It is best to check your new batteries regularly as this will give you a good feel for how often your application will require battery watering. WARNING: A brand new battery may have a low electrolyte level. Charge the battery first and then add water if needed.
It takes quite a bit of energy to bring water to a boil. In fact, you need 1 calorie of energy to raise 1 gram (0.03 ounces) of water by 1 degree Celsius (1.8 degrees Fahrenheit). In order for water to boil, its vapor pressure has to equal the pressure of the atmosphere, Giddings said. That's partly why water boils at a lower temperature on top of Mount Everest than it does at sea level. There's less atmosphere, or lower pressure, pushing down on the water on the mountain, at 29,000 feet (8,800 meters), she said. However, let's envision a pot of water on a burning stove at sea level.
