New Product Launch: LDA3048—A Long-Lasting Power Source for IoT Devices
June 16, 2026 Edited by Becky Wu
With the rapid proliferation of IoT technology, various types of end devices are evolving toward miniaturization, wireless connectivity, high-frequency communication, and remote deployment. From smart water meters to environmental monitoring sensors, and from wireless cameras to industrial automation controllers, these devices are placing increasingly higher demands on power supply systems. However, traditional coin-cell batteries often struggle to meet the instantaneous high-current demands of wireless modules such as NB-IoT and LoRa—voltage drops, communication interruptions, data packet loss, and even frequent device resets have become long-standing pain points in the industry.
To address this issue, we are pleased to introduce the LDA3048—a high-current, pulse-type rechargeable lithium coin cell battery designed specifically for IoT devices. Combining high energy density, extremely low internal resistance, and an exceptionally long cycle life, it is designed to serve as the most reliable and cost-effective power source for IoT end devices.
It can be said that the LDA3048 is not just a battery, but a long-lasting, maintenance-free, all-in-one power solution tailored for IoT devices such as NB-IoT and LoRa.
The specific specifications are listed in the table below:
Three Key Advantages:
I. High-Current Pulses for Stable, Worry-Free Communication
During normal operation, most IoT devices remain in sleep or low-power modes, with current surges occurring only momentarily when data is transmitted. Traditional button batteries, due to their high internal resistance, cannot deliver sufficient current in a short period, causing the voltage to drop rapidly. Once the voltage falls below the device’s operating threshold, it triggers a reset or data packet loss.
The LDA3048 completely transforms this situation. With a peak pulse output capability exceeding 2A, it effortlessly powers both RF modules and MCUs simultaneously, ensuring no voltage drop or system reset during transmission. Additionally, its ultra-stable voltage platform guarantees a smooth voltage curve during high-current discharge, providing continuous and stable power for data transmission. The ultra-low internal resistance design also minimizes energy loss, significantly improving power supply efficiency.
The end result is zero packet loss in communication links and rock-solid device operation. This breakthrough solves the industry-wide challenge of unstable traditional battery power and provides a solid foundation for IoT applications requiring high reliability.
II. Ultra-High Capacity: One Battery Equals a Thousand Button Cells
In terms of capacity, the LDA3048 also offers a revolutionary advantage. Traditional CR2032 button cells typically have a capacity of only around 25mAh, making them suitable only for simple, low-power devices with short operating cycles. In contrast, the LDA3048 boasts an energy density more than 12 times that of traditional button cells, and its single-cell capacity of 310mAh is sufficient to meet the long-term power demands of high-power devices.
More importantly, the LDA3048 supports over 500 charge-discharge cycles. While disposable button batteries are discarded once depleted, the LDA3048 can be reused repeatedly, with its total lifetime value equivalent to approximately 1,000 disposable button batteries. From a cost perspective, although the initial purchase cost is higher than that of disposable batteries, the LDA3048 offers exceptional value for money when replacement frequency and labor maintenance costs are taken into account.
Install once, enjoy long-term benefits. Whether for smart meters, wireless sensors, or security devices, the LDA3048 significantly reduces battery replacement frequency and overall maintenance costs.
III. Ultra-Long Lifespan, Ten Years of Maintenance-Free Operation
The LDA3048 not only excels in terms of single-charge capacity and cycle life but also features industrial-grade wide-temperature operation. With an operating temperature range spanning -20°C to +60°C, the LDA3048 delivers stable output with virtually no impact on performance, whether in the harsh outdoor environments of northern regions or the humid and sweltering industrial server rooms of the south.
In terms of safety, the LDA3048 has passed UN38.3 air transport safety certification and RoHS environmental compliance certification. It features built-in circuit protection against overcharging, over-discharging, short circuits, and other hazards, ensuring safety from the design stage. Users need not worry about safety risks during battery transportation or use.
Overall, the LDA3048 reduces operational and maintenance costs with its ultra-long lifespan, adapts to diverse scenarios with its wide-temperature performance, and establishes a solid safety foundation through authoritative certifications, making it a truly reliable power solution for industrial-grade IoT applications.
The LDA3048 is designed with the practical needs of various IoT devices in mind, and it delivers maximum value in the following typical scenarios:
Smart Meters: In fixed-installation devices such as smart water meters, gas meters, and electricity meters, battery replacement often requires disassembling the meter or entering the user’s premises, resulting in extremely high costs. The LDA3048’s ultra-long battery life and cycle life of over 500 cycles ensure that the device does not require battery replacement throughout its entire lifecycle, significantly reducing the maintenance burden on operators.
Wireless Sensors: Wireless sensor nodes in fields such as environmental monitoring, asset tracking, and smart agriculture typically require frequent or ad-hoc data reporting. The LDA3048’s high-current pulse capability ensures the timeliness and accuracy of every data transmission, preventing data loss caused by insufficient power supply.
Smart Security: Security devices such as smart door locks, wireless cameras, and smoke detectors demand extremely high reliability. The LDA3048’s high stability and exceptionally long service life effectively reduce safety risks caused by equipment failure or power outages, safeguarding homes and property.
Industrial IoT: In equipment condition monitoring and automation control systems, batteries often need to operate for extended periods in harsh environments such as high temperatures, humidity, and vibration. The LDA3048’s wide temperature range and stable output characteristics ensure the continuity and efficiency of industrial production processes.
In summary, the LDA3048 is more than just a battery; it is the cornerstone of reliable power for IoT devices. With its powerful pulse output capability, it instantly wakes up devices and handles complex operating conditions with ease; its high-energy-density cells significantly extend device replacement cycles and reduce downtime; its fully maintenance-free sealed design is dustproof and moisture-resistant, requiring no manual intervention; it optimizes cost-effectiveness from a full lifecycle perspective, significantly lowering the total cost of ownership; and it adheres to green and eco-friendly principles, using environmentally friendly materials and processes that are non-toxic, harmless, and easy to recycle.
If you are seeking a battery solution for IoT end devices that delivers high-current pulses, offers an ultra-long cycle life, and balances cost-effectiveness with safety, the LDA3048 is your ideal choice.
