NOTE:
Since MF batteries are sealed, it is not possible
to check the charge state of the battery by mea-
suring the specific gravity of the electrolyte.
Therefore, the charge of the battery has to be
checked by measuring the voltage at the bat-
tery terminals.
1. Remove:
8 mat
8 battery cover
8battery holder
Refer to "COVER AND PANEL".
2. Disconnect:
8 battery leads
(from the battery terminals)

First, disconnect the negative battery lead
1 1 1 1 1 , and then the positive battery lead 2 2 2 2 2 .
3. Remove:
8 battery
4. Check:
8 battery charge

a. Connect a digital pocket tester to the bat-
tery terminals.

NOTE:
8 The charge state of an MF battery can be
checked by measuring its open-circuit volt-
age (i.e., the voltage when the positive ter-
minal is disconnected).
8 No charging is necessary when the open-
circuit voltage equals or exceeds 12.8 V.
