Today's automobiles are sophisticated machines with Gps navigation, Lcd screens, Dvd players and iPods. However, all of these 21st century technological wonders are still at the mercy of the car battery and the automobiles electrical system. Car batteries have improved over the years but the technology is basically the same. Most of us do not even think of our car battery until our reliable car refuses to start and we are stranded in a parking lot. A modern car battery tester can rate trouble with your automotive battery and conclude the definite procedure of activity a technician needs to take.
Car battery testers use the BCI adjustable load test as a measurement to conclude if your car's battery is usable or needs to be replaced. The car battery tester measures the voltage drop when an applied load that is ½ the car battery's Cca rating is used. The load is applied for at least 15 seconds and the voltage drop is measured. The voltage should not drop below 9.6 volts for the battery to be carefully good. (Also the ambient climatic characteristic should be colse to 70° F) For example, you have a battery with Cold Cranking Amp rating of 600 Cca. You would apply a load of 300 amps for 15 seconds. If the measured voltage does go below 9.6 volts, the battery is still good. It is potential to use a car battery tester in differing climatic characteristic conditions, but you must compensate for the divergence in your calculations.
CAR Jump Battery
If the car battery has been thoroughly discharged, you will have to recharge it using a convenient car battery charger. Do not endeavor to use a quick charger type battery charger if yours is in this condition. These types of automotive battery chargers use a high current to get you fast results. This high current can damage the sensitive plates in your battery when it is in a fully discharged state. an additional one method to avoid is just to get a pair of jumper cables and jump start the dead car and then let the alternator recharge it. Your car's alternator is not a car battery charger and it cannot recharge a totally discharged battery without getting damaged.Be sure to let the battery cool down to room temperature. Habitancy often forget how hot it gets inside of an engine compartment, especially in the summer months. That goes for cold weather as well. You may have to let the battery warm up to room temperature. Batteries achieve differently at climatic characteristic extremes and that's why its prominent to use room climatic characteristic as the acceptable to accurately quantum them.
