Product Description:
Upgrade your outdoor and household devices with the IFR18500 3.2V 1500mAh LiFePO4 Rechargeable Battery (2-Pack). Unlike standard 3.7V lithium-ion cells, this premium battery utilizes LiFePO4 (Lithium Iron Phosphate) chemistry, offering superior safety, thermal stability, and an incredible 2000+ recharge cycle lifespan.
With a high capacity of 1500mAh, it provides long-lasting, reliable 3.2V power for solar garden lights, hair clippers, trimmers, and various small electronics. We offer this versatile cell in two terminal styles within this listing, allowing you to choose the exact fit for your device: Button Top (approx. 52mm) and Flat Top (approx. 50mm).
CRITICAL VOLTAGE & CHEMISTRY WARNING:
This is a 3.2V LiFePO4 (Lithium Iron Phosphate) battery. It is NOT a standard 3.7V lithium-ion battery. It is specifically engineered for devices that require a 3.2V power platform (such as many solar lighting systems and specific cordless clippers). DO NOT use this battery in devices designed for 3.7V 18500 cells, as the lower voltage may trigger low-voltage protection or cause the device to operate weakly. Please check your original battery's voltage before ordering.
Key Features:
Advanced LiFePO4 Chemistry: Offers unmatched safety (non-combustible), excellent thermal stability, and a stunning 2000+ cycle lifespan – lasting up to 4 times longer than standard lithium-ion batteries.
High Capacity 1500mAh: Provides extended runtime and reliable power for outdoor solar lights and grooming tools.
Dual Terminal Options: Choose between the Button Top (52mm) for spring-loaded contacts or the Flat Top (50mm) for flat contact plates and custom spot-welding.
Stable 3.2V Output: Delivers consistent voltage for devices specifically designed for the 3.2V platform.
Convenient 2-Pack: Comes with two matched batteries, perfect for keeping a spare or powering devices that require a pair.

FAQ:
Q: What is the advantage of LiFePO4 over standard 3.7V lithium-ion batteries?
A: LiFePO4 offers significantly better safety (it won't catch fire easily), much longer cycle life (2000+ vs 500), and better performance in outdoor temperature variations.
Q: Why is the voltage 3.2V instead of 3.7V?
A: 3.2V is the nominal voltage of LiFePO4 chemistry. It is designed for devices specifically built for the 3.2V platform, such as solar lights and some specific clippers. Using this in a 3.7V device will either trigger low-voltage protection or the device will run weakly.
Q: Is this battery compatible with my 3.7V 18500 device?
A: No. This is a 3.2V battery. If your device requires 3.7V, this will provide insufficient voltage.
Q: How do I choose between Button Top and Flat Top?
A: If your device has a spring-loaded battery compartment (most flashlights and clippers), choose the Button Top (52mm). If your device uses flat metal contacts or you plan to spot-weld it into a pack, choose the Flat Top (50mm).
Q: Is this battery protected (with a built-in PCB)?
A: No, this is an unprotected LiFePO4 cell. It relies on your device's built-in protection circuit.
Q: How long does it take to fully charge this 1500mAh battery?
A: Using a dedicated 3.2V LiFePO4 charger at a 1A rate, it will take approximately 1.5 to 2 hours.
