89 volts = 0% charged<\/li>\n<\/ul>\na battery at 27\u00b0c or 80\u00b0c will show the above values. for every 10 degrees change in the temperature, the voltage on the car battery will change by .01 volts.<\/p>\n
step 4: understand the readings<\/h3>\n
<\/p>\n
does the car battery read more than 12.45 volts? if it does, then it has a proper charge. but if you record lesser values, recharge the cell and take to an auto shop for testing.<\/p>\n
the results of a charge test do not show if you have a bad or good battery. instead, it signifies the present condition of the charge. so if the cell has low power, a quick top-up can make it work. overall, good batteries store energy better than weak ones.<\/p>\n
step 5: recharge your car battery<\/h3>\n
<\/p>\n
when you have a battery with a low charge, recharge it, and repeat the test. to restore the cell to its full strength, use an alternator or portable charger.<\/p>\n
if you prefer using the alternator, start by charging the engine with a pair of jumper cables. next, drive the vehicle for less than 30 minutes. you can even charge the battery by removing it from the vehicle, and taking it to an auto parts store.<\/p>\n
step 6: test the car battery<\/h3>\n
<\/p>\n
after charging the item, you should know how to test 2022卡塔尔世界杯预选赛时间 battery for dead cell or good working one<\/strong>. you can use any of the methods to check the charge on the cell.<\/p>\n\n- load tester: the test involves applying a load to the cell while the checker checks the voltage on it. if you have a reading of 9.6 volts, consider replacing the battery.<\/li>\n
- via an electronic tester: here, you can detect the status of the battery cells with the use of frequency waves.<\/li>\n<\/ul>\n
if you don\u2019t know how to check 2022卡塔尔世界杯预选赛时间 battery at home with the above-mentioned method, <\/strong>take it to a local auto parts store.<\/p>\nusing the alternator<\/h2>\n
<\/p>\n
this component is a vital component of a vehicle. the alternator charges up the batteries, when the engine is functioning. it even creates electrical energy that it uses to power devices in the vehicle.<\/p>\n
to test the car battery with this method, you will need a multimeter handy. use the device to confirm the condition of the vehicle’s alternator.<\/p>\n
if you don’t know how to use it, look up the steps in the how-to test 2022卡塔尔世界杯预选赛时间 battery with a digital multimeter <\/strong>above. <\/strong>during the test, leave the engine at idle speed <\/strong>and look for a 13.8v – 14.4v reading on the instrument.<\/strong><\/p>\nif you have a reading of fewer than 13.8 volts, this means that the vehicle has an undercharged battery. but if it exceeds 14.4 volts, the battery is overcharged. since both readings discovered can damage the battery, you will need to call a professional to have a look at the alternator.<\/p>\n
learning how to test 2022卡塔尔世界杯预选赛时间 battery comes as an essential skill for any driver. but if you don’t have the latest battery, you should learn how to how to test 2022卡塔尔世界杯预选赛时间 battery without a multimeter<\/strong>.<\/p>\nhow to test 2022卡塔尔世界杯预选赛时间 battery with a hydrometer<\/h2>\n
