Questions about this product
- Will this tester work with my specific household and button cell batteries?
- Yes, it's highly versatile. It tests standard AA, AAA, C, D, and 9V batteries, along with small N cells and button cells. You can even use it to check power banks.
- What is the voltage range of this tester, and can it measure 12V car batteries?
- This device measures direct current voltages from 1.2V up to 9V. Because of this limit, you can't use it for 12V car batteries. It delivers accurate readings within plus or minus one percent.
- How do I use this tester to check if my smoke detector battery is still good?
- Just press the battery against the spring-loaded contacts. The clear LCD screen instantly displays the exact voltage reading. This helps you quickly decide if your 9V safety batteries need a replacement.
