7. Hydrometer check The hydrometer is used to check the degree of acidity in the battery plates. If the acid is weak, the battery is working properly. For best results, buy a hydrometer with a thermometer. You will find some models that adjust themselves, while some come with a conversion...

You might want to take a reading with a hydrometer to get the gravity of your juice so you can work out the ABV. It's time to add the yeast but what kind should you add? The classic, traditional yeasts to use are commonly referred to as Champagne yeast as they produce what is often...
Step 2: If the battery is conventional (has three or six caps on top), use a hydrometer to check the density of the liquid electrolyte in each cell. The density or specific gravity should be between 1.26 and 1.28 at room temperature. If it's below 1.25, recharge the battery. The diffe...
To check the condition of your RV batteries, you can test the voltage of each battery using a multimeter. Using a hydrometer, you can also check the specific gravity of the electrolyte in flooded lead-acid batteries. Conduct either or both of these tests when the battery is fully charged an...
If you are using a hydrometer to check the concentration of antifreeze in the coolant, keep in mind that the specific gravity of conventional EG antifreeze is different from that of PG (which has a density close to water). So if someone has added the "less-toxic" PG antifreeze to the co...
You can alsouse the hydrometer to work out the alcohol content of your beer. Make sure you take your readings! Going through this exercise really improved my understanding of part of the science behind making beer. 7. Good things come to those who wait ...
Stop the charge when two hydrometer or voltage readings recorded two hours apart indicate no increase. Never attempt to charge a frozen battery. Allow it to warm to 60°F before charging. Always use Automatic Battery chargers when using Connect-Ease products. ...
