What defines the ER14505 and its core technical advantages?

The Lithium ER14505 battery is a high-energy density 3.6V Li-Socl₂ battery specifically engineered for long-term industrial use.

Featuring a bobbin-type construction, it offers a stable operating voltage, a wide temperature range from -60°C to +85°C, and an exceptionally low self-discharge rate of less than 1% per year. These characteristics make it the premier choice for utility metering and remote sensing applications.

Technical Specifications and Chemical Composition

The chemical backbone of the ER14505 is the Lithium Thionyl Chloride system. At Long Sing Technology, from a production perspective, we utilize high-purity electrolytes to ensure that the lithium ER14505 battery for OEM applications maintains a flat discharge profile.

This is crucial for electronic components that require a steady voltage throughout the battery’s life cycle. Based on long-term cell testing, our AA-sized cells consistently outperform generic alternatives in extreme environments.

When engaging in ER14505 procurement for industrial use, it is vital to understand that the “ER” prefix denotes the lithium-thionyl chloride chemistry, whereas an “LR” or “FR” prefix would indicate alkaline or lithium-iron disulfide.

hybrid supercapacitor. This combination allows for a high continuous energy supply while managing the peak currents required for IoT data transmission.

How does ER14505 vs ER14500 compare for high-reliability OEM applications?

The comparison between er14505 vs er14500 is often a matter of nomenclature, as both refer to the AA size 3.6V Li-Socl₂ battery.

However, in professional procurement, the “ER14505” label is frequently associated with high-capacity bobbin cells (2700mAh), while “14500” can sometimes refer to 3.7V rechargeable Li-ion cells.

For industrial OEMs, choosing the lithium ER14505 battery ensures a non-rechargeable, ultra-long-life power source optimized for low self-discharge and maximum safety.

Critical Comparison for Industrial Sourcing

In our experience as an lithium ER14505 battery supplier, customers often ask if they can substitute a standard consumer cell for industrial tasks. The answer lies in the pulse load and environmental stress.

Comparing er14505 vs er14500 requires a deep dive into the internal resistance and the thickness of the lithium anode. For a project involving ER18505 cells (A size) or AA sizes, the build quality determines whether the battery will last 2 years or 10 years.

The procurement of ER14505 vs ER14500 for heavy-duty metering involves verifying the glass-to-metal seal integrity.

At Long Sing Technology, we emphasize that low cost ER14505 battery sourcing should never come at the expense of sealing quality. Our ER18505 and ER14505 lines utilize laser-welding technology to prevent electrolyte leakage, which is common in cheaper alternatives.

When comparing er14505 vs er14500, always check the manufacturer’s testing data for high-temperature storage, as this reveals the true stability of the chemistry.

Why is Anti-Passivation Technology critical for long-term power reliability?

Anti-Passivation Technology is a specialized manufacturing process that prevents the buildup of a resistive lithium chloride layer on the anode of a Li-Socl₂ battery.

This technology ensures that the battery can provide an immediate voltage response even after years of inactivity or storage at high temperatures. For OEMs, this eliminates “voltage delay” issues that can cause microcontrollers to reset during high-current pulse events.

Case Study with a German Industrial Client

As a premium lithium primary battery manufacturer, we recently collaborated with a German engineering firm on a large-scale smart meter deployment.

They initially struggled with low cost litihium ER14505 battery sourcing from unverified vendors, leading to widespread passivation in the field.

Our team at Long Sing Technology initiated a comprehensive solution process: we started with rigorous sampling, followed by real-time simulation of their 10-year load profile.

When initial samples showed a slight voltage dip under cold-start conditions, we performed rapid R&D rework on the electrolyte formula to enhance ion mobility.

The client’s feedback was overwhelming; they noted that the lithium ER14505 battery procurement for industrial use was finally simplified by our transparent communication and technical depth.

By implementing advanced Anti-Passivation measures, we helped them avoid a multi-million dollar recall.

Whether you are using ER18505 for larger sensors or the standard ER14505 vs ER14500 debate, our Chinese facility ensures that every batch meets the stringent safety standards of Western Europe and North America.

For applications requiring even higher pulse currents, we can integrate a hybrid supercapacitor (HPC) with our cells, or suggest a Li-MnO₂ solution if the application favors high discharge over maximum shelf life.
