(See GR8-1291 INSTANT TRAINING MODULE (VIDEO).)
WARNING:
Keep all flames away from the battery, otherwise evaporated gas from the battery fluid may catch fire and cause serious injury.
1. Remove the battery filler caps and check the water level. If necessary, add water to the appropriate level. Reinstall the caps.
2. Attach the large red clamp to the positive battery terminal and the large black clamp to the negative terminal.
3. Select the diagnostic icon in the Main Menu, then press the NEXT key.
4. Follow the on-screen instructions to input the appropriate information. Refer to the Mazda GR8-1291 Instruction Manual for more information.
5. The GR8-1291 will test and charge the battery. Before the diagnostic charging results are displayed, use the keypad on the Control Module to input the last 5 digits of the vehicle's VIN and press NEXT to continue.
6. After the charging is completed, the Mazda GR8-1291 will print out the diagnostic charging results and display one of the following results listed below. Review the results and follow the action step for the displayed result.
| Battery Tester Display | Action Step |
| GOOD BATTERY | Return the battery to service. |
| REPLACE BATTERY | Replace the battery. |
| BAD CELL - REPLACE | Replace the battery. WARNING:
|
| SIDE POST TEST | Test data was inconclusive using the side post. Retest using side post adapters. |
| JUMP START POST | Data was inconclusive using the jump start post. Retest at the battery terminals. |
WARNING:
Keep all flames away from the battery, otherwise evaporated gas from the battery fluid may catch fire and cause serious injury.
Remove the battery filler caps when recharging to prevent battery deformation or damage.
CAUTION:
Do not quick charge for more than 30 min. Otherwise, it will damage the battery.
1. Remove the battery. (See BATTERY REMOVAL/INSTALLATION [SKYACTIV-G 2.5].)
2. Remove the battery filler caps.
3. Connect a battery charger to the battery and adjust the charging current as follows.Battery slow charge current (without i-ELOOP)
55D23L (60 A·h/20HR): 4.5—5.5 A
75D23L (65 A·h/20HR): 5.0—6.0 A
Battery quick charge current [30 min] (without i-ELOOP)
55D23L (60 A·h/20HR): 30 A
75D23L (65 A·h/20HR): 35 A
4. After the battery is recharged, verify that the voltage is within the specification and remains at the same value for 1 h or more after the recharging has been completed.
If not within specification, replace the battery.
Standard voltage
12.4 V or more
WARNING:
Keep all flames away from the battery and perform the servicing in a well-ventilated area. Otherwise, evaporated gas from the battery could ignite.
Remove the battery filler caps when recharging to prevent battery deformation or damage.
Do not perform battery recharging with the battery in the vehicle as it is dangerous.
When connecting to the battery recharger, make sure the battery cables are connected correctly.
CAUTION:
After recharging, leave the battery as it is for as long as possible (6 hours or longer recommended) to dissipate the polarization in the battery.
1. Remove the battery. (See BATTERY REMOVAL/INSTALLATION [SKYACTIV-G 2.5].)
2. Remove the battery filler caps.
3. To prevent loss of battery fluid during recharging, verify the battery fluid level.Battery fluid level is between upper and lower or less
Add distilled water to the upper level.
Battery fluid level is between upper and lower or more
Go to the next step.
4. Connect a battery recharger to the battery and adjust the charging current as follows.Battery recharge time (Table 1)Constant current recharger device available
Apply a constant current charge so that the recharge current is 10 to 15 A. Perform the battery charge time referring to table (1).
Cell with lowest electrolyte gravity
1.24 or more
1.23

No constant current recharger device available
Adjust the voltage so that the recharge current is 10 to 15 A.
Verify the current after 30 s have elapsed since the measurement was started because the current is not stabilized after the voltage adjustment.
Charge the battery for 60 min using current in Step (1).
Readjust the battery recharger so that the recharge current is 10 to 15 A.
Charge the battery so that the total time for Step (2) is the time in table (1).
5. Measure electrolyte gravity of all cells.Cell with lowest electrolyte gravity is less than 1.25
Replace the battery as battery charge could not be restored. (See BATTERY REMOVAL/INSTALLATION [SKYACTIV-G 2.5].)
Cell with lowest electrolyte gravity is 1.25 or more
Battery charge was restored, therefore install the recharged battery into the vehicle. (See BATTERY REMOVAL/INSTALLATION [SKYACTIV-G 2.5].)
