12 VOLT BATTERY STORAGE AND MAINTENANCE
FOR NEW VEHICLES IN RETAILER INVENTORY
This bulletin has been amended. See AMENDMENT HISTORY on the last page.
Please discard previous versions of this bulletin.

APPLIED VEHICLES:

All new (unsold) Infiniti vehicles in retailer inventory

SERVICE INFORMATION
Design and process changes have been made to improve battery voltage at retailer receipt. Our goal is to
deliver vehicles to clients with a 12 volt battery in excellent condition. Proper retailer storage and maintenance
of vehicle 12 volt batteries is essential for good battery operating life and client satisfaction.
Retailers are responsible for maintaining vehicles in their inventory. The 12 volt battery in new vehicles in
retailer inventory should always be kept at a healthy state of charge. This will prevent excessive discharge
during storage and keep vehicles ready for delivery to clients at any time.
If 12 volt batteries in new vehicles are allowed to discharge for a prolonged period of time, battery life may be
drastically reduced. This condition may lead to premature battery replacement and client dissatisfaction.

IMPORTANT:


CPX-900 is now an accepted testing tool to use along with or in place of the DSS-5000.

 CPX-900 operating instructions are found at: https://nissancpx900.midtronics.com/


DSS-5000 operating instructions are found at: https://nissandss5000.midtronics.com/



DCA-8000 is now a required testing tool to be used for all warranty charge sessions. The
DCA-8000 is also a more efficient charger than previously available and will charge any available
12 volt lead acid battery safely and accurately as long as all precautions and inputs are made correctly.
The DCA-8000 operating instructions are found at: https://nissandca8000.midtronics.com/

Infiniti Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are properly trained
individuals who have the equipment, tools, safety instruction, and know-how to do a job properly and safely. NOTE: If you believe that
a described condition may apply to a particular vehicle, DO NOT assume that it does. See your Infiniti retailer to determine if this
applies to your vehicle.

Required PDI Check-in (PDI Battery Test) Process Flow Overview
Upon receipt of new vehicles, retailers are responsible for performing a CHECK-IN test on the 12 volt battery
within 72 hours of delivery, or upon receipt from a retailer trade.


A CHECK-IN test must be performed with the DSS-5000 or CPX-900.



The retailer is responsible for keeping detailed records of battery maintenance, including the
CHECK-IN test results, with the PDI information.



Prior to beginning the CHECK-IN test, please ensure the following conditions are met:
o The battery is above 0°C (32°F).
o The battery posts are clean and secure.
o For at least 5 minutes, the vehicle's engine has been OFF and the battery has not been charged.
 If a battery is discharged or rapidly charged within a close time to battery testing, it can cause a
polarization/stratification of the battery electrolyte. This will cause inaccurate testing of the
battery and could result in an improper replacement decision from the testing tools. In the case
of the DCA-8000, it will likely generate a warning, delaying testing due to the stratification of the
electrolyte.



For additional information regarding testing procedures, refer to the 12-volt Battery Maintenance and
Diagnosis eLearning course available on INFINITI University Online in the INFINITI Technician Online
Courses category.

Replace the battery
 Refer to the ESM for proper torque
specification when reconnecting the
battery cables
 Use Replace Battery Code for warranty
claim and attach test strip to repair order

Perform battery check using
Inventory Test with DSS-5000 or
CPX-900 every 30 days

Perform System Test with
DSS-5000, CPX-900, or DCA-8000 to confirm
charging and starting
systems are operating correctly

If a “charge and retest” or
“test with DCA” result is given,
charge battery using DCA-8000.
Once testing and charging are
complete, confirm the vehicle is
returned to storage condition with
the extended storage switch
pulled out and the negative
battery cable disconnected from
the battery post

Keep the test strip with the vehicle records and
include it with the PDI information

HINT: The time allowance for the battery CHECK-IN (and possible subsequent diagnostic charge) test(s) is
included in the total PDI flat rate time and will be reimbursed as part of the current PDI payment, even though
the remainder of PDI activities may take place at a later time.

Required 12 Volt Battery Maintenance for Retailer’s New Vehicle Inventory
For unsold vehicles:


Maintain vehicles with transit mode and extended storage switch in inventory-condition (storage-mode)
to reduce battery drain.



If a vehicle is being stored on the retailer lot, routinely check the battery State Of Charge (SOC) and
charge the battery as needed using the DCA-8000 every 30 days.
o For display vehicles, be sure to check every other day and charge as needed to avoid low SOC
conditions.

IMPORTANT:
o Retailers should discontinue the practice of starting an engine to see if the battery is
“good.” Batteries may still start an engine even with a low SOC and the battery may be further
damaged if the battery is not recharged after starting. Battery checks should always be
performed with the DSS-5000, CPX-900, or DCA-8000.
o Idling the engine to charge the battery is NOT recommended for most vehicles since the
effectiveness is highly dependent on the vehicle storage conditions such as temperature, vehicle
type, initial SOC, and alternator type.
 For 2022 and newer QX60, idle charging can be used when properly prepared.


Ensure the vehicle is in shipping mode by confirming the position of the extended storage
switch. The position of the extended storage switch should not be changed while the
ignition is ON.

o Prior to charging any battery, determine if it is a standard flooded battery, an Enhanced Flooded
Battery (EFB), or an Absorbent Glass Mat battery (AGM). Refer to pages 10-13.
o Testing a “cold” battery (below freezing) may result in incorrect test decisions. If a “REPLACE”
decision is reached yet the vehicle starts without hesitation, perform a diagnostic charge with
DCA-8000. The DCA-8000 can more accurately determine the battery temperature and will
generate a warning if the battery is too cold to accurately test. It can warm the battery directly
through a discharge/charge micro-cycle to more quickly test a battery too cold for normal testing.
Allow the battery sufficient time for resting before attempting to retest from this condition,
preferably once the battery has risen above 0°C (32°F).



The 15 digit battery test code generated by the DCA-8000 must be submitted with every PDI battery
replacement claim.



“Good battery” codes and test strips from “CHECK-IN” or “Systems Test” should be kept with the
vehicle records and included with the PDI information.



DO NOT SUBMIT “Good Battery” test codes with warranty claims.



Refer to warranty policy bulletin WPB/11-023 for additional information regarding battery claim policy
procedures.

ITB09-015O

Enhanced Flooded Batteries (EFB)
An increasing number of Infiniti vehicles are being equipped with an Enhanced Flooded Battery (EFB). It is
important to verify battery type to ensure the correct tests are performed and no damage occurs to the battery
or other vehicle systems.
To avoid the risk of death, severe personal injury or damage to the vehicle, do not use a battery charger that
does not have an EFB specific charging profile. Failure to do so may cause battery acid to leak onto the vehicle
and/or flammable gases to combust while charging.


EFBs require an equalization charge to address electrolyte stratification that can occur in this type of
battery.
o If a vehicle has the factory equipped 12 volt battery: The Midtronics battery testing software will
automatically perform the correct charge. The type of factory equipped battery is determined by
entering the vehicle information into the tester.
o If the vehicle’s 12 volt battery has been replaced: It is important to determine if the battery is an
EFB or not.
 Check the battery for a designation, such as those shown in Figure 9 through Figure 11.
 If an EFB battery type cannot be determined by markings on the battery, contact the battery
supplier.

Figure 9


EFBs also come in ranges such as Q-85 and Q-95.

Figure 10

10/14

ITB09-015O

Figure 11
HINT:


Charging requirements for EFBs are different from standard flooded batteries.



ONLY testers with an EFB charging profile will properly charge an EFB that has a low SOC.



The equalization charge for EFBs may take up to 5 hours.



Failure to properly identify an EFB could result in inaccurate test results (for example, calling a good
battery bad).

To avoid the risk of death, severe personal injury or property damage, remove the battery from the vehicle and
place it in a well-ventilated area before starting the charging cycle. Charging the battery while in the vehicle
may cause battery acid to leak onto the vehicle and/or flammable gases to combust while charging.

To avoid the risk of damage to the battery, do not charge an EFB battery using a non-EFB diagnostic charge.

11/14

ITB09-015O

Absorbent Glass Mat (AGM) Batteries
An increasing number of service batteries are now sourced as Absorbent Glass Mat (AGM) batteries. It is
important to verify battery type to ensure the correct tests are performed and no damage occurs to the battery
or other vehicle systems.
To avoid the risk of death, severe personal injury or damage to the vehicle, do not use a battery charger that
does not have an AGM specific charging profile. Failure to do so may cause battery acid to leak onto the
vehicle and/or flammable gases to combust while charging.


AGM batteries require a specialized slow charge for correct SOC recovery without battery damage.



It is important to determine if the battery is an AGM or not.
o Check the battery for a designation, such as those shown in Figure 12 through Figure 14.
o If the correct battery type cannot be determined by markings on the battery, contact the battery
supplier.

Figure 14

To avoid the risk of death, severe personal injury or property damage, remove the battery from the vehicle and
place it in a well-ventilated area before starting the charging cycle. Charging the battery while in the vehicle
may cause battery acid to leak onto the vehicle and/or flammable gases to combust while charging.

To avoid the risk of damage to the battery, do not charge an AGM battery using a non-AGM diagnostic charge.
