when a battery is fully charged , the amount of sulfuric acid mixed with the water is sufficient to give a specific gravity of about 1.3 when battery is discharged to 50 percent, the specific gravity reading should be 1.2 any specific gravity reading that's less than 1.1 usually indicates a dead batteryThe answer isC. 1.3.
When a battery is fully charged, the amount of sulfuric acid mixed with the water is sufficient to give a specific gravity of about 1.3. The answer is C. I found this on Page 78 of the Mechanics Study Unit of Physical Science (Penn Foster). One of the uses of a hydrometer is to measure the condition of electrolyte solution in a storage battery of the type used in a car. When a battery is fully charged, the amount of sulfuric gravity of about 1.3.

To check the specific gravity of acid in a car battery, you'll need a hydrometer. First, ensure the battery is fully charged and then carefully remove the vent caps. Insert the hydrometer into the electrolyte solution, squeezing the bulb to draw in the liquid, and then release it to allow the float to settle. Read the specific gravity measurement on the scale; a higher value typically indicates a fully charged battery, while a lower value suggests it's discharged.
Yes, the battery is fully charged.
The specific gravity of a discharged lead-acid battery typically ranges from about 1.100 to 1.150. This measurement indicates the density of the electrolyte (sulfuric acid solution) compared to water. A lower specific gravity suggests that the battery is discharged, while a higher value (around 1.250 to 1.300) indicates a fully charged state. Regularly checking specific gravity helps assess battery health and charge levels.
There are two measures, cell voltage and specific gravity of the electrolyte. Cell voltage is the simplest to measure. For most automotive, flooded cell (having liquid electrolyte) batteries, 12.6 volts is considered full charge, although it is typical to have 13 volts or a bit over. The specific gravity of a fully charged battery, measured with a hydrometer, is 1.265.
Specific gravity of the electrolyte in the lead acid cell or battery (assuming that the battery is not of the sealed type) is often used as a measure of its STATE OF CHARGE. Sure we can do the same with a multimeter but the above method is more accurate.
When it is charging the screen reads: Battery Charging. When it is fully charged it reads: Battery Charged.
The relative density of a fully charged battery is typically around 1.28 to 1.3 for lead-acid batteries. This measurement can vary based on the type of battery and its specific composition.
No, a fully charged battery does not weigh more than an empty battery. The weight of a battery remains the same regardless of its charge level.
Laptops that's battery is fully charged does not weigh any more or less than one that's battery is not fully charged. If there is a difference, it would be so small you would not be able to tell.
