After the battery system has been on float for
approximately 24 hours, the float current
acceptance should be approximately to .005
amperes or less per rated ampere hour
capacity of the battery string but greater than
zero.
The individual battery float charging voltages
should be within the following range:
• 12 volt batteries 13.3 min. to 14.5 max.
• 10 volt batteries 11.10 min. to 12.1 max.
• 6 volt batteries 6.65 min. to 7.25 max.
• 4 volt batteries 4.43 min. to 4.85 max.
Document the results of these measurement
activities in Section VI, Float Charging Checks,
of the Operational Qualification and Warranty
Registration Checklist, Form #41-7471.
If any special battery monitoring equipment is
to be utilized, it should be installed and
calibrated at this time.
The 12V battery system installation is now
complete and the system is available for
acceptance testing and operational service.

Optional Battery Tests and Checks
While not a requirement of the warranty registration
the following checks are recommended to assure
maximum reliability of the battery system over
time.
1. High rate momentary load test as described in
the document Integrity Testing Form
#41-7264.
While this test does not indicate the actual
capacity of the battery it does indicate it is
functional.
2. Individual battery measurements of resistance/
conductance/impedance as described in the
document Impedance and Conductance
Testing Form #41-7271. Again, while this test
does not indicate the actual capacity of the
battery it does provide base line data from
which changes can be trended over time as
the battery normally deteriorates. This can be
very useful in trouble analysis during the
periodic maintenance activities.
3. Battery performance test as described in the
document Acceptance and Performance
Testing Form #41-7135.
