USB Rechargeable Lithium Batteries for Flashlights, Headlamps, RC Cars - 2 Pack

Product Description

Why is HW committed to developing rechargeable batteries?

HW is committed to developing rechargeable batteries because they offer several advantages. Firstly, lithium batteries can be charged and discharged multiple times, with over 1000 cycles of use, which can save costs. Additionally, lithium batteries do not contain harmful metal elements such as lead, mercury, cadmium, etc. Moreover, lithium batteries can provide stable voltage to ensure the stable operation of equipment and output higher currents to meet the needs of high current performance devices. Lastly, recycling rechargeable batteries is an important way to save energy and achieve sustainable development.

Reliable and Long-lasting Battery

The HW 3.7V USB Rechargeable 3500mAh Lithium Battery is a reliable and long-lasting battery. It maintains a constant voltage of 3.7V until the whole cell is depleted, ensuring stable operation of devices. With a large real capacity of 3500mAh, this battery is long-lasting and reliable. It also has no memory effects, meaning it can be charged regardless of whether it is fully or partially drained. The battery also provides more safety protection, supporting over-charged, over-discharged, over-voltage, over-current, over-heat, and short circuit protection.

HW USB 3.7V 18M Lithium Battery

The HW USB 3.7V 18M Lithium Battery has a capacity of 3500mAh (13000mWh) and a voltage of 3.7V. Its size is 18.5mm x 70mm in length, and it is made of lithium. It can be charged up to 1200 times and can be charged via USB using a 5V/2A charging adapter. This battery is suitable for applications such as LED flashlights, headlamps, and high current devices. Please note that this battery is of the bottom top type and its size is slightly longer than a regular 3.7V battery due to its higher capacity. It is important to check if your device is compatible with this battery.

HW USB Rechargeable Batteries

HW USB rechargeable batteries are 3.7V lithium batteries used for flashlights, toys, headlamps, and other household devices. However, please note that this product does NOT include restricted lithium-ion standalone batteries such as 14500, 16340, 18650, 20700, 21700, and 26650.

Reliable True Capacity 3500 mAh

The HW 3.7V 18mm Rechargeable Battery provides an actual capacity of 3500mAh, making it a long-lasting and reusable battery. It is important to note that batteries claiming to exceed 5000mAh will have much lower actual capacities.

Built-in micro USB port for easy charging

This battery features a built-in micro USB port, making it easy to charge with the included 2-in-1 USB cable. It does not require an additional battery charger. Simply plug it into any USB port at any time and anywhere. With over 1200 cycles, this battery is eco-friendly and saves money.

Safety Assurance

The HW 3.7V Li-ion batteries have built-in integrated safety circuits that protect the battery from over-charge, over-discharge, short-circuit, and over-heat. This ensures complete safety during the battery charging process.

High performance

The HW 3.7V Li-ion batteries with a capacity of 3500mAh support a stable 3.7volt output voltage. This makes devices work more stably and last longer, making these batteries great replacements for frequently used devices.

Environmentally Friendly Rechargeable 3.7v Battery

As a professional battery manufacturer, HW is dedicated to developing efficient and energy-saving rechargeable batteries. Compared to alkaline batteries, rechargeable batteries have over 1200 cycles, low self-discharge, and provide constant voltage, resulting in a more stable power supply to devices. Additionally, these rechargeable batteries can be recycled, saving expenses and reducing environmental pollution.

Note: The batteries are only precharged to 50%-60% of capacity. It is recommended to fully charge the batteries upon receipt. New batteries can achieve the best performance after undergoing 3-5 cycles of charge and discharge.
