ELEC
BATTERY (EF7000E/EF7200E/EF7200DE)
NOTICE
9 Do not use a high-rate battery charger
since it forces a high-amperage current
into the battery quickly and can cause
battery overheating and battery plate
damage.
9 If it is impossible to regulate the charg-
ing current on the battery charger, be
careful not to overcharge the battery.
9 When charging a battery, be sure to
remove it from the generator. (If charging
has to be done with the battery mounted
on the generator, disconnect the nega-
tive battery lead from the battery termi-
nal.)
9 To reduce the chance of sparks, do not
plug in the battery charger until the bat-
tery charger leads are connected to the
battery.
9 Before removing the battery charger lead
clips from the battery terminals, be sure
to turn off the battery charger.
9 Make sure the battery charger lead clips
are in full contact with the battery termi-
nal and that they are not shorted. A cor-
roded battery charger lead clip may gen-
erate heat in the contact area and a weak
clip spring may cause sparks.
9 If the battery becomes hot to the touch
at any time during the charging process,
disconnect the battery charger and let
the battery cool before reconnecting it.
Hot batteries can explode!
9 As shown in the following illustration,
the open-circuit voltage of a VRLA (Valve
Regulated Lead Acid) battery stabilizes
about 30 minutes after charging has
been completed. Therefore, wait 30 min-
utes after charging is completed before
measuring the open-circuit voltage.
