In this entry we show how to use a battery densimeter, with this tool we can check the state of our lead acid batteries by measuring the electrolyte density.
It consists of a glass measuring cylinder, with an open extension to introduce the liquid to be measured, which is absorbed by the internal vacuum created by the rubber bulb located at the top of the cylinder. Inside it is placed a glass ampoule, closed and filled with air, balanced with weight based on lead pellets.
The ampoule is graduated in densimetric units from 1 to 1.30.
The tests with densimetro should not be made immediately after having filled the glasses with distilled water, but it is necessary to wait until this one has been mixed absolutely with the acid and this is made practically when the battery enters phase of gaseo. with which the ideal is to take densities after several days of having put to level the water
If we have a value lower than of 1,20 the battery is unloaded and of course if the float did not get to move, you can have some problem in the battery. A good performance of the battery is achieved when the density of the electrolyte is between 1.24 and 1.26. For full load it must mark 1,28.
You can purchase the densimeter on our website to make your own measurements and keep the battery in optimal condition. In this way we can measure the state of the electrolyte in lead-acid batteries, such as traction batteries or stationary solar batteries.
