*by J***S on May 1, 2026*

### ⭐⭐⭐⭐⭐ Great Tester
*by M***. on May 14, 2026*

This is a great tester. This is my second unit. I bought one for my home. I just bought this one for my business. Any battery tester will tell you the voltage, but this one also analyzes the percentage of remaining power.

### ⭐⭐⭐⭐ seems to work well
*by A***Y on March 29, 2026*

This seems to work, and is probably more accurate than less expensive voltage testers. Only downside is that it is a bit awkward to use; the positive terminal is on the device, and the battery must be held in a slightly awkward position for a few seconds to test. This is a minor issue most of the time.
