Review: This Battery Tester works very well. Accurate and Informative. - I read about this device in an on-line article since I was in the market for a battery tester. I can't count the number of battery powered devices in my house and when one of them stops working the first thing I need to check is the batteries. I have a battery tester that is part of a battery storage tray but it's very rudimentary and permanently attached to the tray. I needed one that I can take to the malfunctioning device. The article I read pointed to a device that meets this criteria. I ordered this one based on the recommendation in the article. When it came in I was ready to try it with a number of batteries I had put aside for the purpose of checking out this tester. I used it to check various battery types (AA-Alkaline, AAA-Alkaline, Ni-CAD, L-ion). The results confirmed that the batteries were generally in the condition I suspected they were in. The readings displayed showed the terminal voltage and the percent of charge remaining. I worked as an electronics engineer designing test equipment so I'm always looking for inadequacies in stuff like this. I can say I have 100% confidence in the tester. If you have a lot of battery powered devices, get one. I'm glad I did.
Review: Very good battery tester - It is an excellent item at a great price, well packed, and delivered promptly with no issues. The seller is an A+++ on desertcart!

### ⭐⭐⭐⭐ Working ok, instruction booklet could be more helpful.
*by M***N on January 27, 2025*

Seems to be working ok. The instruction booklet could be more helpful. I was confused at first because the display does not show anything, there is no on/off switch. There is 1 button I had thought would serve that purpose but it does not, it turns on the display very briefly and then shuts down. Ignore the button and just put the battery positive on charger and use the tester stick on the negative, then the display will show.
