Step 3
Load test
1.Connect voltmeter and ampere load equal to ½ the cold cranking
amperes(18℃) rating of the battery for 15 seconds.
2. Observe voltage at 15 seconds with load on.Disconnect load
3.Place thermometer in one cell to take temperature of electrolyte.
4.Refer to voltage table
Voltage below table value Voltage equal to or above table
