XTAR L4 Pro 4 Channel AA/AAA lithium & NiMh Smart Charger

Key Features

• Universal AA/AAA Smart Charging: One charger for all of your AA and AAA rechargeables — auto-detects 1.5V li-ion and 1.2V NiMH cells across four independent slots and applies the right charging method to each one automatically.
• HD LCD Display: A proper HD LCD screen shows battery level bars and real-time charge status for all four slots at once — no guessing, no waiting to find out if a charge actually completed.
• Multi-Stage NiMH Refresh Mode: Quick Refresh and Smart Deep Refresh modes work to eliminate memory effect and restore real usable capacity to aging NiMH cells — not just fill them to whatever capacity they have left.
• Micro-Current Activation for Over-Discharged Batteries: The L4 Pro uses 200mA micro-current activation to bring back deeply over-discharged batteries at higher recovery rates — cells that most chargers would simply refuse to charge.
• Seven Built-In Safety Protections: Auto-stop, reverse polarity, over-current, over-voltage, over-charge, short-circuit protection, and over-discharged battery activation — all built in so you can charge with confidence and walk away.

Overview

The XTAR L4 Pro is where the standard L4 leaves off. It keeps the same four-slot USB-C convenience and wide 1.5V li-ion and 1.2V NiMH compatibility, then adds the features that actually matter when you are serious about your rechargeable batteries. The HD LCD display shows you exactly what is happening in each slot in real time. The multi-stage NiMH refresh system — Quick Refresh for everyday restoration and Smart Deep Refresh for more deeply degraded cells — eliminates memory effect and gets your NiMH batteries working like new again rather than just cycling through whatever capacity remains. The 200mA micro-current activation revives over-discharged cells that a standard charger would skip entirely. CVSA technology and four full-charge detection methods ensure precise, complete charging with lower heat across every session. Built with fireproof ABS+PC/V0 housing and weighing just 87g, it is compact enough to keep anywhere. Compatible with a wide range of 1.5V li-ion and 1.2V NiMH brands including XTAR, Eneloop, Energizer, EBL, and Duracell.
