XTAR R6 AA 1.5V Li-ion Rechargeable Batteries 2700mWh 4-Pack

Constant 1.5V output until fully depleted — the XTAR R6 AA Li-ion batteries deliver 2700mWh of energy with a built-in voltage regulator, ensuring your devices perform at their peak from first use to last. Unlike NiMH cells that sag to 1.2V, these lithium-ion batteries maintain a rock-solid 1.5V, making them ideal for high-drain gadgets like wireless mice, keyboards, and flashlights.

Overview

The XTAR R6 is a rechargeable AA (R6) battery built on lithium-ion chemistry. Each cell stores 2700 milliwatt-hours of energy, equivalent to roughly 1800mAh at a constant 1.5V. This 4-pack includes four batteries, ready to power your everyday electronics. A dedicated Li-ion charger is required (not included) — do not charge in NiMH or alkaline chargers.

What stands out

• Constant 1.5V output — no voltage drop as the battery discharges
• 2700mWh energy capacity — long runtime for high-drain devices
• Up to 1200 charge cycles — cost-effective and eco-friendly
• Comprehensive protection: over-charge, over-discharge, short-circuit, over-current, reverse polarity
• Mercury, cadmium, and lead free — safe for household use
