Vehicle battery maintenance is important for reliable starts. Also, you must shut off the engine and disconnect the negative cable before working on the battery. Inspect the battery for damage and weak connections. Reattach the battery, secure the nuts to the proper torque, and inspect the battery tray as well as the clamp bolts.

Disconnect the negative battery cable, then the positive cable from the battery. If the radio in your vehicle is equipped with an anti-theft system, make sure you have the correct activation code before disconnecting the battery. Check the battery state of charge. Visually inspect the indicator eye on the top of the battery; if the indicator eye is black in color charge the battery. Next perform an open voltage circuit test using a digital voltmeter. The battery's surface charge must be removed before accurate voltage measurements can be made. Turn On the high beams for ten seconds, then turn them off, let the vehicle stand for two minutes. Perform a battery load test. An accurate check of the battery condition can only be performed with a load tester. This test evaluates the ability of the battery to operate the starter and other accessories during periods of heavy amperage draw. Install a special battery load testing tool onto the terminals. Load test the battery according to the manufacturer's instructions for the particular tool. Disconnect the negative battery cable, then the positive cable from the battery. 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. Remove the battery hold-down clamp. Lift out the battery. Be careful - it's heavy. While the battery is out, inspect the battery tray for corrosion. If corrosion exists on the battery tray, detach the bolts and remove the tray from the engine compartment. Clean the deposits from the metal to prevent the battery tray from further corrosion. If you are replacing the battery, make sure you get one that's identical, with the same dimensions, amperage rating, cold cranking rating, etc. Installation is the reverse of removal.

First of all, turn off the engine and disconnect the negative cable before servicing the battery. Inspect the battery for damage or corrosion. If present, clean the battery with a baking soda solution. Inspect and clean the battery carrier and brackets. Reinstall the battery, add felt washers around the terminals, and coat them with petroleum jelly to prevent corrosion. Tighten all clamps and check the battery tray. For charging, use a slow-rate charger. Avoid chargers rated more than 1/10th the battery's amp/hour rating.

You need a face shield/safety goggles, rubber gloves, battery post/cable cleaner, treated felt washers, baking soda, and petroleum jelly.

Battery electrolyte contains poisonous and corrosive sulfuric acid, so you should avoid contact with eyes, skin, or clothes, and never ingest it. Protective safety glasses should be worn, and children should be kept away from the battery.

The battery produces flammable and explosive hydrogen gas.

Remove the battery hold-down clamp.

You should remove the key from the ignition when disconnecting the battery to prevent accidental locking of the power door locks when reconnecting the battery.

Memory-savers are used to maintain power to certain circuits while disconnecting the battery.

Visually inspect the indicator eye on the top of the battery. If the indicator eye is black in color, charge the battery.

Cold temperatures will cause the minimum voltage requirements to drop slightly. Follow the chart given in the manufacturer's instructions to compensate for cold climates. The minimum load voltage for freezing temperatures (32 degrees F) should be approximately 9.1 volts.

Simply reverse the removal process, making sure to connect the positive cable first and the negative cable last.

Inspect the battery tray for corrosion. If corrosion exists, detach the bolts and remove the tray from the engine compartment to clean it.

Inspect the battery tray for corrosion.

Routine preventive maintenance for your vehicle's battery is crucial for ensuring quick and reliable starts.

Memory savers can be used to deliver sufficient current to maintain security alarm codes and PCM memory while isolating the car battery.

The heat shield from the old battery should be removed and installed on the new battery.

Ensure the battery tray is in good condition, and the hold-down clamp bolts are tight. Any metal parts damaged by corrosion should be covered with a zinc-based primer and painted.
