Battery testers are commonly used in garages and by people who use batteries a lot more frequently. These battery testers are compact, light in weight and tell the status of batteries by drawing heavy current from the battery while measuring its voltage level. The voltage level of a good battery remains relatively steady under load, but a defective battery will show a rapid loss in voltage. Battery size (CCA rating) and temperature also affect the test results.
There is no shortage of battery testers but what the people need are accurate ones. The following article lists the best and the most reliable battery testers. Have a look and let us know which battery tester do you use.
