Car Battery Testers Buying Guide
Go to top
Battery Compatibility: Obviously, there are several battery types, and not every tester works with all of them. However, some testers work with most types of batteries, which range from the AGM and gel cell types to conventional batteries and other types. The most important thing is to find a tester that’s compatible with your car battery. Otherwise, those who use the testers for commercial purposes should find a broad-spectrum type that works with almost all battery types.
Functionality: The basic functionality of testers is checking the power level of batteries. However, modern types have additional functionalities that are also necessary for the car owner. Features like checking the alternator functionality, as well as giving you information about the battery’s charging system, and other stuff, are quite useful. However, it’s important to understand that additional functionality comes at a greater price. So choose what you need and get ready to pay an extra dime for it.
Cable Length: A few testers feature shorter cables that require you to stay close to the battery if you want to test it. Others will let you enjoy the read as far as inside your car. Commercial testers’ cables don’t have to be long, unlike individual models that will feel comfortable when long. Please check to verify that the cables are in the right condition before use.
Ease Of Use: No tester should be difficult to use. They often need a simple plug-in, reading, and understanding. And, most of them will not need assembling, except for a few that need a bit of some straightforward DIY setup. The best testers should also have a convenient display platform that’s easy to read. Let’s talk about the display below.
The Display: You get to see all the results of the parameters measured by your tester on its display screen. Choose a tester with a clear display which you don’t have to look at again for the right reading. The display should be large and clear. Likewise, choose a backlit display system that enables you to take readings even in the dark.
