Jeep BB94R750AA Battery-Storage

You can Select Your Vehicle to check if BB94R750AA fits your vehicle.

To check the battery state of charge, inspect the indicator eye on the top of the battery, where a green color indicates 75 to 100 percent charge, black signifies 0 to 75 percent charge, and a clear or bright appearance indicates low electrolyte level. Maintenance-free factory-installed batteries cannot have water added, but if a low-maintenance battery with removable cell caps is used, add water to the correct level. Overcharging may cause low-electrolyte conditions, so after recharging, check the alternator charging voltage and replace it if necessary. Perform an open-voltage circuit test using a voltmeter to ensure the battery charge is correct. For a battery load test, use a battery load tester to evaluate its ability to handle heavy amperage draw. Disconnect the battery cables starting with the negative terminal, remove the battery hold-down bolt and clamp, then lift out the battery for replacement. Inspect the battery tray for corrosion and clean it as needed. For battery tray removal, disconnect wiring harness clips, remove the fuse and relay box, ABS controller, left front wheel, and wheelhouse splash shield if necessary, and then unbolt and remove the battery tray. The right-side battery tray removal process is similar, with additional steps for air filter housing and relay bracket removal.

Disconnect the negative cable first and hook it up last to avoid accidentally shorting the battery.

Proper battery maintenance is crucial to ensure reliable starts in your vehicle.

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

Disconnect the battery cables starting with the negative terminal, remove the battery hold-down bolt and clamp, then lift out the battery for replacement.

If corrosion is evident, the battery should be removed for cleaning by loosening the cable clamp bolts and disconnecting the hold-down clamp bolt and nut. The cable clamps should be thoroughly cleaned with a battery brush or terminal cleaner and a solution of warm water and baking soda. The terminals and top of the battery case should be washed with the same solution, being careful not to let it get into the battery. The battery posts should be cleaned with a terminal cleaner if extensively corroded. All cleaned areas should be thoroughly washed with plain water.

Gain access to the battery, unplug the electrical connector from the Intelligent Battery Sensor (IBS) if equipped, and disconnect the cable from the negative terminal of the main battery and the auxiliary battery. Disconnect the cable from the positive terminal of the auxiliary battery and the vent hose from both batteries. Remove the nut from the auxiliary battery hold-down strap and lift the battery from the tray. Installation is the reverse of removal.
