Checking Electrolyte Level
Check the level of electrolyte before each startup.
Remove filler caps and check to see that electrolyte
level is up to bottoms of filler holes. See Figure 3-14.
Refill as necessary with distilled water or clean tap
water. Do not add fresh electrolyte! Be sure filler caps
are tight.

Checking Specific Gravity
Useabatteryhydrometertocheckthespecificgravityof
the electrolyte in each battery cell. While holding the
hydrometer vertical, read the number on the glass bulb
atthetopoftheelectrolytelevel. If the hydrometerused
does not have a correction table, use the one in
Figure 3-15. Determine specific gravity and electrolyte
temperature of battery cells. Locate temperature in
Figure 3-15 and adjust specific gravity by amount
shown. Thebatteryis fullycharged ifthe specificgravity
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. The battery should be
charged if the specific gravity is below 1.215 at an
electrolyte temperature of 80°F (26.7°C).
