• Broad Compatibility, Polarity-Free: Supports any brand of AA and AAA Ni-MH batteries, plus our Ecolast 1.5V AA rechargeable Li-ion batteries. Drop cells in any direction—no (+)/(-) alignment needed.
• Auto-Detect, Charge & Sort: Leading-edge per-cell management system checks each battery before charging. Only healthy batteries charge, while incompatible or unhealthy cells are automatically removed. Saves time and prevents mix-ups.
