DLYPOW Universal Battery Tester LCD Battery Checker for AA, AAA, 9V and More

Meet the DLYPOW Universal Battery Tester, a compact tool designed to simplify household battery management. It helps you identify which batteries still hold a useful charge and which should be recycled or replaced, all without guesswork. The ergonomics feel natural in your hand, and the LCD readout offers a clear snapshot of each battery's current voltage.

Designed for versatility, this tester works with a broad spectrum of chemistries and sizes. Whether you’re checking everyday AA and AAA cells, larger C and D cells, rechargeable Ni-MH, alkaline, Li-ion, or nine-volt blocks, the device covers most household needs without swapping gadgets.

What it tests and how it works

• Compatibility with 1.2V Ni-MH, 1.5V Alkaline, 3.0V Lithium, 3.7V Li-ion, and 9V batteries.
• Supports common sizes including AA, AAA, C, D, 18650, CR123A, LR44, CR2032 and other button cells.
• Three-step testing: select voltage range, insert the battery with correct polarity, and read the result on the LCD.

Smart health feedback without pressure

• Color-coded status indicates Good, Weak, or Replace in a friendly, intuitive way.
• Open-circuit testing draws no power from the tested battery, so your sample remains untouched.

Compact, rechargeable, and ready to use

• Magnetic buckle helps keep batteries secure for steady readings during testing.
• USB-C charging supports long standby—roughly 2–3 months per full charge—reducing frequent swaps.
• Ultra-lightweight design makes it simple to store in a drawer or bag for on-the-go checks.

What’s included and guaranteed

Each package includes the DLYPOW-DB1 Tester, a USB-C charging cable, a quick-start guide, a 12-month warranty, and friendly customer support.
