BatteryMaintenance
TestingTheElectrolyteSolution
Thegeneralconditionofabatterycanbedeterminedbymeasuringthespecificgravityoftheelectrolyte solutionandadjustingthereadingto80°F(27°C).Iftheelectrolytelevelistoolowtoallowtakinga hydrometerreading,addmake-upwatertothecorrectlevelandthenchargethebattery2to4hoursbefore takingareading.
1.Insertthehydrometerintoacell.Fillthehydrometerbarrelwhileholdingitvertically.Thefloatmustnot dragonthewallofthebarrel.
2.Readthehydrometer:
1.250orabove-fullychargedbatterycell
1.250-1.225-fulltohalfchargedbatterycell
1.225-1.150-halftolowchargedbatterycell

3.Testeachcellinthesamemanner.
MEASURINGSPECIFICGRAVITY
4.Ifthereismorethan.050(50gravitypoints)variationbetweenthehighestandlowestreading,thebattery shouldbereplaced.
5.Adjustthereadingsto80°F(27°C).
a.Forevery10F°(5.5C°)theelectrolytetemperatureisabove80°F(27°C),add.004(4gravitypoints)tothe specificgravityreading.
Example:Electrolytetemperature=100°F;38°C
Correctedtemperature=80°F;27°C
Difference:=20°F;11°C
Increments:10;5.5
20÷10=2;11÷5.5=2

Add8gravitypointstoyourhydrometerreadingtoobtaintheadjustedreadingat100°F.Iftheuncorrected hydrometeris1.240thecorrectedreadingwouldbe:1.240+8,or1.248
b.Forevery10F°(5.5C°)theelectrolytetemperatureisbelow80°F(27°C),subtract.004(4gravitypoints) fromthespecificgravityreading.
Example:ElectrolyteTemperature=10°F;-13°C
Correctedtemperature=80°F;27°C
Difference=70°F;40°C
Increments:10;5.5
70÷10=7;40÷5.5=7
7×4gravitypoints=28gravitypoints

CheckingElectrolyteLevel
Checktheelectrolytelevelofeachcellandthegeneralconditionofthebattery.
1.Maintaintheelectrolyteleveltothebaseofeachventwell.
2.Themake-upwatermustbeoneofthefollowing(inorderofpreference):
a.Distilledwater.
b.Odorless,tastelessdrinkingwater.
c.Ironfreewater.
d.Anyavailablewater.
ReadingTheAmmeter
1.Afterstartingtheengine,theammeterindicatorshouldregistertotherightofzero,butshouldneverbe "pegged".
2.Aftertheenginehasbeenrunning,theindicatorshouldbejusttotherightofzero.
