SECTION 3 SPECIAL MAINTENANCE RELATED TO
BATTERY POWERED GENERATORS
This Section only applies to Battery Powered Generators and
must be performed at least once a y ear.
3.1 BATTERY STORAGE CONDITIONS
This generator should be stored at a dry environment around 20
o
C(68
o
F). The
recommended operating temperature is 15
o
Cto30
o
C(59
o
Fto86
o
F).
During normal storage conditions (dry environment at 20
o
C(68
o
F) the internal
resistance of the batteries will cause a discharge rate of 15% per six month
period. Storage above 30
o
C(86
o
F) should be avoided, since it w ill cause
excessive battery voltage loss.
Within the recommended operating temperature and under optimum float
conditions, the batteries service life is expected to exceed 5 years.
The batteries of the Unit are fully charged when delivered from the factory. If the
Unit is going to be stored or has been stored for a period longer than six months,
batteries must be fully charged during eight hours before operation or service
tasks.
If the unit has not been used or it has been stored for six
months, it should be installed and/or energized to prevent
deep discharge of the batteries. A deep discharge will cause
permanent damage to the batteries. Perform the following
Maintenance Tests.
3.2 BATTERY CHARGER TEST AND BATTERY CONDITION TEST
Refer to Section 2.6 “Procedures related to the Battery Powered Generators”
of the Troubleshooting document in the Service Manual and perform all the
indicated procedures to carry out a correct maintenance of the Battery Charger
Board and Batteries.
