A2: Absolutely. It is built with a high-quality upgraded steel shell and a reinforced sealing process to effectively prevent leakage. The battery is manufactured under strict quality control by Delipow, a brand with over 24 years of expertise.
Q3: Can this battery be used in high-drain devices?
A3: Yes. Its optimized design provides low internal resistance and strong discharge performance, making it an excellent choice for high-drain devices such as LED flashlights and electric power tools.
Q4: Can I use this battery as a replacement for a standard AA battery?
A4: No, it cannot. While its height (50mm) is the same as a standard AA battery, the 16500 has a larger diameter (16mm) than a standard AA (14mm). It is only compatible with devices specifically designed for 16500 batteries. Please check your device's battery compartment size.
Q5: What kind of charger should I use for this battery?
A5: You must use a charger specifically designed to charge 3.7V lithium-ion batteries (such as a 16500 or 18650 charger). Do not attempt to charge it in a standard AA/AAA Ni-MH charger, as it will not cut off at the correct voltage and is extremely dangerous.
