A battery hydrometer is used to check the state of cost of a battery cell. That is carried out by measuring the density of the electrolyte, which is completed by measuring the particular gravity of the electrolyte. The higher the focus of sulfuric acid, the extra dense the electrolyte turns into. The upper the density, the upper the state of cost. Particular gravity is the measurement of a liquid that’s in comparison with a baseline. The baseline is water which is assigned a base variety of 1.000. The focus of sulfuric acid to water in a brand new golf automotive battery is 1.280 which implies that the electrolyte weighs 1.280 occasions the burden of the identical quantity of water. A completely charged battery will check at 1.275 – 1.280 whereas a discharged battery will learn within the 1.140 vary. ! NOTE !

Don’t carry out a battery hydrometer check on a battery that has simply been watered. The battery should undergo no less than one cost and discharge cycle to be able to allow the water to adequately combine with the electrolyte. The temperature of the the hydrometer studying have to be corrected to 80° F (27°C). You will need to acknowledge that the electrolyte temperature is considerably completely different from the ambient temperature if the automobile has been operated.

1. Draw electrolyte into the hydrometer a number of occasions to allow the thermometer to regulate to the electrolyte temperature and notice the studying. Look at the colour of the electrolyte. A brown or grey coloration signifies an issue with the battery and is an indication that the battery is nearing the tip of its life.

2. Draw a full pattern of electrolyte into the hydrometer to allow the float to drift freely.

3. Maintain the hydrometer in a vertical place at eye stage and notice the studying the place the electrolyte meets the dimensions on the float.

4. Add or subtract 4 factors (.004) to the studying for each 10° F (6° C) the electrolyte temperature is above or under 80° F (27° C). Regulate the studying to adapt with the electrolyte temperature, e.g., if the studying signifies a particular gravity of 1.250 and the electrolyte temperature is 90° F (32° C), the 1.250 which supplies a corrected studying of 1.254. Equally if the temperature was 70° F (21° C), subtract studying of newurbanhabitat.com factors (.004) from the 1.250 to provide a corrected

  • 5. Take a look at every cell and notice the readings (corrected to 80° F or 27° C). A variation of fifty factors between any two cell readings (instance 1.250 – 1.200) signifies an issue with the low studying cell(s).
  • 12.60 to 12.74 = 85 to 100% Charged
  • 12.40 to 12.59 = 75 to 85% Charged
  • 12.20 to 12.39 = 50 to 75% Charged
  • 12.00 to 12.19 = 25 to 50% Charged
  • 12.00 & Beneath = Absolutely Discharged

As a battery ages the particular gravity of the electrolyte will lower at full cost. This isn’t a cause to exchange the battery offering all cells are inside fifty factors of one another.

Because the hydrometer check is in response to a automobile exhibiting a efficiency drawback, the automobile ought to be recharged and the check repeated. If the outcomes point out a weak cell, the battery or batteries ought to be eliminated and changed with an excellent battery of the identical model, sort and approximate age.
