Important: Service agents must comply with all
International, Federal, State, Provincial, and/or
Local laws applicable to the activities it performs
under this bulletin, including but not limited to
handling, deploying, preparing, classifying,
packaging, marking, labeling, and shipping
dangerous goods. In the event of a conflict between
the procedures set forth in this bulletin and the
laws that apply to your dealership, you must follow
those applicable laws.
Effective January 1, 2021, U.S. dealers ONLY are to
refer to the Battery Maintenance Report to identify
vehicles in dealer inventory that require attention. The
Report, located in the Dealer Maxis application on the
GlobalConnect App Center, will conveniently identify
the specific vehicles in your dealer inventory that
require a “Battery Charge” due to a low 12V battery
state of charge, or “Start and Move” to prevent tire flat
spotting and/or brake degradation.

Actions Required
•
It is recommended that dealers monitor the report
only once per week. As a best practice, dealers
should pull a fresh report every Monday morning.
• Vehicles on the report that require a Battery
Charge should be charged using the “Diagnostic
Charge ” mode on the GR8 or the “Diagnostic
Trolley” mode on the Diagnostic Charge Battery
Station (DCBS). For vehicles with two batteries,
each battery should be individually charged.
• The report will also identify vehicles that need to
be started and moved as they have remained
dormant for an extended period and are no longer
transmitting battery state of health information to
GM via Remote Vehicle Diagnostics. Sitting in one
location for long periods can also lead to tire flat
spotting and brake corrosion build up. These
vehicles should be started and moved to prevent
these issues and also to allow GM to connect to
the vehicle so that we can provide proper
recommendations on battery maintenance.
After taking action on any particular vehicle noted on
the Battery Maintenance Report, it may take up to 5
days for the vehicle to be removed from the Report.
Refer to Service Bulletin # 21-NA-043 for
requirements on properly maintaining vehicles in
dealer inventory.

Battery Maintenance Report Frequently
Asked Questions (FAQs)
Q1: Why do the Dealers need to do this? Doesn’t
the PDI process take care of this?
A1: Effective January 1, 2021, we made the following
PDI changes for 12 Volt Battery Maintenance:
• Eliminated initial PDI battery check and charge
• Eliminated battery charge every 30 days on New
Vehicle Inventory
• Eliminated final PDI battery check and charge just
prior to delivery
Note: There was no reduction to PDI labor time
allowances.
Note: GM announced a temporary process involving
HUMMER EVs that requires a charge and test during
the final PDI inspection. Please follow PIT5919 while
the temporary process is required.
Q2: How can Dealers access the Battery
Maintenance Report?
A2: Dealers may access the Battery Maintenance
Report by:
1. Clicking on “Maxis for Dealers” App link in the
GlobalConnect App Center
2. From the Dealer Maxis home page, click on the
“Battery Maintenance” tile
Note: If you find you do not have access, please
see your dealer Partner Security Coordinator (PSC).
Q3: What VINs appear on the Maintenance report?
A3: Vehicles that meet the following criteria:
• U.S Pre-sale inventory
• Less than 500 miles
• AT&T cellular connection
• OnStar full services not activated
• Vehicles Delivered to Dealer or ship-to location
Q4: What does the Required Action “Battery
Charge” mean on the report?
A4: This action alert indicates the vehicle battery
requires charging due to its low state of charge (SOC).
SOC refers to the battery capacity not the voltage. If the
battery SOC is less than 50% of its full capacity, the
VIN will appear on the report.
All vehicles showing this required action must be
charged using the “Diagnostic Charge ” mode on the
GR8 or the “Diagnostic Trolley” mode on the Diagnostic
Charge Battery Station (DCBS) to sufficiently charge
the battery.
Note: DO NOT use the PDI mode to charge. This
mode will only charge for 20 minutes and does not
provide enough charge.
Q5: After I charge the battery, when will the VIN be
removed from the report?
A5: Once battery SOC is above 65%, the VIN will
come off report within 5 days.
Page 3
Q6: What Voltage is 50% State of Charge?
A6: State of Charge is the measure of a battery’s
capacity not the voltage. As capacity reduces the
voltage will lower. Approximately 12.1 Volts at 50%
SOC. Battery SOC percentage is dependent on
temperature so reference Battery Charging in SI (Doc
ID: 5696248).
Q7: What if my vehicle has two 12V batteries?
A7: Stop/Start vehicles, Medium Duty, Heavy Duty
trucks often have the batteries in parallel, so only one
state of charge reading is reported. Each one should be
individually tested with a diagnostic charger. For Police
vehicles, only the main 12V battery is monitored with
the battery sensor and not the Auxiliary battery. Both
should be checked when “Charge Battery” is displayed
on the report.
Q8: What does Required Action “Start and Move
Vehicle” mean on the report?
A8: This alert indicates the vehicle has not been moved
for over 30 days. Dealers must start and move the
vehicle to prevent tire flat spotting and/or brake
corrosion build up.
Q9: How far do I need to drive a vehicle that needs a
“Start and Move”?
A9: Moving the vehicle 8 feet forward and 8 feet back
will be sufficient.
Q10: If a vehicle alerts for needing a charge, can I
just start the vehicle and let it run for a while?
A10: No. Vehicles on the report have reached the
caution threshold and our testing shows that they
require the type of charging provided using the
“Diagnostic Charge” mode on the GR8 or Diagnostic
Trolley” mode on the Diagnostic Charge Battery
Station (DCBS).
Note: Just starting and running the vehicle or
charging in “PDI Mode” will not be effective.
Q11: If our GR8 or DCBS is down, can I use a
different battery charger?
A11: A different charger may or may not provide
enough charge to remove the battery from the report,
depending upon the model/time charged etc. Dealers
should have equipment repaired as soon as possible.
See Service Policies and Procedures for additional
information.
Note: PDI Mode charges will not be effective. It will
only charge for 20 minutes.
Q12: How often does the Battery Maintenance
Report update?
A12: The report updates every day, but each vehicle
sends updates once every 5 days. Therefore, after a
vehicle is charged by your dealership, it may take UP
TO 5 calendar DAYS for the vehicle to be removed from
the report.
Q13: What happens if dealer action is not taken
within 10 calendar days?
A13: It has been determined that battery damage can
occur if it is left under 50% State of Charge for longer
than 10 days. Should battery replacement become
necessary because of lack of action as communicated
in the Battery Maintenance Report, this would be at the
dealership’s expense.

Q14: Does OnStar need to be activated for GM to
receive battery information from the vehicle?
A14: No, full OnStar Activation will disable SOC
monitoring and the VIN from the report.
Q15: How should an Electric Vehicle (EV) be
charged?
A15: If an Electric Vehicle (EV) appears on your Battery
Maintenance Report, GM recommends charging the
high voltage (HV) battery with a Level 2 or DC Fast
charger. The high voltage system is designed to
maintain the 12V battery state of charge.
Q16: If charging the HV battery does not
successfully charge the 12V battery, and therefore
the technician needs to charge the 12V battery,
does that have to be performed ONLY by a fully EV
trained technician?
A16: Yes. The technician performing a charge and test
on the 12V battery must have completed all required
EV training. Technician should refer to Refer to
Document ID: 5840812 “Battery Negative Cable
Disconnection and Connection ” in SI before
disconnecting the 12V battery.
Q17: Once a vehicle is added as a Dealer Demo or
loaner, will it come off the report?
A17: Vehicles that have activated OnStar or have
greater than 500 miles will be automatically removed
from the report.
Q18: Are vehicles that are in transit to the
dealership on the report?
A18: No, only vehicles that have been delivered to the
dealer or a designated ship-to location will appear on
the Maintenance Report.
Q19: Are vehicles located at an Upfitter on the
report?
A19: Bailment units ordered as part of an upfitter fleet
WILL NOT be on the report; however, vehicles ordered
by the dealer with an upfitter identified as the ship-to
location WILL BE on the report. It is the Dealers
responsibility to contact the upfitter if the vehicle is on
the report and needs action.
Q20: What happens if a vehicle sale does not go
through, and a vehicle is returned to inventory?
A20: No action is required if a returned back to the
dealer’s stock within 48 hours after the retail sale.
Note: Loaners/demo are not categorized as return
to stock vehicles.
Q21: Why do some vehicles show on up on the
Regional Report, but not on Dealer Maxis?
A21: The Regional report is a snapshot in time and the
resulting picture can be different than the Dealer Maxis
report if they were snapshots taken at varying intervals.

Vehicles can be sold, pinged again, traded or have
been started and moved between the times the two
snapshots are taken and reported. Since the Regional
data is run early Monday morning. We recommend
dealers pull their Maxis report each Monday to
minimize the possibility of different snapshots.
Q22: Who do I contact if there’s an issue with the
data displayed in the Battery Maintenance Report?
A22: Dealers should contact their District Service
Manager if they feel there is an issue with the data in
the report.
Q23: I charged the vehicle and it’s still on the report
after 5 days. Why?
A23: There are a few possibilities:
• The VIN did not go above 65% battery state of
charge (SOC).
• Vehicle did not have cellular connection will retry
to communicate again in 5 calender days.
• Vehicle may be in deep sleep state and requires
the ignition to be cycled.
• Vehicle once had OnStar active and now it is
disabled.
• Terms and Conditions were rejected on the
infotainment center.
Q24: What happens if a battery fails testing after a
charge?
A24: If vehicle requiring charging per Battery
Maintenance Report fails the initial test, retain the test
printout and RETEST, again using the required
“Diagnostic Charge” (GR8) or (DCBS) process.
Labor to perform the retest is covered as follows:
1. If the battery PASSES the retest, the vehicle can
be returned to inventory. Dealers may claim a
ZREG Transaction Type for performing the retest
using Labor Code 0600284 (Pre-Sale Charge and
Test). The allowable allowance mirrors the
vehicle’s applicable published Base Labor Time for
Labor Code 4041512 (Battery Charging and
Testing). Published Add Times are ineligible. The
transaction must be routed to the Warranty Support
Center with a copy of BOTH the initial test and the
retest result printouts attached to the transaction.
2. If the battery FAILS the retest, replace the battery
and submit a ZREG warranty claim using the
applicable labor operation and published
allowance per the Labor Time Guide (labor for
testing is included in the published allowance for
battery replacement). Attach BOTH copies of the
test result to the transaction. Enter the 2nd code
(obtained after retest) in the Battery Tester Code
field of the warranty transaction.
GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
