Product Description:
Meet the Delipow DLP-659, a practical 2-slot LED indicator charger bundled with high-performance 10400 3.7V 320mAh flat top Li-ion batteries in a distinct green finish. This compact kit is specifically designed for mini flashlights and specialty devices that require the short 10400 battery format. Choose from 2-Pack or 4-Pack options to perfectly suit your usage needs.
The DLP-659 features intuitive Red-to-Green LED indicator lights for each of the 2 independent slots. While charging, the light glows Red; once the battery reaches full charge, it automatically switches to Green. Powered via a standard USB port (DC 5V 1-2A), the charger delivers a rapid 500mA×2 charging current, ensuring fast and efficient recharging. The built-in smart chip provides a precise cut-off voltage of 4.2V, automatically stopping the process to prevent overcharging and extend battery lifespan. The spring-loaded slots are universally designed to support a wide range of 3.6V/3.7V Li-ion batteries, including 10440, 18650, 14500, 16340, and more.

Frequently Asked Questions (FAQ):
Q1: Can I use this 10400 battery as a replacement for a standard AAA battery?
A1: NO. Please exercise extreme caution! While the 10400 shares similar physical dimensions to a standard AAA battery, it operates at 3.7V. Using a 3.7V battery in a device designed for 1.2V or 1.5V (like standard remotes, clocks, or toys) will instantly damage or destroy the device. It is only compatible with devices explicitly specified for 10400/10440 or 3.7V power.
Q2: What is the advantage of the 500mA×2 charging current?
A2: 500mA is a high charging current for 10400 batteries. It significantly reduces charging time. A 320mAh battery can typically reach a full charge in about 1 hour, ensuring your devices are ready to use quickly.
Q3: Can I charge two different-sized batteries at the same time?
A3: Yes! The DLP-659 features 2 independent slots with spring-loaded contacts. You can freely mix and charge different compatible 3.6V/3.7V Li-ion batteries simultaneously without any issues.
Q4: How do I know when the battery is fully charged?
A4: It is very simple. The DLP-659 features an independent Red-to-Green LED light for each slot. While charging, the light glows Red. Once the battery reaches the precise 4.2V cut-off voltage, the light automatically turns Green, indicating it is ready to use.
Q5: What kind of charger should I use if I only buy the battery?
A5: You must use a charger specifically designed to charge 3.7V Li-ion batteries, such as the included DLP-659. Do not attempt to charge it in a standard AA/AAA Ni-MH charger, as it will not cut off at the correct voltage.
