【Product Description】
The “Platinum-Grade” Power Bundle for Your High-End Devices!
Are you tired of your smart locks, game controllers, or digital cameras losing power too quickly? Stop buying disposable batteries and switch to the XTAR L4 Pro Smart Charger Kit with 4x AAA 1.5V 1200mWh Li-ion Batteries.
The included batteries feature constant 1.5V output throughout their entire discharge cycle. Unlike traditional NiMH batteries that drop to 1.2V, these Li-ion cells deliver a rock-solid 1.5V voltage until they are completely depleted, ensuring your high-demand electronics perform flawlessly.
The XTAR L4 Pro is one of the few chargers on the market specifically designed to safely and automatically handle 1.5V Li-ion batteries. Featuring a crystal-clear LCD display, the L4 Pro monitors real-time charging status. With its DisCHG (Capacity Test) mode, you can test the true capacity of your cells, and the Refresh Mode intelligently revives tired NiMH batteries.
( IMPORTANT: This bundle includes the charger, Type-C cable, and 4x AAA 1.5V 1200mWh Li-ion batteries. Wall adapter is sold separately / depending on variant.)

【Frequently Asked Questions (FAQ)】
Q1: Are the included 1.5V Li-ion batteries pre-charged?
A1: Yes, the included AAA 1.5V Li-ion batteries come with a partial factory charge, so they are ready to use immediately. For optimal performance, we recommend giving them a full charge cycle using the L4 Pro charger upon receipt.
Q2: What is the advantage of 1.5V constant voltage over 1.2V NiMH?
A2: Standard NiMH batteries start at 1.5V but drop to 1.2V very quickly. Many sensitive devices (like smart locks and cameras) will shut down or malfunction when the voltage drops below 1.3V. 1.5V Li-ion batteries maintain their output until they are completely dead, giving you 100% of the power you paid for.
Q3: Why is it labeled as 1200mWh and not 800mAh?
A3: mWh (milliwatt-hours) measures total energy. Since this battery has a constant 1.5V output, the calculation is: Energy (mWh) ÷ Voltage (V) = Capacity (mAh). Therefore, 1200mWh ÷ 1.5V = 800mAh. This is a standard industry calculation.
Q4: Can I charge the included AAA batteries and my 1.2V NiMH batteries at the same time?
A4: Absolutely! The XTAR L4 Pro features 4 independent slots with automatic detection. You can charge a 1.5V Li-ion AAA battery and a 1.2V NiMH AAA battery simultaneously. The charger will apply the correct charging algorithm to each slot.
Q5: Do I need to buy a special adapter for it?
A5: No, you can simply plug the included Type-C cable into any 5V/2A USB wall charger you already have at home (like your phone charger). If you need a high-quality QC3.0 wall adapter, it is available in our other variants.
