Amadas 9980 - Specific Gravity Check

9980 Self-Propelled Peanut Combine Electrical System Service
Specific Gravity Check
Check specific gravity of electrolyte in each
cell with a battery hydrometer to meter battery
condition. Charge battery if reading is below
1.225. Replace battery if difference between
cells is more than 0.050.
Always correct specific gravity reading for
electrolyte temperature variation. Add 0.0004
for every 10ºC above 27ºC). Subtract at same
rate in electrolyte temperature is below 80ºF
(27º
C). Corrected specific gravity of a fully
charged battery is 1.260.
CAUTION
Batteries must be on a flat surface to
accurately check fluid levels. Battery fluid
level should be visible at the top of each fill
port covering the plates in each cell.
Battery gas can explode. Keep sparks and
flames away from batteries. Use flashlight
to check battery electrolyte level.
NEVER check battery charge by placing a
metal object across the posts. Use a
voltmeter or hydrometer.
