Checking Specific Gravity
Usea batteryhydrometertocheck thespecificgravityof
the electrolyte in each battery cell. While holding the
hydrometervertically,readthenumberontheglassbulb
atthetopoftheelectrolytelevel (orthenumberadjacent
to the pointer). If the hydrometer does not have a
correction table, use the table in Figure 3-16.
Determine specific gravity and electrolyte temperature
of battery cells. Locate temperature in Figure 3-16 and
adjust gravity by amount shown. The battery is fully
charged if the specific gravity is 1.260 at an electrolyte
temperature of 80°F (26.7°C). The difference between
specific gravities of each cell should not exceed ±0.01.
Charge the battery if the specific gravity is below 1.215
at an electrolyte temperature of 80°F (26.7°C).
NOTE
Some battery testers have four or five beads in the test
tube. Draw electrolyte into the tube as done with the
hydrometer described previously. Use the
manufacturer’s instructions. Figure 3-15 interprets the
test results.
