Commitment to Rechargeable Batteries: Why HW Developed Them HW's commitment to developing rechargeable batteries stems from several key advantages they offer over traditional options. Lithium batteries can be charged and discharged over 1,000 times, significantly reducing long-term costs. Additionally, they do not contain harmful metals such as lead, mercury, or cadmium, making them a more environmentally friendly choice. Lithium batteries also provide stable voltage, ensuring consistent operation of connected devices. Furthermore, they can output higher currents to meet the demands of high-performance equipment. Recycling these batteries is an important way to conserve energy and promote sustainable development.

Reliable and Long-Lasting Batteries HW's 3.7V USB Rechargeable 3500mAh Lithium Batteries offer a range of benefits:

Constant Voltage: Maintains a consistent 3.7V voltage until the battery is fully depleted, ensuring stable device performance. Large Real Capacity: The 3500mAh capacity provides long-lasting power and reliable operation. No Memory Effects: Lithium batteries are not subject to memory effects, allowing them to be charged regardless of their current state of depletion. Advanced Safety Features: Integrated protection against overcharging, overdischarging, overvoltage, overcurrent, overheating, and short circuits, ensuring complete safety for connected devices.

Detailed Battery Specifications Capacity: 3500mAh (13000mWh) Voltage: 3.7V Size: 18.5mm x 70mm (length) Battery Type: Lithium Charge Cycles: 1,200 Charging Method: USB direct (use 5V/2A charging adapter) Applications: LED flashlights, headlamps, high-current devices

Note: This battery has a bottom-top design and is slightly longer (70mm) than a standard 3.7V battery due to its higher capacity. Please ensure your device is compatible with this size.

Reliable True Capacity and Convenient Charging HW's 3.7V 18mm Rechargeable Batteries provide a genuine 3500mAh capacity, ensuring long-lasting performance and reusability. Some batteries claiming higher capacities often fall short of their advertised specifications.

The built-in micro-USB port allows easy charging using the included 2-in-1 USB cable, without the need for a separate battery charger. Simply plug the battery into any USB port, anywhere, and enjoy over 1,200 charge cycles. This eco-friendly solution saves money and reduces environmental impact.

Safety Assurance and High Performance HW's 3.7V Li-ion Batteries feature an integrated safety circuit that protects against overcharging, overdischarging, short-circuits, and overheating, ensuring complete safety for your devices.

With a 3500mAh capacity and stable 3.7V output voltage, these batteries provide high performance and long-lasting power, making them an excellent replacement for devices that require frequent use.

Environmentally Friendly Rechargeable Batteries As a dedicated battery manufacturer, HW prioritizes the research and development of efficient, energy-saving rechargeable batteries. Compared to alkaline batteries, HW's rechargeable options offer over 1,200 charge cycles, low self-discharge, and constant voltage, providing a more stable power supply for your devices. By embracing recyclable charging, you can save money and reduce environmental pollution.

Note: The batteries are pre-charged to 50-60% capacity. For optimal performance, please fully charge the batteries when you receive them, as they may achieve their best performance after 3-5 charge-discharge cycles.
