5 an hour before a test and preferably an hour. This also means the battery should be on a charger for at least. After 15 seconds it should be a minimum of 10.2 volts. The only way to determine this is by load testing the battery and applying a load equal to 3 X the starter current draw. That does not tell you what the voltage is when a heavy load is applied such as a starter motor. There’s nothing wrong with the 12.79 volts except for one thing. Keeping battery booster cables handy all the time just makes good sense, but in reality, proper preventive maintenance is what keeps you off the shoulder of the road. It doesn’t hurt to have an in-vehicle load test done at least once every 2 to 3 years to ensure the charging system works properly. Some less than others.Īlways buy the highest CCA battery and keep BOTH ends of the battery cables/ connectors clean and on wrench tight. Batteries are usually good for 5 years on average. This is why I asked how old the battery is. So, during warm weather you should be ok, but come winter (depending on your location) you might want to replace the battery. The CCA (cold Cranking Amps) is somewhat low and during a cold temp period it may not be strong enough to turn the engine over. When cranking the starter it will likely (temporarily) fall to about 8.5V to 9.5V. If the charging system is working right, it will likely read around 13-14V when running.
IF they measured properly, the battery shows it is/was fully charged. Vehicle mileage and year? 3.8L V6 engine? Putting walmart aside for now, tell us how old the battery is.
