Buying Guide

If you are having a hard time choosing a battery tester for both household and commercial purposes, below are some buying advice that we would like to recommend for you.

Compatibility:

the wider compatibility the battery tester has, the better it is. This is because it can work with a variety of items that are based on different types of batteries, such as AA, AAA, 1.5v, 9v, 2CR5, and many other common types of battery.

Easy to read:

it should come with an LCD screen to display the battery status in an easy to read way. No matter what kind of lighting conditions you have, you should be able to read clearly.

Indicator light:

the machine should provide a clear indicator light as well. In case of a good battery condition, it should display the color in green. However, when the battery power is low, the color turns yellow, and later on, it will turn green when the battery runs out of power and becomes in need of recharging or replacement.

Portable size:

the smaller the battery tester is, the more convenient for users to work with. Nowadays, the tester gets smaller and smaller to let users work with it for both indoors and outdoors.
