NOTE: The GR8 Battery Management System Q85/T110 softwar~ is_p_urrently.under,deve!opment. l.Jse.the
GR8 Battery Management System, Manual Mode Battery Charging procedure in this bulletin to charge
the Q85/T110 battery at this time. This bulletin will be reviSed when the new software is available.

Q85/T110 BATTERY MAINTENANCE
1. Maintain battery charge during vehicle storage.
Charge the battery regularly even though there's no electrical load applied.
If battery is left discharged for long periods, battery failure may occur.
2. Maintain battery charge during parts inventory.
Charge the battery regularly during parts stock.
If battery is left discharged for long periods, battery failure may occur.

Q85/T110 BATTERY INSPECTION
1. Voltage measurement.
Battery voltage can only be measured on a battery that has not been recently charged.
If the battery was recently charged, wait 6 hours or more before checking the battery voltage.
a. Is the battery voltage 12.4 volts or higher?
Yes - The battery is charged.
No- Proceed to Q85/T110 BATTERY CHARGING.
2. Specific gravity measurement.
This is the p'referred method for battery inspection because battery condition can be ascertained.
a. Mix the electrolyte solution on all 6 cells by using a siphon to suction the electrolyte from the battery
and then put it back in.

2. Connect the current sensor connector (A) to the
current sensor (B).

Q85/T110 OPERATION REQUIRED AFTER BATTERY REPLACEMENT
NOTE:
If the battery charge/discharge flow (number of times battery can operate) exceeds the specification, a OTC is recorded and the master warning light turns on. If the battery charge/discharge flow
(number of times battery can operate) exceeds the specification, replace the battery with a new
one.
When replacing the battery, perform the following procedure. When replacing the PCM simultaneously, perform the PCM configuration first.
