Table 6 shows that with a 0.8C

inrush current, a 100%
discharged battery can have 80% of its capacity returned
in 60 minutes; doubling the inrush to 1.6C

cuts the time
taken to reach 80% capacity to only 28 minutes.

LOAD TEST PROCEDURE
This procedure should help determine whether the battery
returned by the customer has reached its end of life or simply
needs a full recharge. Depending on the time available one
may choose to perform either the longer load test (Step 4) or
the shorter ½CCA load test (Step 5).
The ½CCA test is quicker but less reliable than the longer test.
This is also the test that is performed when a battery is taken
to an auto store for testing.
1. Measure the open circuit voltage (OCV) of the battery.
Proceed to Step 4 or Step 5 if the OCV is equal to or more
than 12.80V; if not go to Step 2.
2. Charge the battery until fully charged.
3. Unplug the charger and disconnect the battery from the
charger. Let the battery rest for at least 10-12 hours and
measure the OCV. If it is equal to or more than 12.80V
proceed to the next step; otherwise reject the battery.
4. Long Test: Discharge the battery using a resistor or other
suitable load until the voltage drops to 10.00V and record
the time taken to reach this voltage. Let the battery rest
for an hour and repeat Steps 1 through 4. If the time taken
by the battery to drop to 10.00V is longer in the second
discharge than in the first discharge, the battery may be
returned to service after a full recharge; if not the battery
should be rejected as having reached end of life.
5. ½CCA Test: Battery OCV must be at least 12.60V to
proceed with this test. Connect the load tester cables
and the voltage leads of a separate digital voltmeter
(if the tester does not have a built-in digital voltmeter)
to the battery terminals.
6. Adjust the tester load current to load the battery to
half its rated CCA and apply the load for 15 seconds.
Table 7 shows the ½CCA values for all ODYSSEY

battery models. Use Table 8 to adjust the battery end
of test voltage temperature.

7. At the end of 15 seconds note the battery voltage on
the voltmeter and discontinue the test. If the temperature
is 20˚C or warmer the battery voltage should be at or
above 9.60V. If so the battery can be returned to service;
if below 9.60V the battery should be rejected.

BATTERIES IN NO-IDLE
APPLICATIONS
Since these batteries are dual purpose in nature they can
be used for both engine starting and deep cycling
applications. This makes them particularly well suited for
fleets such as police vehicles that would like to power
their computers and communications equipment without
having to idle their engines. Auxiliary power units (APU) on
trucks provide another example of a no-idling application.
