What It Is / How It Works

The ANENG 168Max is a digital battery tester for household cells. It reads the charge level of AA, AAA, C, D, 9V, and 3.7V lithium batteries, along with button cells like CR2032 and LR44. A digital display shows the result, so you can sort batteries into keep and recycle piles instead of guessing which ones still have power.

Who It's For / Use Cases

Battery testers suit homeowners who want to check cells before throwing them away, DIY enthusiasts and hobbyists who work with several battery types, and anyone using rechargeable lithium cells such as 18650 or 14500 who wants to monitor charge status. They also help households with many battery-powered devices keep their batteries sorted.

How to Use / Care

1. Place the battery between the two contact points.
2. Read the charge level on the digital display.
3. Check button cells such as CR2032 and LR44 the same way.
4. Use it to monitor the charge status of rechargeable lithium cells like 18650 or 14500.

How to Choose

Start with the battery sizes you actually use. A tester that covers AA, AAA, C, D, 9V, and 3.7V lithium cells handles most household devices, while button cell support matters if you replace watch or calculator batteries. Check the voltage range against the cells you plan to test, and consider a compact body if the tester will live in a drawer or tool bag.
