Battery
Connections
Connections to battery posts must be made with permanent connectors
that provide a reliable, low-resistance connection. Do not use alligator
clips. Clean the connections regularly and prevent corrosion by using a
protective spray coating or Vaseline.
Battery State of
Charge
You can measure battery state of charge with a hydrometer or
approximate state of charge with a voltmeter. Use a digital voltmeter that
can display tenths or hundredths of a volt when measuring 10 to 30 volts.
Make your measurements when the battery has not been charged or
discharged for several hours. For a deep-cycle battery at 77º F (25º C), use
the following table:
Battery Voltage
State of Charge
12.7–13.0 V
100%
12.5–12.6 V
80%
12.3–12.4 V
60%
12.1–12.2 V
40%
11.9–12.0 V
