Volt meter
Relationship between open-circuit
voltage and charging time at 20_C
(68_F)
*This varies depending on the temperature, the state of
charge in battery plates and the electrolyte level.

CAUTION:
*****************************************************
NOTE:
D Batteries generate explosive hydrogen
gas. Always follow the following preven-
tive measures:
D Charge batteries in a well-ventilated area.
D Keep batteries away from fire, sparks or
open flames (e.g., welding equipment,
lighted cigarettes, etc.)
D DO NOT SMOKE when charging or han-
dling batteries.
KEEP BATTERIES AND ELECTROLYTE OUT
OF REACH OF CHILDREN.
1. Remove:
D Mat (right)
D Cover (battery case)
Refer to “COVER AND PANEL” section.
2. Disconnect:
D Battery leads
Disconnect the negative lead
1
first and
then disconnect the positive lead
2
.
3. Remove:
D Battery
4. Check:
D Battery condition
Battery condition checking steps:
D Connect a digital voltmeter to the battery ter-
minals.
Tester (+) lead ! Battery (+) terminal
Tester (-) lead ! Battery (-) terminal
The charge state of an MF battery can be
checked by measuring the open-circuit voltage
(i.e. the voltage when the positive terminal is
disconnected).
Open circuit voltage Charging time
12.8 V or more No charging is neces-
sary.
