Attention: Only measurement function (i.e. the remaining battery capacity) is available, rather than directly
detecting the battery capacity. Please do not misunderstand. This product can only measure 1.5V and 9V batteries. Measuring batteries with other voltages may burn out the instrument This product does not require a built-in battery for measurement and displays the battery level relying on the tested battery What is the displayed voltage of the battery measured by this product. The voltage of the battery is directly proportional to its charge, and the higher the voltage, the more sufficient the battery charge is This product mainly measures whether the battery is charged or not. Please do not purchase non professional voltage measuring instruments that require it!

🔹 Why Choose This Module?

• Tests under load — reveals actual usable remaining capacity
• Covers AA, AAA, C, D, and 9 V — all common battery types
• Good/Weak/Replace indication — instant clear result
• No batteries required — powers from the tested battery
• Compact size — keeps in every toolbox

🔹 Technical Specifications

• Battery Types: AA, AAA, C, D, 9 V
• Test Method: Under-load voltage measurement
• Indication: Good / Weak / Replace
• Power: Self-powered from tested battery

🔹 What's Included

1 × AA-9V Multi-Type Battery Tester

🔹 Pro Tip

💡 Always test batteries under load — a 9 V battery showing 8.5 V open-circuit may drop to 5 V under load and be functionally dead. Replace batteries showing 'Weak' in high-drain devices (cameras, remotes) even if they work fine in low-drain devices (clocks).

⚠️ Note: Always ensure proper heat dissipation and correct voltage configuration before powering connected devices.
