XTAR L4 4 Channel AA/AAA lithium & NiMh Battery Charger

Key Features

• Universal AA/AAA Compatibility: One charger for all of your AA and AAA rechargeables — 1.5V li-ion and 1.2V NiMH cells in any combination across four independent slots, from multiple brands.
• 4 x 0.5A Independent Channel Charging: Four slots, each with its own 0.5A charging circuit — four XTAR 1.5V AA 4150mWh batteries fully charged in 2.9 hours, four 1.2V NiMH AA 2500mAh in about 6 hours.
• Auto Battery Detection with Smart Charging: Drop a battery in and the L4 figures out what it is and how to charge it best — TC-CC-CV for 1.5V li-ion, XTAR's proprietary method for NiMH — resulting in faster charges, lower temperatures, and cleaner cut-off.
• Six Built-In Safety Protections: Reverse polarity, over-current, over-voltage, over-charge, short-circuit, dry battery detection, and overtime charging protection are all built in — so you can plug in and walk away with confidence.
• Over-Discharged Battery Revival & LED Status Indicators: Brings over-discharged batteries back to life that other chargers would skip, with per-slot LED indicators keeping you informed throughout the entire charge cycle.

Overview

The XTAR L4 is the one charger you need if your household runs on AA and AAA rechargeables. It handles 1.5V li-ion and 1.2V NiMH cells across all four slots simultaneously — mix and match brands and chemistries without a second thought. Powered by USB-C at 5V 2A, it delivers independent 0.5A charging to each slot and automatically identifies the battery type upon insertion, selecting the right charging method for each cell. The TC-CC-CV approach for li-ion cells and XTAR's NiMH control technology both prioritize speed, precise termination, and lower heat compared to standard charging methods. It can also wake up over-discharged batteries that most chargers would refuse to touch. The hollow-out design helps dissipate heat and makes loading and unloading batteries quick and easy. Comes with a USB-A to USB-C cable and user manual.
