6. Micro-ohm readings should be taken across every
connection. (Refer to Fig. 6-2, pg. 6.) If any reading
differs by more than 20%, retorque the connection
to 100 ± 5 inch-pounds. If the reading remains high,
clean contact surfaces according to Step 2 under
Connector Assembly.
MAINTENANCE
Always wear eye protection when working on or near
batteries. Keep sparks and open flames away from
batteries at all times.
Annual Inspection
1. Conduct a visual inspection of the battery.
2. Check the battery terminal voltage.
3. Check the charger voltage.
4. Check the individual cell voltages. Cells should be
within ± .05 volts of float voltage.
5. Check the ambient temperatures.
6. Check all interunit and terminal connections. Micro-
ohm readings should be taken during this inspec-
tion. If any reading differs by more than 20% from
the initial reading taken, retorque the connection to
100 ± 5 inch-pounds. Recheck the micro-ohm read-
ing. If the reading remains high, clean the contact
surfaces according to Step 2 under Connector
Assembly.
Battery Cleaning
Battery modules and covers should be cleaned with
clear water or a mixture of baking soda and water.
Never use solvents to clean the battery.
Capacity Testing
Capacity tests should not be run unless the batteries
operation is questionable. Do not discharge the batter-
ies beyond the specified final voltage. Record all find-
ings.
Should it be determined that any individual cell(s)
need to be replaced, contact your nearest Unigy II
Agent or East Penn Service Center.
CELL REMOVAL PROCEDURE
1. Before removing cells, review safety procedures
on page 2 of this manual. Contact East Penn
Manufacturing Company, Inc. with specific questions
or concerns.
2. Refer to Fig. 8-1 through 8-4 (pg. 7) for specific
