CHECK
1.
General
This section contains battery functional tests and maintenance requirements. Test
procedures are written in a step-by-step format.
NOTE:
2.
The ( ) part identification numbers herein are IPL, Figure 1 item numbers.
Scheduled Maintenance
A.
Regular Check: At 1000 hours or 6 months, perform the following:
NOTE:
These periods are given as an indication; modify in accordance
with operational experience.
NOTE:
Maintenance checks may be combined if operating hours do not
meet times listed.
(1)
Discharge the battery at 50 A down to a voltage of 11 V at the battery
terminals.
(a)
Measure and record the time from the start of discharge to the
moment 11 V is reached.
(2)
Continue with a residual discharge by connecting a resistor of
approximately 1 W (3 W) across each cell. (Resistors with clips
attached to their leads can be easily attached to the cell terminals.)
(3)
Leave resistors in place overnight.
(4)
Remove all the resistors.
(5)
Charge the battery (Section 3).
(6)
Adjust the electrolyte level in the cells (Section 3).
(7)
Perform a capacity check (Section 3.C).
(a)
Discharge the battery again at 50 A.
(b)
Measure the terminal voltage of each cell.
24-34-04
PAGE 501
Dec 12/97
SAFT AMERICA INC.
COMPONENT MAINTENANCE MANUAL
43B050LB01
(c)
(8)
Record the time that is needed for the first cell to reach 1.0 V
and the battery terminal voltage to reach 11.0 V.
Conclusions to be drawn from the above tests:
(a)
(b)
The battery is functioning properly if:
1
The first discharge required more than 30 minutes.
2
The second discharge required at least 51 minutes for
the first cell to reach 1.0 V.
3
Each individual cell voltage during the last 15 minutes of
charge at 5.0 A is at least 1.5 V (accuracy ±0.5%)
4
The quantity of distilled water added to each cell is
approximately equal to or less than 25 cm3 (1.55 in3).
5
If the duration of the first discharge is less than 30
minutes but the second discharge time is correct (at least
51 min) it may be concluded that the battery is in good
condition but was not fully charged when removed from
the aircraft (this may be due to insufficient recharge on
board and/or discharge resulting from unexpected use of
the battery after landing.)
The battery must be given a General Overhaul if:
1
The duration of the second discharge is less than 51
minutes or if any cell has a voltage of less than 1 volt or
reversed polarity before 51 minutes of discharge.
2
Individual cell voltages measured during the last 15
minutes of charge at 5.0 A are less than 1.50 V.
3
One or several cells required considerably (10-25%)
more or less distilled water than the other cells.
NOTE:
The consumption of water by a Saft nickelcadmium cell is proportional to the
overcharge that it has received.
24-34-04
PAGE 502
Dec 12/97
SAFT AMERICA INC.
COMPONENT MAINTENANCE MANUAL
43B050LB01
NOTE:
C.
The fact that one or more cells of the same
battery consume noticeably more or less
water than other indicates a defect:
a
High consumption is generally caused by leakage.
b
Low consumption is caused by separator damage.
c
Consumption is considered to be abnormal when it
is 10-25% more or less than average.
(9)
Charge the battery (Section 3).
(10)
Return battery to service.
General Overhaul
In addition to the electrical tests described in the Regular Check, the General
Overhaul includes a systematic disassembly and cleaning of all components
of the battery. It must be carried out at 2000 hours or at least once a year.
(1)
Disassemble the battery (DISASSEMBLY).
(2)
Clean the battery (CLEANING).
(3)
Test the battery
(a)
Box:
1
(b)
Nuts, links, and spring washers:
1
(c)
Straighten the box sides and flatten out any minor dents
with a hard rubber mallet.
Discard and replace any corroded or damaged
components.
Spacers:
1
Discard and replace all defective components.

3.
Ensure that the connector is in good condition, both inner
and outer surfaces. Replace if the connector contacts
show any signs of corrosion, burning, or arcing.
Battery Charging, Electrolyte Level Adjustment and Capacity Test
NOTE:
A.
The success of these tests depends very much upon keeping the
battery cool. High temperature, during a discharge procedure and
particularly during a charge procedure, will result not only in poor
equalization but in a shortened life for the battery. For best results, the
ambient temperature must be 60°F to 80°F (15.6° C to 26.7°C) . The
battery temperature at the start of a charge procedure must be at room
temperature 60°F to 80°F (15.6°C to 26.7°C). A 12 hour rest is
required following a discharge procedure. There is not a required rest
period between completion of a charge and the start of dicharge
procedures.
Charge
CAUTION:
ATTEMPTING TO CHARGE BATTERIES WITH LOW
ELECTROLYTE LEVELS IN ANY CELL MAY CAUSE DAMAGE
TO THAT CELL.
(1)
Prior to charging the battery, remove the cover (50) and loosen (do not
remove) all vent valves (250). Ensure that the shorting spring has
been removed from the connector adapter (130).
(2)
Charge the battery using one of the procedures that follow:
NOTE:
(a)
Check individual cell voltages at the beginning of the
charge. If any cell indicates an immediate voltage rise
above 1.50 volts, add about 10 cm3 of distilled or
demineralized water through the vent valve opening of
that cell.
Charge battery at 5.0 A until the voltage reaches 16.5 V. Then,
continue charging battery at the 5.0 A rate for 4 additional
hours. The total charge time must be at least 14 hours, but not
more than 16 hours.
24-34-04
PAGE 504
Dec 12/97
SAFT AMERICA INC.

43B050LB01
(b)
Charge the battery at 25 A for at least 2 hours but not more than
2 hours and 30 minutes until the battery voltage has reached

Electrolyte Level Adjustment
WARNING: USE CARE NOT TO TILT CELLS WHILE VENT VALVES ARE
LOOSENED OR REMOVED; CONTACT OF ELECTROLYTE
WITH SKIN CAN CAUSE SEVERE BURNS.
CAUTION:
(1)
BATTERY MUST BE FULLY CHARGED BEFORE ADJUSTING
ELECTROLYTE LEVEL.
To perform the electrolyte leveling procedure, the indicator level
assembly (P/N 21961-000) included in the battery maintenance kit
(P/N 23249-000) must be modified per instructions below .
(a)
Measure 1 3/8 inches (34.93 mm) from the tip of the tube and
make a mark.
(b)
Drill a 3/32 inch (2.38 mm) hole through one side of the tube at
the mark as shown in Figure 508.
(2)
Before the adjustment of the electrolyte level, remove the vent valves
(250) with the special, plastic vent valve wrench (20) supplied with the
unit. Immerse the valves (250) and their o-rings (260) in distilled or
deionized water, and let them soak to dissolve any salts. Cover the
cells (240) with a clean damp cloth to prevent entry of foreign matter.
(3)
Remove the cloth only while checking electrolyte level. Check the
liquid level in the cell (240) by inserting the modified indicator level
(P/N 21961-000) into the cell opening until the tip of the tube rests on
the bottom of the plastic baffle inside the cell (Figure 508). Squeeze
the ball and check for any liquid in the indicator level. If the liquid level
is too low, the indicator level will remain empty, indicating that the hole
in the tube did not reach the liquid in the cell. Any excess liquid in the
cell will be drawn into the indicator level until the electrolyte is level with
the hole in the tube. This is the correct level for the electrolyte.
(4)
If the electrolyte is low, use the following procedure to fill the cell
(240) to the correct level:
24-34-04

SAFT AMERICA INC.
COMPONENT MAINTENANCE MANUAL
43B050LB01
NOTE:
Use only distilled or demineralized water. The
3
quantity (in cm ) of distilled water required to fill
the cell (240) to the correct level will serve as an
approximate guide to the amount required for the
remaining cells (240). The water in each cell
(240), however, must be adjusted individually to
the correct level.
(a)
Draw an amount of the distilled water into the indicator level and
inject it into the cell (240).
(b)
With the tip of the indicator level resting on the bottom of the
baffle as shown in Figure 508, fully squeeze the bulb of the
indicator level and release.
(c)
If the indicator level remains empty, repeat steps (a) and (b) to
achieve the correct level.
(d)
At the point in step (b) when some excess liquid is drawn into
the indicator level, the correct level for that cell has been
reached. Expel the excess liquid into a container for later
disposal.

Initial Discharge (Capacity Test)
The purpose of this discharge procedure is to determine the initial capacity of
a new/stored battery or the electrical characteristics of a battery when it is
removed from the aircraft; either for routine maintenance or for investigation
of a malfunction. The results of this initial discharge will determine the steps
that should be taken.
(1)
Discharge the battery at one of the current rates shown in Figure 509
until the battery reaches 11 V.
NOTE:
(2)
Monitor individual cell (240) voltages periodically during the discharge,
and record the time at which the first cell (240) reaches 1.0 V. Stop
the discharge when the battery voltage reaches 11 V.
NOTE:
(3)
It is important that the discharge current be continually
maintained at the selected value, and that the time of
discharge be measured accurately.
If a cell (240) goes to zero volts or reverses polarity
during the battery discharge, short out the cell's (240)
terminals for the remainder of the discharge.
If the "weakest" cell (240) fails to meet the required minimum
discharge time shown in Figure 509, proceed to Special Tests.

(a)
Continue to discharge the battery, and as each cell (240)
reaches 1.0 V, connect a 1.0 W (3.0 watt minimum) resistor
across its terminals. Leave the resistors in place for 16 hours to
allow the cells (240) to completely discharge and the battery to
cool.
NOTE:
(b)
4.
Attach the resistors with alligator clips to make a
firm connection.
Continue to discharge the battery, and as the battery reaches
10 V, insert a shorting clip between the main terminals. Leave
this clip on for 16 hours to allow the battery to completely
discharge and cool.
Testing
A.
Test Conditions
Conduct all tests with the battery temperature at 60°F to 80°F
(15.6°C to 26.7°C).
B.
Test Equipment
Refer to Table 901(B) for test equipment recommendations.
C.
Connector and Sensor Assembly
(1)
Identification of the Connector and Sensor Assembly
Prior to performing testing on the Connector and Sensor Assembly,
you must determine which style sensor is installed in the battery. The
identification can be accomplished in two ways:
(a)
Visually
NOTE:
1
The connector and sensor assembly must be
removed to be visible for this identification.
When viewing the connector in its normal mounting
position, the original style connector and sensor
assembly (190) (GE P/N 139C2495ABG1), will have two
wires exiting the potting compound on top of the sensor
mounting bracket.
24-34-04
PAGE 510
Aug 17/01
SAFT AMERICA INC.
COMPONENT MAINTENANCE MANUAL
43B050LB01
2
(b)
When viewing the connector in its normal mounting
position, the newer style connector and sensor assembly
(7) (P/N 022036-000) will have two wires exiting the
potting compound on the bottom of the sensor mounting
bracket.
Electrically
Using an ohmmeter, connect one lead to pin C of the connector
(7) and the other lead to pin E. The reading on the ohmmeter
will determine which style connector is present.
(2)
1
If the original style sensor is present the ohmmeter
should show open circuit (no movement of the needle
toward zero)
2
If the newer style sensor is present, the ohmmeter should
show a resistance value of 2 kW ±20 W.
Testing of the Connector and Sensor Assembly
(a)
Testing the original style sensor (GE P/N 139C2495ABG1)
This test is designed only to detect open circuit or short circuit
conditions in the connector and sensor assembly. It does not
verify full operation of the sensor. The procedure can be
accomplished without disassembly of the battery. Full operation
of the sensor can be verified by completing the testing
procedure in 4.C.(2)(c).
NOTE:
If the sensor fails any part of the following tests,
the sensor must be replaced with an original SAFT
replacement (P/N 022036-000).
NOTE:
The voltmeter range is to be between 1,000 ohms
and 20 kW per volt.
1
Measure and note the battery voltage. The battery
voltage must be at least 13 volts to perform this test.
2
Connect pin E of the sensor connector to the negative
terminal of the battery using a jumper cable.
24-34-04
PAGE 511
June 15/98
SAFT AMERICA INC.
COMPONENT MAINTENANCE MANUAL
43B050LB01
(b)
3
Connect pin C of the sensor connector to the negative
terminal of the voltmeter.
4
Connect the positive terminal of the voltmeter to the
positive terminal of the battery. Note the reading on the
voltmeter.
5
If the voltmeter reading in step 4 is greater than 1 volt,
the circuit is not open. If the difference between the
voltage reading in step 1 and the voltage reading in step
4 is greater than 1 volt, a short circuit does not exist.
6
Using an ohmmeter, measure the resistance between pin
G of the sensor connector and the positive terminal of the
battery. The reading should be 1 kW ±10%.
Testing of the new style Connector and Sensor Assembly
(P/N 022036-000)
This test is designed to check the components of the Connector
and Temperature Assembly. This procedure can be
accomplished without disassembly of the battery. Full operation
of the sensor can be verified by the completion of the testing
procedures in 4.C.(2)(c).
(c)
1
Measure the resistance between Pin C of the connector
and Pin E. The resistance will be 2 kW +20 ohms.
2
Measure the resistance between Pin G of the connector
and the positive terminal of the battery. The resistance
will be 1000 W +100 ohms.
3
Measure the resistance between Pin C of the connector
assembly and the battery case, then between Pin E of
the sensor connector and the battery case. Each of
these readings should be greater than 20 MW.
Low temperature testing of the Connector and Sensor Assembly
This test should be used for both the original style sensor and
the newer style sensor. Disassembly of the battery and removal
of the Connector and Sensor Assembly is required for this
procedure.

Vent Valve Pressure Test
Check the operation of the vent valves as follows:
E.
(1)
Prepare a fixture from PVC pipe and fittings with an end adapter
configured on the inside to match the vent valve locking mechanism.
(2)
Affix the valve (250) with its o-ring (260) into the adapter end of the
pressure test fixture.
(3)
Attach the fixture to a compressed air line through an adjustable
pressure-reducing valve.
(4)
Immerse valve (250) and end of fixture in water, and slowly raise the
pressure. Make sure the valve opens between 2 to 10 psi (0.14 to 0.7
bar).
(5)
Reuse only those vent valves (250) found to open in the 2 to 10 psi
(.014 to 0.7 bar) range. Re-soak vent valves that do not open at 10 psi
(0.7 bar) until they do open (refer to Cleaning). Discard vent relief
valves (250) which are not gas tight at low pressure.
Battery Insulation Resistance
NOTE:
A BREAKDOWN IN ELECTRICAL INSULATION BETWEEN
THE CELLS AND THE BATTERY CASE (10) WILL RESULT IN
“LEAKAGE” CURRENT, WHICH OVER TIME WILL
DISCHARGE THE BATTERY.
(1)
Set up the analog multi-meter (volt, ohm, amp) and meter leads for a
measurement of 250 mA.
(2)
Connect the negative lead from the meter to the battery container.
(3)
Touch the positive lead from the meter to the positive terminal of the
battery and then to the positive terminal of each cell (240).
(4)
If while performing the above, there is any deflection of the needle
from zero the insulation should be considered defective. Disassemble
and clean the battery (DISASSEMBLE and CLEANING).
(5)
If, after cleaning the battery and assuring that everything is dry, a
leakage current is still indicated by a deflection of the needle, one or
more cells (240) is defective. Isolate and replace the defective cell(s)
(240) (DISASSEMBLY, ASSEMBLY).

(6)
F.
5.
As an alternative to the above test: after completely reassembling the
battery, measure the insulation resistance between the block of cells
(240) and the metal box (10). The value measured must be at least
10 MW under 250 V continuous using an ohmmeter.
Polarization Test
(1)
Charge the battery at 5.0 A for 1.5 hour.
(2)
Leave the battery in open circuit condition for 1 hour.
(3)
Measure the open voltage of each cell (240).
(a)
If the cell (240) open voltage is 0 V or reversed carry out a
special test and proceed to repair.
(b)
If every cell (240) presents an open voltage above 0 V, charge
the battery.
Special Testing
These procedures are to be followed if deemed necessary per Fig 506.
A.
Discharge the battery per one of the methods in Figure 509.
NOTE:
It is not necessary to monitor time.
B.
Perform the residual discharge procedure described in Section 3.C.
C.
Charge the battery using one of the methods in Figure 505.
D.
Perform an additional overcharge period of 4 hours at 0.1C1A (5.0 amps).
During this overcharge procedure, measure each cell voltage every 15-20
minutes making notation of each reading. Mark for replacement any cell that
expresses a drop in voltage during this overcharge procedure, or any cell with
an end of charge voltage less than 1.5 V.
NOTE:
A drop in voltage during overcharge indicates a defect in the
gas barrier that is neither recoverable nor repairable. Cells with
this condition must be replaced with factory new cells
(DISASSEMBLY, ASSEMBLY).
NOTE:
If three cells (240) over the life of the battery are replaced it is
best to assume that all of the original cells are in unsatisfactory
condition and should be replaced.
