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 difference between this 10400 and the standard 10440?
A2: This 10400 battery has a height of 40mm, which is 5mm shorter than a standard 10440 (45mm). It is designed specifically for ultra-compact mini flashlights that have shorter battery compartments and cannot fit the taller 10440 size.
Q3: What is the difference between Flat Top and Button Top?
A3: A Flat Top battery has a flat positive terminal, while a Button Top has a protruding nub. Please check your device's battery compartment carefully. If your device requires a protruding positive contact, you need a Button Top version; this product is Flat Top.
Q4: How long does it take to fully charge a 320mAh battery?
A4: Charging time depends on your specific Li-ion charger. Using a standard dedicated 10440/3.7V charger, it typically takes approximately 1 to 1.5 hours.
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 10440 or 14500 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.
