Pack of 2 AA Rechargeable Lithium Ion Battery - USB Rechargeable Lithium Battery

The Pack of 2 LDLDCHI 1.5V Lithium-ion AA Rechargeable Battery is a high-performance, eco-friendly power solution designed to replace traditional alkaline batteries in demanding devices. Unlike standard rechargeables, it maintains a constant 1.5V output for superior performance. 🔋✨

⚡ Power & Performance

• Constant 1.5V Output: Provides steady voltage until the battery is empty, preventing "weak" performance in devices like motorized toys or flashes.
• High Energy Density: Boasts a 3400mWh energy capacity, equivalent to a 2000mAh rating.
• Chemistry: Uses advanced LiNiMnCoO2 (NMC) cathode materials for a stable and efficient discharge.
• Discharge Rate: Supports a continuous discharge rate of 2A, making it suitable for high-drain electronics.

🔄 Longevity & Charging

• Cycle Life: Engineered for up to 1000 recharge cycles, significantly reducing environmental waste compared to single-use batteries.
• Charging Input: Optimized for a charging ratio of 5V / 350mA.
• Operating Range: Works reliably in extreme temperatures ranging from -20°C to 60°C.

📏 Physical & Safety Specs

• Standard Size: Fits all AA (14500) battery compartments with dimensions of 14 x 50 mm.
• Lightweight: Each cell weighs only 20g, which is lighter than many NiMH rechargeable batteries.
• Safety Certified: Fully compliant with CE, RoHS, MSDS, UN38.3, and IEC 62133 standards for international safety and shipping.

🛠️ Versatile Applications

• Toys & Gadgets: Perfect for RC cars and remote-controlled drones.
• Home Appliances: Ideal for smart door locks, blood pressure monitors, and electric toothbrushes.
• Consumer Electronics: Great for high-end computer mice, keyboards, and camera gear.

💡 Shop Note

If you're tired of your devices slowing down as the battery drains, these are a total game-changer. Because they are Lithium-ion, they stay at a full 1.5V until they are empty, unlike old-school rechargeables that drop to 1.2V. You get 'fresh battery' power for the entire charge! Just a tip: please use a dedicated Lithium 1.5V charger to keep these running for all 1000 cycles."
