CHECKING AND CHARGING THE BATTERY

NOTE:

Since MF batteries are sealed, it is not possi-

ble to check the charge state of the battery by

measuring the specific gravity of the electro-

lyte. Therefore, the charge of the battery has to

be checked by measuring the voltage at the

battery terminals.

1. Lift the hood up.

2. Remove:

• battery case cover

3. Disconnect:

• battery leads

CAUTION:

First, disconnect the negative battery lead

, and then the positive battery lead

4. Remove:

• battery

5. Check:

• battery charge

a. Connect a pocket tester to the battery termi-

nals.

NOTE:

• The charge state of an MF battery can be

checked by measuring its open-circuit volt-

age (i.e., the voltage when the positive termi-

nal is disconnected).

• No charging is necessary when the open-cir-

cuit voltage equals or exceeds 12.8 V.

b. Check the charge of the battery, as shown

in the charts and the following example.

Example

c. Open-circuit voltage = 12.0 V

d. Charging time = 6.5 hours

e. Charge of the battery = 20 ~ 30%

Relationship between the open-circuit voltage and the

charging time at 20 °C (68 °F)

These values vary with the temperature, the condition of the battery

plates, and the electrolyte level.
