What is the FDK CR14250SE 3V? A concise overview

The FDK CR14250SE 3V is a cylindrical primary lithium battery designed for devices that demand a stable 3-volt supply in a compact form factor. The model name itself signals several important attributes: the CR family denotes a primary (non-rechargeable) lithium chemistry, the 14250 indicates the physical size—14 mm in diameter and 25 mm in length—and the SE suffix denotes a specific product variant within FDK’s CR line. This combination makes the CR14250SE 3V a popular choice for memory back-up systems, remote sensors, medical devices, security gadgets, and other electronics that need dependable performance in a small package.

From an SEO and product-management perspective, the CR14250SE 3V benefits from being highly searchable in terms of both the exact model and the broader category. People search for terms like “FDK CR14250SE data sheet,” “CR14250SE 3V replacement,” and “CR14250SE battery life.” Aligning content around these phrases helps search engines connect user questions with the practical information they seek. In practice, you’ll often see this model discussed alongside other CR14250 family members and adjacent CR-series cells to compare size, voltage, and intended use.

Physical dimensions and electrical basics

Dimensions and electrical characteristics form the backbone of any battery interchange analysis. For the CR14250SE 3V, you should expect the following baseline facts, widely cited in product sheets and technical references:

• Diameter: 14 millimeters
• Length: 25 millimeters
• Nominal voltage: 3.0 volts
• Form factor: Cylindrical primary cell (non-rechargeable)
• Chemistry: Lithium-based chemistry common to CR-series cells (often Li/MnO2, with variations by model)

Because the CR14250SE 3V is a primary cell, it is designed to deliver energy without the option for recharge. This makes it especially suitable for devices that require a stable, long-lived power source without the complexity of recharging circuits. When you’re evaluating alternatives or backups, verifying that your device is compatible with a non-rechargeable 3V lithium cell is essential to avoid safety hazards or device-malfunction due to improper charging or voltage characteristics.

Chemistry and performance profile: what to expect

FDK’s CR-series power cells traditionally use lithium/manganese dioxide (Li/MnO2) chemistry, prized for high energy density, good shelf life, and wide operating temperature ranges. The SE variant of the CR14250 may incorporate a refined internal design or packaging that improves certain performance attributes, such as leakage resistance or terminal compatibility. While exact internal specifications (e.g., internal impedance, discharge curves at specific drain rates, or the precise capacity rating) are defined in the datasheet and may vary by production lot, several general performance characteristics apply:

• Discharge behavior: The CR14250SE 3V is designed to provide a relatively steady voltage output over its useful life, with a gradual decline as the chemical reaction proceeds. Devices with low to moderate drain tend to experience more stable voltage profiles.
• Self-discharge and shelf life: Lithium primary cells typically exhibit very low self-discharge rates, enabling long storage periods. A well-preserved CR14250SE can remain usable for many years when stored in appropriate conditions.
• Operating temperature: Standard operating ranges for CR-series cells span a broad range, but performance and capacity can be affected by temperature extremes. The safe design range should be checked in the datasheet for specific applications, especially medical or industrial deployments.

For engineers, the key takeaway is to consult the official FDK datasheet for exact capacity figures at a given discharge rate and operating temperature. Capacity is not a fixed, one-number figure; it depends on how quickly the device draws current. A device with a very low current draw may yield a higher effective capacity than one that draws bursts at higher currents.

Typical applications and use cases

The CR14250SE 3V is well-suited for power needs where space is at a premium and long life is valuable. Here are common application areas where this battery type shines:

• Memory backup and real-time clock (RTC) circuits in embedded systems and computers

• Security devices, access controls, and alarm panels that rely on stable standby power
• Utility meters and sensor networks where the device sits in a fixed location and replacement cycles are planned
• Watches, calculators, portable instruments, and other compact consumer electronics designed for long shelf life

From a stylistic standpoint, this section reads like a practical buyer’s guide. If your project involves a compact device that must not be recharged in the field, the CR14250SE 3V is a compelling option to evaluate against other CR-series cells or competing cylindrical Li primary cells. When writing product copy or a vendor page, you can emphasize how the form factor aligns with device tolerances, how the 3V nominal voltage helps maintain accuracy in clock circuits, and how the long shelf life minimizes stockouts in distributions channels.
