Sobre este producto

Long-Lasting Power & High Capacity: With 4100mWh energy , these batteries match alkaline battery performance (e.g., similar to Nanfu). A single charge powers high-drain devices such as flashlights, toys, and smart home gadgets for extended periods, reducing frequent replacements to avoid damaging your device
2500+ Recharge Cycles & Cost Savings: Engineered for over 2500 charge cycles with no memory effect, these reusable batteries save money versus disposables. Charge anytime using the included Type-C cable (gift accessory), and enjoy reliable power for years—ideal for eco-conscious users
Enhanced Safety & Low Power Alert: Built-in PCB protection prevents short circuits, overcharging, and overheating. Plus, a unique low-power warning system alerts you via alarm when energy is low, avoiding unexpected shutdowns in essential devices like door locks
Dual-Color LED Charging Indicators: Features intuitive green/red LED lights, blinking green during charging, solid green when fully charged. Red light alerts for abnormal charging status, ensuring real-time monitoring without guesswork
Full Stainless Steel Construction: Battery casing and core components use premium 304 stainless steel, providing superior corrosion resistance, oxidation prevention, and 100% leak-proof safety. Outlasts plastic-shell batteries in humid or high-temperature environments
USB Convenience & Friendly Design: Charge effortlessly via USB using adapters, power banks, or laptops with the included Type-C cable. Stainless steel 304 construction resists corrosion and leaks, helping reduce landfill waste by thousands of batteries annually
Variable Voltage with Smart Alarm Protection: our lithium AA batteries feature variable voltage technology. They maintain stable 1.5V output and alert you with an audible alarm before depletion, ensuring uninterrupted use in critical devices like smart door locks and security systems
