BATTERY INSPECTION AND CHARGING
Before removing the battery charger lead
G
clips from the battery terminals, be sure
to turn off the battery charger.
Make sure the battery charger lead clips
G
are in full contact with the battery termi-
nal and that they are not shorted. A cor-
roded battery charger lead clip may
generate heat in the contact area and a
weak clip spring may cause sparks.
If the battery becomes hot to the touch at
G
any time during the charging process,
disconnect the battery charger and let the
battery cool before reconnecting it. Hot
batteries can explode!
As shown in the following illustration, the
G
open-circuit voltage of an MF battery sta-
bilizes about 30 minutes after charging
has been completed. Therefore, wait
30 minutes after charging is completed
before measuring the open-circuit volt-
age.
