CR14250 3V 800mAh Primary Lithium Manganese Dioxide Cylindrical LiMnO2 Battery

800mAh Capacity. Long-Term Standby Autonomy for Space-Constrained PCBs.

When hardware blueprints require more energy density than a flat coin cell can deliver, but physical space constraints eliminate standard AA housings, the CR14250 3V 800mAh Primary Lithium Manganese Battery serves as the optimal engineering solution.

Adopting the compact 1/2 AA size profile of 14.5 × 25.0mm e pesando apenas 9g, this non-rechargeable cell delivers a dense 800mAh energy reservoir. It provides high voltage stability and low internal resistance, tailored specifically to eliminate routine field maintenance for remote sensors, emergency equipment, and data backup arrays.

Vantagens principais de engenharia e utilidade B2B

1. Space-Optimized 1/2 AA Geometry

The CR14250 reduces layout overhead by exactly 50% compared to a standard AA cell, allowing engineers to reduce the enclosure sizes of handheld tools, smart meters, and tracking hardware without forcing a compromise on battery capacity.

2. High-Pulse Capacity via Spiral Design

Unlike bobbin-style cells that suffer from temporary voltage delay or passivation under heavy loading, our CR14250 utilizes a precision spiral-wound inner structure. This design increases the chemical reaction surface area, enabling the battery to cleanly support the instant micro-second current surges required by wireless transceivers and RF modules.

3. Decadal Storage Stability (≤2% Self-Discharge)

Featuring a high-purity lithium metal anode matched with hermetic glass-to-metal sealing technology, internal chemical aging is limited to under 2% annually. Your finished products can remain idle in inventory or run in ultra-low sleep modes for up to a decade and still perform instantly when activated.

4. Extrema Resistência Térmica (-40°C a +70°C)

The battery’s internal organic electrolyte retains stable ionic mobility under freezing outdoor field conditions (-40 °C) while resisting high-temperature pressure generation and rapid self-discharge inside unventilated industrial enclosures (+70 °C).

Perguntas Frequentes

Q1: Can a CR14250 battery replace a standard AA battery?

A: No. While they share the same diameter (14.5mm), the CR14250 is exactly half the length (25.0mm vs 50.5mm). Additionally, the CR14250 delivers a 3.0V output, whereas a standard consumer AA battery delivers 1,5 V. Using a 3V cell in a circuit designed for 1.5V will cause over-voltage damage to the microprocessors.

Q2: Is the CR14250 battery rechargeable?

A: No. The CR14250 is a bateria primária (de uso único) de dióxido de manganês-lítio. Ela não pode ser recarregada com segurança. Tentar forçar corrente nessa célula irá romper a vedação hermética interna, levando a vazamento de eletrólito, curtos internos ou fuga térmica.

Q3: Why is the ≤2% self-discharge rate crucial for memory backup and smart meters?

A: Industrial smart meters and memory backup circuits spend the vast majority of their lifecycles in ultra-low micro-amp sleep states, waking up for mere milliseconds to log or transmit data. A self-discharge rate of ≤2% ensures that the battery’s energy is preserved for actual device operations over a span of up to 10 years, rather than wasting away internally.
