Q85/T110 BATTERY 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.

  1. Is the battery voltage 12.4 volts or higher?

 

Q85/T110 BATTERY SPECIFIC GRAVITY MEASUREMENT

Battery condition can be ascertained using this method; however, the preferred method is to use the GR8 Battery Management System. Refer to Q85/T110 BATTERY TEST AND BATTERY CHARGING.

  1. 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. Use a scope type specific gravity battery meter (refractometer) to measure all six cells.
  3. Is the cell with lowest electrolyte specific gravity 1.25 or more?
    • – Yes – The battery is fully charged.
    • – No – Go to next step.
  4. Is the cell with lowest electrolyte specific gravity less than 1.17?
    • – Yes – The battery may be faulty. If however, the battery is under warranty, you must use the Midtronics GR-8 tester as it uses a more accurate method of testing. Proceed to Q85/Q110 BATTERY TEST AND BATTERY CHARGING to accurately test the battery. If the Midtronics GR-8 tester fails the battery it will generate a battery failure code for warranty claim submission.
    • – No – The battery requires charging. Proceed to Q85/T110 BATTERY TEST AND BATTERY CHARGING.

 

Q85/T110 BATTERY INSPECTION WITHOUT GR-8

If the GR8 Battery Management System is not available to test a Q85/T110 battery, refer to MS3 online or Workshop Manual section 01-17.

  1. Would appreciate any information you can share wrt i -eloop battery system in my 2015 Mazda 6 SkyActiv. This is crazy that there is no English words on the battery, can’t seem to find a replacement or anyone who can explain the Display: Battery Management System Inspection Required.

    Car struggles to start but does start. Standing voltage 12.7, Charging Voltage 14.0
    Plates covered with electrolyte. Dealership states test equipment to check i-eloop Out Of Service. Also Understand that Mazda has discontinued after 2016.Need help

    Thank you
