Introduction: Why Battery Selection Shapes IoT Success
Long-Term Deployment Needs
Bluetooth beacons and low-power IoT devices are built for long-term deployment. They are installed in places where changing or recharging a battery every few months is not an option. In such cases, the battery is more than just a power source. It is the foundation of reliability, scalability, and cost-effectiveness.
Why ER14505 is Trusted
Among the batteries, the ER14505 lithium thionyl chloride (Li-SOCl₂) is one of the most trusted solutions for these demanding applications. With its high energy density, wide temperature tolerance, and exceptionally low self-discharge rate, the ER14505 has become the go-to choice for engineers and system integrators designing solutions that must operate unattended for years.
Understanding the ER14505: A Technical Overview
Core Specifications
The ER14505 is a primary 3.6V AA-size cell. It is designed specifically for low-drain, long-duration applications. Its chemistry gives it a number of advantages over traditional alkaline or rechargeable options, particularly when stability and longevity are critical.

Key Advantages
At its core, the ER14505 offers high energy density, which means it packs a significant amount of energy into a compact AA form factor. This allows IoT devices to run for years without replacement, even in remote or hard-to-reach locations. Its extremely low self-discharge rate—typically less than 1% per year— ensures that the stored energy remains available throughout its shelf life, which can extend to a decade or more.
Operating Conditions
Another defining feature is its wide operating temperature range, from -60°C to +85°C. This makes it reliable in harsh outdoor conditions, cold chain logistics, or industrial environments where fluctuations are common. Unlike rechargeable lithium-ion cells, which degrade significantly in such conditions, Li-SOCl₂ batteries maintain predictable discharge behavior across the range. Finally, the ER14505 delivers a stable voltage output of 3.6V, ensuring that connected devices like Bluetooth beacons or wireless sensors operate consistently over time.
Why Bluetooth Beacons Depend on Long-Life Batteries
Continuous Operation
Bluetooth beacons have become central to asset tracking, indoor positioning, and smart retail applications. Their function is simple: transmit small packets of data at regular intervals to nearby receivers, often for years at a time. But behind that simplicity lies a demanding power requirement. Beacons must work continuously without user intervention.
Performance in Challenging Environments
The ER14505 addresses this challenge by combining long operational life with predictable performance. For example, a beacon configured to broadcast every few seconds can run for five to ten years on a single ER14505 cell, depending on transmission power and environmental conditions. Furthermore, Bluetooth beacons are often used in dynamic environments such as airports, shopping malls, or manufacturing plants. Thanks to its wide temperature tolerance and reliable discharge profile, the ER14505 ensures that beacon networks continue to function without degradation, even in the most challenging scenarios.

ER14505 in Low-Power IoT Devices: Reliability at Scale
Meeting IoT Device Demands
IoT devices are expected to blend into the background and perform silently for years. The defining trait of these devices is low power consumption, yet even a few microamps of current, when multiplied over years, can exhaust weaker batteries. The ER14505 meets this need with its high capacity, typically around 2.6Ah in standard cells, and with extended versions available that push this figure higher.
Business Impact
Its low self-discharge ensures that the majority of stored energy goes into powering the device, not being wasted in storage. This makes it possible to design sensors and transmitters that can remain active and reliable for five, seven, or even ten years without battery intervention. For system integrators deploying thousands of sensors in industrial or municipal projects, this long life translates directly to lower total cost, less labor, fewer disruptions, and reduced waste.
Real-World Applications: From Logistics to Smart Cities
Logistics & Supply Chain
In logistics and supply chain tracking, these batteries power asset tags that monitor shipments over years, ensuring that goods remain traceable without ever needing a battery swap.
Industrial IoT
In industrial IoT, ER14505 cells keep wireless sensor networks alive in factories, reporting on machine health and environmental conditions.
Smart Citie Devices
In smart city deployments, they are used in sensors that track air quality, traffic, or waste bin levels, enabling municipalities to run data-driven infrastructure without the burden of constant maintenance.
Choosing the Right ER14505 Supplier
