Product Description:
Power your demanding applications with the Genuine Sanyo UR14650R 3.7V 1050mAh High-Drain Li-ion Battery (2-Pack). This premium Japanese cylindrical cell is engineered specifically for high-power devices, offering a rare 10A Max Continuous Discharge in the 14650 form factor. Whether you are upgrading a cordless robot vacuum, repairing a high-lumen flashlight, or building a custom power tool pack, this battery delivers unmatched burst power and reliability.
To meet different installation needs, we offer two versatile versions in this single listing:
-
Flat Top (Bare Cell): Designed for standard spring-loaded battery compartments or for custom spot-welding into battery packs.
-
With Pre-Welded Solder Tabs: Features strong nickel tabs pre-welded to both terminals, ready for direct soldering onto motherboard PCBs.
With a robust 1050mAh capacity and ultra-low internal resistance, this Sanyo cell provides stable voltage even under heavy load, ensuring your equipment performs at its peak.
CRITICAL INSTALLATION WARNINGS:
-
Size Alert: This is a 14650 battery. It is 14mm in diameter and 65mm in height, which is significantly longer than standard 14500 batteries (48-50mm). Please verify your device's battery compartment depth before ordering.
-
High-Drain Alert: This is a 10A Max Discharge cell. It is designed for high-power devices. DO NOT use it in low-power devices, as without proper cut-off circuits, it may lead to excessive discharge and battery damage.
-
Tab Version Alert: The "With Solder Tabs" version requires a soldering iron and is NOT for spring-loaded flashlight compartments.

FAQ:
Q: What is the difference between the two variations in this listing?
A: The "Flat Top" version is a bare cell without any tabs. It is meant to be used in spring-loaded flashlight compartments or for spot-welding into a custom battery pack. The "With Solder Tabs" version has nickel tabs pre-welded to the terminals for direct soldering onto the circuit board of your device. Choose the one that matches your project.
Q: Is this battery compatible with my 14500 device?
A: No. The 14650 is 65mm tall, while a standard 14500 is only 48-50mm tall. They are physically NOT interchangeable.
Q: Can I use this 10A battery in my low-power electronics?
A: Not recommended. High-drain batteries are designed for high-current applications. Using a 10A battery in a low-drain device (like a low-power clock or sensor) might force the battery to discharge completely because the device won't cut off the power.
Q: I chose the "With Solder Tabs" version. Can I put it in a spring-loaded flashlight?
A: No. The attached metal tabs will short-circuit or get stuck in a spring-loaded compartment. It must be soldered onto a PCB.
Q: Is this battery protected (with a PCB)?
A: No. This is a high-drain unprotected cell. It relies on your high-power device's built-in over-discharge protection circuit.
