Overview

Stop throwing away dead batteries! This isnt just a chargerits 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 arent 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.
