There are multiple different types of battery tester, each suited to varying battery types and sizes. Some of the most common types are detailed below.
Electronic Battery Tester
Electronic and digital battery testers are used to test the remaining capacity of a battery.
Most digital models feature an LCD display which presents the result of the battery test in a clear and easy to read format. Often displayed in the form of bars or a graph, depending on the particular model, this enables quick reading and analysis of the test results via a user-friendly interface.
Domestic Battery Tester
A domestic or household battery tester is normally used for rechargeable cylindrical batteries including AA batteries, AAA batteries, and 9V PP3 batteries.
Common battery chemistries include alkaline, NiCd, and Li-ion. These standard chemistry types cover the majority of everyday household batteries including those outlined above as well as additional battery types such as C batteries and D batteries. A typical domestic battery tester will be suitable for testing a combination of these battery types, if not all of them.
Universal Battery Tester
Universal battery testers are suitable for use with batteries in a range of different sizes. Similarly to domestic battery testers, they are primarily used for cylindrical batteries.
However, some voltage meters can test a large variety of different-sized batteries, ranging from smaller button cell batteries through to larger industrial and automotive batteries.
Car Battery Tester
Car battery testers are intended for use with lead-acid batteries. These testers connect to vehicle batteries to provide a clear indication of the battery’s health, condition, and voltage output.
Battery testers for automotive applications are important. It is crucial to determine the condition of car batteries as high currents are drawn during start-up. You must ensure that your tester is compatible with lead-acid batteries before use, in order to ensure safe testing conditions.
