Product Description:
The HIBATT 10440 is a premium lithium iron phosphate (LiFePO4) battery engineered for high safety and ultra-long cycle life. This 2pcs bundle delivers a reliable 220mAh capacity, a stable 3.2V output, and an outstanding 2000+ cycle lifespan. With a physical size nearly identical to a standard AAA battery (10.3mm x 44.8mm), it fits seamlessly into compact devices, but with a 3.2V output—more than double the voltage of a standard AAA.
Important Safety Warning:
While this battery shares the same physical dimensions as a standard AAA battery, it operates at 3.2V, NOT 1.2V or 1.5V. Do NOT use it in devices designed for standard AA/AAA batteries (such as remote controls, clocks, or standard toys), as this will permanently damage your device. It is strictly designed for devices that explicitly support 3.2V or 10440 batteries, such as certain solar lights, mini flashlights, and specialized sensors.

Frequently Asked Questions (FAQ):
Q1: Can I use this battery as a replacement for a standard AAA battery?
A1: NO. Please read the important warning above! While the physical size is similar to an AAA battery, the voltage is 3.2V, which is more than double the voltage of a standard AAA (1.5V) or Ni-MH (1.2V). Using this battery in a standard AAA device will instantly damage your device. It is ONLY compatible with devices specifically designed for 3.2V or 10440 batteries.
Q2: What is the cycle life of this battery?
A2: This LiFePO4 battery is designed for over 2000 full recharge cycles, providing exceptional long-term value and significantly reducing replacement costs.
Q3: What is the advantage of the LiFePO4 chemistry?
A3: LiFePO4 (Lithium Iron Phosphate) offers superior thermal stability, a much longer cycle life (2000+ cycles vs 300-500 cycles), and enhanced safety compared to standard Li-ion batteries. It is much less prone to overheating or fire.
Q4: What is the difference between this Button Top and a Flat Top?
A4: This battery features a Button Top (protruding positive terminal) which ensures a secure connection in devices with recessed battery contacts. If your device requires a flat contact, you will need a Flat Top version.
Q5: What kind of charger should I use for this battery?
A5: You must use a charger specifically designed for 3.2V LiFePO4 batteries with a 3.65V cut-off voltage. Do not use a standard 3.7V/4.2V Li-ion charger or a standard AAA Ni-MH charger.
