In some cases, the problem may not be with your car battery charge at all but your battery terminals instead. Simply replace it and youвЂ™ll end up saving money in the end.Д¬hecking the terminals of your car battery using Ignoring it will only make it worse and a faulty alternator will slowly damage the battery. Anything below that will let you know that your alternator needs to be replaced. When the car is at idle, the voltage reading of the battery should range between 13v and 14.6v. A faulty alternator could prevent the battery from recharging correctly while you drive so that maybe your problem. You can also use that time to take a reading of the battery while itвЂ™s running, and see if your alternator is still doing his job. You could also just start the car and let it idle for about 10 minutes. If they arenвЂ™t, youвЂ™ll probably want to have your car battery replaced in the near future. Once itвЂ™s charged, perform the same test again and see if the readings are better. The voltage of a battery will gradually lower as time goes by so if the car hasnвЂ™t been started for a couple of days, itвЂ™s maybe totally normal. If you get a reading below 12.6v, the first thing youвЂ™ll want to do is to recharge your battery using a smart battery charger.

A fully charged battery could still die right away when the ignition key is turned as being full charge doesnвЂ™t been that it can still deliver enough power to make the starter turn in extreme cold weather conditions. ItвЂ™s worth mentioning here that your only measuring the voltage of the battery and not the cold-cranking amps. Lastly, if your battery is operating in critical condition and is at around 11.8 volts, this means that it is operating at around Вј or 25% of its full capacity.If the readings range between 12 and 12.3 volts, your battery is operating at Вѕ of its capacity and it should take you sometime before youвЂ™ll need to replace it.For readings that are over 12.5 volts, it means that your battery is fully charged and it is in good condition.Step 3: Provide a light load and check the readingsДЇirst, turn the ignition key to the ON position and turn the car headlights on for 30 seconds to eliminate any chance of parasitic charges that could give you false readings.ДЄ car batteryвЂ™s voltage is dependent on the outside temperature so assuming itвЂ™s 27 degrees Celsius, hereвЂ™s what you should make of the readings you see on the multimeter display:
