Universal Battery Charger & Analyzer – AA, AAA, 9V with Refresh & Discharge Function

Overview

Stop throwing away “dead” batteries! This isn’t just a charger—it’s a diagnostic tool. The built-in Discharge & Refresh function allows you to completely drain a battery and then recharge it. This process breaks down crystalline buildup in Ni-MH cells, effectively “exercising” them and restoring them to near-original capacity. It is the perfect choice for photographers, technicians, and hobbyists who need reliable power.

Key Features

• Advanced Discharge/Refresh: Cycle your batteries to maintain optimal health and measure their true remaining capacity.

• Universal Compatibility: Handles the most common sizes: AA, AAA, and 9V.

• Intelligent Auto-Cutoff: Prevents over-charging with precise voltage sensing ($-\Delta V$ technology), ensuring your batteries aren’t stressed.

• Low Current Mode (20mA): Perfect for “trickle charging” or safely charging very low-capacity/old batteries without overheating them.

• Status Display: Individual indicators for each channel so you know exactly which battery is charging, discharging, or ready.
