BT168 Universal Battery Tester NJ4409

Product Details

• Universal Compatibility: Designed to test a wide variety of standard and rechargeable household batteries, including AA, AAA, C, D, 1N47, N, 9V (6F22), and various button cells.
• Clear Analog Display: Features an easy-to-read, color-coded meter scale that quickly identifies battery health status. The needle directly points to color zones—Green (Good), Yellow (Low power), and Red (Replace/Recharge)—eliminating any guesswork.
• Simple Mechanical Operation: Operates entirely via the tested battery's remaining electrical charge. An adjustable sliding arm accommodates different battery sizes securely to ensure proper contact during testing.
• Compact and Portable Design: Lightweight and pocket-sized construction makes it convenient for home organization, toolboxes, or travel use.
• No External Power Required: Built-in circuitry draws a minuscule load directly from the battery under test, meaning the device does not require internal batteries or a connection to a wall outlet to function.
