Following these steps will help your Cadillac's battery work well and last longer.Testing the New BatteryCheck if your new battery works well. First, use a multimeter to check the battery's voltage. A full car battery usually shows between 12.6 and 12.8 volts.Make sure the Cadillac's ignition and all electrical stuff are off before you test. Put the red probe of the multimeter on the positive terminal and the black probe on the negative terminal. If the reading is below 12.4 volts, the battery might need more charging.Next, do a load test to see if the battery can handle power when the car is running. Use a load tester to create a resistance equal to half of the battery's cold cranking amps (CCA) for 15 seconds.If the voltage stays above 9.6 volts during this test, the battery is doing fine.Battery Maintenance TipsTo keep your Cadillac's battery lasting longer and working well, you need to take care of it regularly. Check the battery terminals often for any white or greenish buildup. If you see any, clean it off with a mix of baking soda and water.
