A strong battery holder or contact arm is also important to me because it helps the tester work more consistently over time.
Display and Readability

The BT-168 usually uses a simple analog needle display, and I find that helpful because I can quickly see whether a battery is low, weak, or good. For me, clear labels on the dial matter just as much as the needle movement.
Compatibility with Battery Types
I make sure the tester supports the battery types I use most often. In my home, that usually means AA and AAA batteries, but I also like having the option to test 9V and button batteries. A good BT-168 should cover these common sizes so I do not need multiple tools for different batteries.

Accuracy and Reliability
I do not expect a battery tester like this to give laboratory-level precision, but I do want it to be reliable. I look for consistent readings when I test the same battery more than once. If the tester gives stable and repeatable results, I trust it more.
Price and Value
For me, the BT-168 is attractive because it is usually affordable. I look at the price alongside the features and build quality. If it is inexpensive but still gives dependable results, I see it as a good value. I prefer to spend a little more only if the materials and performance feel noticeably better.
