Battery Specific Gravity

For this reason, it is essential to correct the hydrometer readings for temperature. The specific gravity of the electrolyte decreases as the temperature increases, and it increases as the temperature decreases. Hence, it is crucial to measure the specific gravity of the electrolyte at a standard temperature of 25°C (77°F).

Battery Capacity Calculator

As you might remember from our article on Ohm''s law, the power P of an electrical device is equal to voltage V multiplied by current I:. P = V × I. As energy E is power P multiplied by time T, all we have to do to find the energy stored in a battery is to multiply both sides of the equation by time:. E = V × I × T. Hopefully, you remember that amp hours are a measure …
