From the shop's description

Universal Battery Tester (C/AA/AAA/D/N/9V/6F2/1.55V) Universal Battery Tester is a Multi-Cell Digital Battery Analyzer (C/AA/AAA/D/N/9V/Button Cells) is a handheld instrument that quickly gauges the remaining charge in common batteries. It supports standard 1.5V cells (sizes C, AA, AAA, D, N) and 9V (6F22) blocks, as well as 1.55V button cells​. The tester features a digital LCD with a color-coded bar-graph readout to display each battery’s voltage and condition (Good/Weak/Replace). Unlike a simple voltmeter, it applies a small internal load so the reading reflects real-world battery performance. The device draws only minimal power and is powered by the battery under test (no internal battery required), keeping testing quick and avoiding additional discharge. Features: Ease of Use and Portability Its small size and intuitive design make it ideal for use in various settings, from home utility drawers to travel toolkits. High-Quality Performance Delivers consistent and trouble-free operation, ensuring reliable results with every test. Tri-Color Meter Provides a clear visual indication of battery strength with three color-coded zones (good, weak, poor), simplifying the assessment process. Accurate Power Assessment Precisely measures the remaining power capacity of batteries, helping users avoid device failures due to weak batteries. Instant Readouts Offers practical and immediate results, allowing for quick decision-making. Durable Construction Made with durable plastic and stainless steel, ensuring the device withstands regular use. No External Power Required Operates using the power of the battery being tested, eliminating the need for additional batteries or power sources.
