Mopar VU01207 Terminal-Battery Terminal

You can Select Your Vehicle to check if VU01207 fits your vehicle.

Always disconnect the negative cable first and hook it up last or the battery may be shorted by the tool being used to loosen the cable clamps. Disconnect both cables from the battery terminals. Remove the battery hold down clamp. Unscrew the nuts, remove the bolt, and lift off the locator bracket, then pull the hold down clamp off the battery. Lift out the battery. Be careful - it's heavy. While the battery is out, inspect the carrier (tray) for corrosion. If you are replacing the battery, make sure that you get one that's identical, with the same dimensions, amperage rating, cold cranking rating, etc. Installation is the reverse of removal.

Remove the spare tire access cover, disconnect the negative cable, remove the battery retention strap, disconnect the vent tube, remove the hold-down bolt and clamp, and lift out the battery. Install the new battery following the reverse of the removal steps.

Disconnect the negative battery cable and visually inspect the battery's state of charge using the indicator eye (if equipped). Charge the battery or add distilled water if needed. Use a hydrometer to check the specific gravity of the electrolyte in each cell. Perform an open circuit voltage test using a digital voltmeter, ensuring the battery voltage is above 12.5 volts. Use a battery load tester to evaluate the battery's ability to handle heavy amperage draw during startup and accessories operation. Cold temperatures may slightly affect the minimum voltage requirements. To test for battery drain, disconnect all accessories and check the current drain using a digital ammeter. Normal drain is around 100 milliamps or less, while excessive drain can cause battery discharge.

Look at the indicator eye on the top of the battery. A green eye indicates 75 to 100 percent charge, a black eye indicates 0 to 75 percent charge, and a clear eye indicates low electrolyte level.

Ensure that you purchase one that is identical in dimensions, amperage rating, and cold cranking rating.

Always disconnect the negative (-) battery cable first, followed by the positive (+) cable.

Measure the specific gravity with a hydrometer if the battery has removable cell caps. Some batteries have built-in hydrometers or can be checked with a digital voltmeter.

Transfer the thermal guard to the new battery.
