1. Specific gravity 1.265
A hydrometer measures the charge of a battery in
terms of specific gravity of the electrolyte. Most
hydrometers give a true reading at 25°C(77°F).
In order to obtain correct readings, adjust the ini-
tialreadingbyadding.001tothehydrometerread-
ings for each 2°C(3°F) above 25°C(77°F) and by
subtracting .001 for every 2°C(3°F) below 25°C
(77°F).
This chart will be useful to find the correct reading.
