OPEN-CIRCUIT VOLTAGE TEST A battery open-circuit voltage (no load) test will show Before proceeding with this test, completely charge 1. Before measuring the open-circuit voltage, the sur- face charge must be removed from the battery. 2. Disconnect and isolate both battery cables, nega- tive cable first. 3. Using a voltmeter connected to the battery posts (see the instructions provided by the manufacturer See the Open-Circuit Voltage Table. This voltage reading will indicate the battery state-of-charge, but will not reveal OPEN CIRCUIT VOLTAGE TABLE Open Circuit Voltage Charge Percentage 11.7 volts or less 0% 12.0 volts 25% 12.3 volts 50% 12.6 volts 75% 12.8 volts or more 100% 8F - 14 BATTERY SYSTEM ND |
