  Q: How to Check and Replace a Battery in a Chrysler 300?

  A: Always disconnect the negative cable first and hook it up last to avoid accidentally shorting the battery. To check the battery state of charge, look at the indicator eye on 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. If the battery is maintenance-free and the eye is clear, replace the battery. If it has removable cell caps, add enough water to bring it to the correct level. Perform an open-voltage circuit test using a voltmeter to check the battery's voltage, which should be at least 12.4 volts. Charge the battery if necessary. Perform a battery load test using a battery load tester to evaluate its ability to operate the starter and accessories under heavy load. Connect the tester and apply a load of 50 percent of the cold cranking amperage rating for a maximum of 15 seconds. The battery voltage should not drop below 9.6 volts. If the battery is weak or defective, the tester will indicate this. To replace the battery, 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. Inspect and clean the tray and surrounding metal if necessary. Install the new battery following the reverse of the removal steps. To replace the battery tray, remove the battery, detach the Power Distribution Center, remove the mounting bolts, and remove the tray. Install the new tray following the reverse of the removal steps.
