1.5V AA Battery & Charger

1.5V AA Battery & Charger – Constant Voltage Li-ion Technology + USB Convenient Charging, Stable 1.5V Output High-Performance Combo

Welcome to our 1.5V AA Battery & Charger collection. Products in this category feature an integrated design combining a lithium-ion cell with a precision step-down voltage regulator, delivering a constant 1.5V output throughout the entire discharge cycle—all within the standard AA form factor. Unlike alkaline batteries whose voltage steadily declines, or NiMH cells with a nominal 1.2V, 1.5V regulated Li-ion AA batteries maintain a rock-steady 1.5V output for over 95% of their discharge cycle, ensuring your device receives full power from start to finish. Most models also integrate a USB-C or Micro-USB charging port, eliminating the need for a dedicated charger. This collection provides a one-stop solution with batteries and charging accessories, making it the ideal power upgrade for premium high-lumen flashlights, wireless microphones, electric toys, digital cameras, smart door locks, medical devices, and any voltage-sensitive professional equipment.

Core Advantages of 1.5V Regulated Li-ion AA Batteries

• Constant 1.5V Output – Consistent Performance Throughout: A built-in smart step-down circuit precisely converts the internal Li-ion cell's 3.7V to a regulated 1.5V output that holds steady until nearly depleted. No more dimming flashlights, sluggish motors, or unstable signals as the battery drains.
• USB Convenient Charging – No Dedicated Charger Needed: Most models feature an integrated USB-C or Micro-USB charging port. Recharge anywhere using a phone charger, power bank, or laptop USB port. Travel with just one cable—leave the bulky dedicated charger at home.
• High Energy Density, Lightweight Design: Weighing only 18g–22g per cell—20%–30% lighter than NiMH AA (~26g–30g). The weight savings are especially noticeable in handheld devices or equipment requiring multiple batteries.
• Ultra-Low Self-Discharge – Always Ready: Monthly self-discharge is just 2–3%. Cells retain ample charge after months—even a year—of storage, making them perfect for emergency backup and intermittently used devices.
• 1,000+ Cycles – Economical & Eco-Friendly: Supports 1,000+ charge/discharge cycles, replacing hundreds of disposable alkaline batteries over its lifetime. Long-term cost is minimal, and battery waste is drastically reduced.
• Wide Operating Temperature Range: Reliable operation from -20°C to 60°C during discharge—dependable even in winter outdoor conditions.

Core Advantages of Companion Charging Accessories

• Multi-Bay Charging Cables: Charge 2–4 1.5V Li-ion AA batteries simultaneously with independent LED indicators showing charging status.
• Smart Charging Management: Built-in constant current/constant voltage charging IC with auto-termination prevents overcharging and preserves battery lifespan.
• Multi-Protocol Compatibility: Compatible with USB-A / USB-C inputs and supports QC/PD fast charging adapters for more efficient charging.
• Magnetic / Snap-On Connection: Charging cables feature magnetic or snap-on connectors for secure attachment and plug-and-play convenience.

How to Choose the Right 1.5V AA Battery & Charger?

⚠️ 1.5V Regulated Li-ion AA Battery Safety Guidelines

• Do Not Mix with Alkaline or NiMH Batteries: While the output voltage is 1.5V, the internal circuitry differs fundamentally. Do not mix these batteries with alkaline or NiMH cells in the same device.
• Charge Only via Integrated USB Port: Use the supplied USB cable or a compliant USB cable to charge. Never attempt to charge these batteries in a NiMH or standard Li-ion bay charger.
• Avoid Over-Discharge: Recharge promptly when the device indicates low battery or performance noticeably drops. Built-in protection prevents deep discharge, but prolonged storage in a depleted state may shorten lifespan.
• Avoid Short Circuits and High Temperatures: Do not short the positive and negative terminals. Keep away from fire, heat sources, and humid environments.
• Long-Term Storage: Store at 50%–80% charge in a cool, dry location. Recharge every 6–12 months to maintain battery health.
• Recycle Responsibly: Dispose of used batteries at designated recycling facilities. Never discard in household trash or incinerate.
