USB Rechargeable Lithium Batteries, Reliable True 3500mAh (13000mWh) 18m Long-Lasting High Performance Battery (2 Pack) for Flashlights, Headlamps, RC Cars

Product Description Why is HW committed to developing rechargeable batteries?

HW is committed to developing rechargeable batteries because lithium batteries offer numerous benefits. They can be charged and discharged over 1000 times, saving costs in the long run and reducing waste. Additionally, lithium batteries do not contain harmful metal elements such as lead, mercury, and cadmium. They also provide stable voltage and can output higher currents to meet the needs of high-performance devices. Recycling rechargeable batteries is also an important way to save energy and achieve sustainable development.

Reliable and Long-lasting Battery HW offers the 3.7V USB Rechargeable 3500mAh Lithium Battery, which provides a constant voltage of 3.7V until the whole cell is depleted, ensuring stable operation. With a large real capacity of 3500mAh, this battery has no memory effects, supports various safety protections, and has a long lifespan of 1200 charge cycles. It is suitable for use in LED flashlights, headlamps, and other high current devices.

HW USB 3.7V 18M Lithium Battery This lithium battery has a capacity of 3500mAh (13000mWh) and a voltage of 3.7V. Its size is 18.5mm x 70mm, slightly larger than a regular 3.7V battery due to its higher capacity. The battery cell is made of lithium and can be charged directly using a USB (5V/2A charging adapter). It is suitable for use in LED flashlights, headlamps, and high current devices.

HW USB Rechargeable Batteries HW’s 3.7V lithium batteries are suitable for use in flashlights, toys, headlamps, and other household devices. However, they are not sold with restricted lithium-ion standalone batteries, such as 14500, 16340, 18650, 20700, 21700, and 26650 types.

Key Features The HW 3.7V 18mm Rechargeable Battery offers a reliable true capacity of 3500mAh, with a built-in micro USB port for easy charging. It also comes with integrated safety circuits for protection and provides stable 3.7V output voltage for high performance.

Environmentally Friendly Rechargeable 3.7V Battery HW’s rechargeable batteries are designed to be efficient and energy-saving, with over 1200 cycles, low self-discharge, and constant voltage. This makes them a more environmentally friendly and cost-effective option than traditional alkaline batteries.

Note: The batteries are precharged to 50%-60% of their capacity. It is recommended to fully charge the batteries upon receiving them and to cycle them through 3-5 charges and discharges for optimal performance.
