to hold the charge worse, requiring an appropriate replacement. The efficiency of the car battery is directly influenced by the electrolyte density. It is necessary to check on a regular basis the density indices of the electrolyte, which will ensure the trouble-free start of the engine, and the battery itself will last for as long as possible, without any trouble. In this article, we will tell you how to check the density of the battery.
Before telling yourself about how to check the density of electrolyte in the battery, let’s talk about the device of standard car batteries. Such a battery consists of:
Cases consisting of six cans.
Pluses and minuses of lead plates located inside each jar.
The plus and minus tires, which connect each sealed compartment.
Serial connection, which allows you to get the required power output at the output.
The battery is obliged to give electrochemical parameters of electrolyte by its ability to give and accumulate electric charge. Such an electrolyte pours into each of the tight cans and has certain density indicators. During the operation of the machine, the density indicator may change, so the car owner needs to know how to check the battery density at home and, if necessary, increase or decrease this figure.
How to handle the battery properly
The trouble-free operation of such a car battery depends on the timeliness and correctness of the battery maintenance. Such works include:
Analysis of electrolyte level.
Battery density check.
Check the battery with the load fork.
This battery check must be carried out twice a year – in spring and autumn. This will allow to provide high-quality battery operation both in summer and in winter in frost. The maintenance and proper care of the battery is not particularly difficult. If the density of the electrolyte is higher than normal, it is necessary to add distilled water. If there is a low density, then you just have to recharge the battery.
The principle of operation of the battery
The battery in the car runs cyclically, that is, first the battery accumulates charge, after which it gives it when it is required to start the engine. During such cycles there is a chemical reaction inside the battery, when various salts are deposited from sulfuric acid, which settle down on the plates of lead, and water from the electrolyte can be released. Over time, the concentration and density of the electrolyte varies, which results in improper operation of the battery. Periodic density measurement will prevent the battery from being discharged, which will last as long as possible. Let’s talk more about how to check the density of the battery with the hydrometer.
Attention If the density index turned out to be below normal, then the electrolyte should not be added to the battery. It is necessary to recharge the battery, which will provide the necessary density indicator.
The principle of operation of the car battery
How and why is the electrolyte density measured?
Many car owners simply do not know for what it is necessary to measure the density of electrolyte in the accumulator. As is known, electrolyte consists of 35% of sulfuric acid and 65% of distillate. This ratio makes it easy to accumulate the charge, without causing any harm to the lead plates. During operation, the density of the electrolyte may vary, which is due to the evaporation of distilled water and chemical reactions during operation of the battery. As a result, the content of sulfuric acid increases, which, in turn, worsens the charge and can damage lead plates, up to the full entry into the battery life.

What is bad in high and low density?
Low density leads to a battery discharge, which prevents the use of the car. High density, that is, increased content of sulfuric acid, corrodes plates that quickly become disadvantageous.
Check the electrolyte level
Before checking the density of the battery without a hydrometer it is necessary to set its level. In the event that the battery itself is made of translucent plastic, then checking the electrolyte level is not difficult. If the battery is made of opaque dark plastic, a special glass tube with a diameter of about 5 millimeters will be required to check the electrolyte level. This tube is lowered into the jar until it stops, after which its top hole is closed with a finger. The tube is gently pulled out of the battery. In it there will be an electrolyte, which is poured into a flask and check the level. It is believed that the norm of fluid in the flask will be 10-15 millimeters. In the event that the level is greater or less
