BATTERY INSPECTION INSP ADJ NOTE: Since MF batteries are sealed, it is not possible to check the charge state of the battery
of MF battery can be checked by measuring its open-circuit voltage (i.e the voltage when the positive terminal is disconnected)S
No charging is necessary when the open-circuit voltage equals or exceeds 12.8 VS Check the charge of the battery, as shown
in the charts and the following exampleExample Open-circuit voltage12.0 Charging time6.5 hours Charge of the battery20 30
Open-circuit voltage (V) 13.0 12.5 12.0 11.5 Relationship between the open-circuit voltage and the charging time at 20_C
5 6.5 10 Charging time (hours) These values vary with the temperature, the condition of the battery plates, and the electrolyte
