XTAR R03/AAA 1,5 V Li-ion-accu's (4-pack, 1620 mWh, 1000 mAh)

Constant 1.5V output until depletion meets 1200-cycle longevity in the XTAR R03/AAA Li-ion batteries. Each cell packs 1620mWh of energy (1000mAh capacity) with a built-in protection circuit, delivering reliable power for high-drain devices without the voltage sag of NiMH.

Overview

The XTAR R03/AAA is a lithium-ion rechargeable battery engineered for consistent performance. Unlike traditional NiMH cells that drop to 1.2V, these batteries maintain a steady 1.5V throughout discharge, ensuring your devices operate at full power until the battery is depleted. With a low self-discharge rate, they retain 80% charge after a year of storage, making them ideal for emergency kits or infrequently used gadgets.

What stands out

• Stable 1.5V output for consistent device performance
• Up to 1200 charge cycles for long-term value
• Built-in protection against over-charge, over-discharge, short-circuit, and over-current
• Low self-discharge: 80% capacity after 12 months
• High-drain capability with 2A max continuous discharge
• Compact AAA size fits most standard devices
