Frequently Asked Questions (FAQ):
Q1: What is the advantage of the pre-welded nickel tabs?
A1: The nickel tabs are already spot-welded to the battery terminals. This eliminates the need for expensive spot welding equipment. You can directly solder your wires to the nickel tabs using a standard soldering iron, making it easy to integrate into DIY projects.
Q2: Can I use this battery as a replacement for a standard AAA battery?
A2: NO. While the physical size is identical to an AAA battery, the voltage is 3.7V, which is significantly higher than 1.2V/1.5V batteries. Using this battery in a standard AAA device will instantly damage your device. It is ONLY compatible with devices specifically designed for 10440 or 3.7V power.
Q3: Does this battery have a built-in protection board?
A3: No. This is a bare cell without a built-in protection board. Please take extra care to avoid over-discharging or over-charging. We recommend using a smart charger with over-charge protection to ensure safety.
Q4: What kind of charger should I use for this battery?
A4: You must use a charger specifically designed for 3.6V/3.7V Li-ion batteries with a 4.2V cut-off voltage. Do not use a standard AAA Ni-MH charger. A smart charger with over-charge protection is highly recommended.
Q5: Is this battery suitable for high-drain devices?
A5: This battery is designed for medium-to-high drain compact devices such as mini flashlights and EDC gear. For extremely high-current devices, please check your device's amp requirements.
