18650 Sanyo UR18650ZY Lithium-Ion Battery (Low Profile Button)
 

The Sanyo UR18650ZY Lithium-Ion Battery is a high-quality, rechargeable energy storage solution that has been engineered to deliver reliable and consistent performance across various demanding applications. Known for its excellent build quality and robust design, this battery is especially popular among enthusiasts, professionals, and industries that require a dependable power source with the right balance of energy density, longevity, and safety features.

 
Technical Specifications and Chemistry

Voltage and Capacity

The Sanyo UR18650ZY operates with a nominal voltage of 3.6 Volts, which is standard for many lithium-ion cells. This voltage rating is carefully balanced with the battery’s capacity of 2600 mAh, ensuring it delivers an efficient performance that supports both high-drain and continuous power applications. This combination offers a stable energy output ideal for tasks that demand reliability over prolonged periods.

Furthermore, the battery is capable of reaching a maximum voltage of 4.2 Volts when fully charged. A built-in cutoff mechanism is set at 2.75 Volts to protect the cell from over-discharge—a situation that can lead to reduced battery performance or even cell damage. This particular feature is crucial for maintaining the longevity and operational stability of the battery, ensuring that even when the battery is used repeatedly or in fluctuating conditions, its performance remains consistent and its lifespan prolonged.

Lithium-Ion Chemistry

At the heart of the UR18650ZY battery lies its advanced lithium-ion (Li-Ion) chemistry. Lithium-ion batteries are renowned for their high energy density, which allows more energy to be stored in a smaller, lighter package compared to older battery chemistries such as nickel-cadmium. This is particularly beneficial in applications where weight and space are critical constraints.

Lithium-ion cells do not suffer from the memory effect that was once a common issue with rechargeable batteries like nickel-cadmium (NiCd). This absence of memory effect means that the Sanyo UR18650ZY can be charged at any time without necessitating a full discharge cycle beforehand, offering convenience and flexibility that appeals to both casual users and professionals alike.

 
Design and Physical Attributes

Low Profile Button Top Terminal

One of the defining physical features of the Sanyo UR18650ZY is its low profile button top terminal. This design element is not just about aesthetics; it has practical implications. The button top terminal configuration is specifically designed to be compatible with a wide array of battery holders and devices. By having this standardized design, the battery is more versatile, fitting seamlessly into many portable electronic devices, flashlights, power tools, and other equipment that require a secure and reliable connection to the power source.

Dimensional Specifications

The battery's well-thought-out design includes precise measurements to ensure both compatibility and ease of integration:

Diameter: Approximately 18.47 millimeters
Length (Button Top): Roughly 66.03 millimeters
These dimensions are consistent with industry standards for 18650 cells, making the UR18650ZY a popular replacement or upgrade option for devices that rely on a specific form factor.

Weight Considerations

At around 46 grams, the Sanyo UR18650ZY strikes an excellent balance between capacity and portability. The relatively light weight of this battery ensures that it doesn’t add unnecessary bulk to devices, which is particularly important for portable and handheld applications where every gram counts.

 
Performance Under Load

Maximum Continuous Discharge Capability

One of the standout features of this battery is its ability to handle moderate power demands with ease. With a maximum continuous discharge capacity of 5 Amps, the UR18650ZY is engineered to supply consistent power even under high-drain conditions. This robust performance is particularly valuable in applications that experience intermittent peaks in power demand, such as in advanced flashlights, vaping devices, and various power tools. This discharge capacity not only ensures that devices function optimally but also contributes to the battery’s overall durability and resilience under stress.

 
Safety Features and Longevity

Over-Discharge Protection

To safeguard the battery from potential damage due to over-discharge, the Sanyo UR18650ZY is equipped with a built-in cutoff voltage mechanism set at 2.75 Volts. Over-discharging a lithium-ion cell can lead to a permanent reduction in capacity or even render the battery unusable. By preventing the voltage from dropping too low, this feature significantly enhances the battery's long-term reliability and operational safety, ensuring that users enjoy a longer service life with fewer performance issues over time.

No Memory Effect and Long Storage Life

Another critical advantage of the UR18650ZY is that it is free from the memory effect—a phenomenon that can decrease the overall capacity of rechargeable batteries when they are repeatedly charged without being fully discharged. The absence of this effect means that users can recharge the battery at their convenience without having to worry about sacrificing capacity. Furthermore, the battery boasts a long storage life, making it an ideal choice for scenarios where the battery may not be in constant use. Whether as a backup power source or in devices that are used intermittently, the long storage life ensures that the battery remains reliable even during extended periods of inactivity.
