Best Car Battery Tester Reviews in 2021

A battery tester is an electronic device intended for testing the state of an electric battery, going from a simple device (such as Launch BST360, XTUNER PT101, OTOFIX BT1 Lite) for testing the charge actually present in the cells and/or its voltage output, to a more comprehensive testing of the battery’s condition (such as OTOFIX BT1, Foxwell BT-715) , namely its capacity for accumulating charge and any possible flaws affecting the battery’s performance and security.

Why and when should you test your battery? Since you may need to use the electrical systems in your car constantly, it is crucial that you check the condition of your car battery from time to time to prevent your car from being stranded in the parking lot when you need it. There are some obvious symptoms for a failing battery. Whenever you notice the starter motor cranking the engine unusually slow, maybe that’s a sign to check the condition of your car batteries before it’s too late. Sometimes you can tell by the illuminated battery/charging warning lamp on the dashboard. Dimmed headlights is another indicator of battery problems.

To avoid being stranded due to a battery problem, it’s recommended to have the battery inspected frequently and make sure the cables are clean and tight. If you’ve already used a battery for around three years, you may need to test it annually. The test will help identify if the battery has reached a point where a replacement is needed to prevent an unwanted failure.
