Diagnostic Aids
- For 2019 and Newer North American Vehicle only we have am OEM (as built with) reference table available in SI under General Information > General Information > 12 V Battery Usage.
- For accurate test results the battery must be disconnected from the vehicle and the equipment connected directly to the battery posts.
- Failure to obtain the correct connections during the test may result in a failed test on a good battery.
- For Dual Batteries both of the batteries must be disconnected with test equipment connected directly to the posts. Each battery needs to be tested separately.
- For battery replacement warranty claims, the complete 15-character (17 with hyphens) test code from the EL-50313 Midtronics GR8 Battery Tester/Charger or 20-character (no hyphens) test code from the EL-52800 E-XTEQ Diagnostic Charge Battery Station (DCBS) must be included in the Labor Code Dependency field in GWM,
NOTE:
For Warranty Repairs - You must use the regionally required battery test equipment refer to Special Tools (Removal and Installation) .
- Setup:
- When using the GR8, Select "Charging," "Diagnostic" when setting up the test. and then select the correct battery type (Flooded, AGM, or Stop/Start AGM) and rated CCA (both from the battery label) must be entered. Use the Out of Vehicle test (battery disconnected with test equipment connected directly to the posts) for each battery when testing a vehicle with dual batteries.
- When using the DCBS, Select "Diagnostic" and "Trolley", then scan the VIN and verify the battery selection is correct, or manually select the correct battery type (Flooded or AGM) and rated CCA (both from the battery label).
Cold Battery Testing - Battery Temperature Less Than 0° C (32° F)
- Cold batteries are resistant to charging even when in use on the vehicle. They will not recover quickly in subfreezing temperatures. Releasing a new vehicle with a battery in a low state of charge puts the customer at risk to a no crank event.
- If you suspect that a battery may be frozen, inspect the case for cracks prior to charging. Do not charge a frozen battery.
- When an automotive 12 Volt battery is cold (below freezing), its capacity starts to reduce. This can be observed in the voltage level of the battery, as well as measured cold cranking amps. A cold battery is also resistant to charging. The colder the battery, the more these characteristics are affected.
- Depending how cold a battery is, it can fail testing using any type of battery test equipment.
