WARNING
CAUTION:
3. Charge:
S
battery
(refer to the appropriate charging method il-
lustration)
Do not quick charge a battery.
S
Make sure that the battery vent is free of
obstructions.
S
Never remove the MF battery sealing caps.
S
Do not use a high-rate battery charger.
They force a high-amperage current into
the battery quickly and can cause battery
overheating and battery plate damage.
S
If it is impossible to regulate the charging
current on the battery charger, be careful
not to overcharge the battery.
S
When charging a battery, be sure to re-
move it from the snowmobile. (If charging
has to be done with the battery mounted on
the snowmobile, disconnect the negative
lead from the battery terminal.)
S
To reduce the chance of sparks, do not
plug in the battery charger until the battery
charger leads are connected to the battery.
S
Before removing the battery charger lead
clips from the battery terminals, be sure to
turn off the battery charger.
S
Make sure that the battery charger lead
clips are in full contact with the battery ter-
minal and that they are not shorted. A cor-
roded battery charger lead clip may gener-
ate heat in the contact area and a weak clip
spring may cause sparks.
S
If the battery becomes hot to the touch at
any time during the charging process, dis-
connect the battery charger and let the bat-
tery cool before reconnecting it. Hot batter-
ies can explode!
S
As shown in the following illustration, the
open-circuit voltage of a MF battery stabi-
lizes about 30 minutes after charging has
been completed. Therefore, wait 30 min-
utes after charging is completed before
measuring the open-circuit voltage.
