Check Household Battery Voltage

Includes one black BT189 battery tester. Batteries shown in the photos are not included.
Product Details
- Digital LCD voltage display.

- A dedicated button-cell contact area, with a supplier-listed 1.2–4.8V marking.
- Compact handheld design for household use.
Before Testing
Confirm that your battery's size, chemistry, and voltage are supported by the manufacturer's instructions. Match the positive and negative terminals to the tester markings and test one battery at a time.
A voltage reading alone does not establish remaining capacity or expected runtime. This tester does not charge batteries and is not a full battery-health analyzer.
Do not test leaking, swollen, damaged, or hot batteries. Keep batteries, especially button cells, out of children's reach and follow the battery manufacturer's handling guidance.

Excellent quality and works very well and is useful, although some batteries don't show any markings; I imagine they have no charge at all, but it's still highly recommended and the delivery was excellent.
I had a lot of leftover batteries at home, and when I checked with this product, I found that there were also new batteries mixed in. I recommend it.
Received it, the packaging was slightly dented, but the tester is intact and in working condition. Overall, I'm satisfied - it's lightweight, "compact", detects voltage and charge without any unnecessary features, easy to understand - what more could you want? You take it and use it, it breaks down - you buy a new one, the price is reasonable. I recommend both the seller and the tester.
