Long-Term Power for an Outdoor IoT Bike Locker
A customer in the United States was developing an outdoor electronic Bluetooth bike locker system and needed a primary lithium battery solution for the electronic locking and communication system.
Because the equipment would operate outdoors, the customer needed a battery configuration suitable for long-term operation while also fitting the electrical and mechanical requirements of the device.
After evaluating the application requirements, the customer selected the PKCELL ER341245 3.6V 35Ah Li-SOCl2 battery with a customized wire and connector.
Verifying the Battery in the Customer's Actual Device
Before moving directly into mass production, the customer requested samples for device testing.
PKCELL prepared the ER341245 samples according to the customer's connection requirements, including the required wire and connector. This allowed the batteries to be installed directly into the bike locker system during evaluation.
What the Customer Evaluated
After completing the sample test, the customer confirmed that the battery performance met the project requirements and moved forward with the first production order.
Wire and Connector Prepared for Direct Integration
For this project, the connection configuration was an important part of the battery solution.
Instead of supplying only a standard battery, PKCELL assembled the required wire and connector according to the customer's device requirements.
This configuration allowed the customer to integrate the battery into the device more efficiently without additional connection assembly work.
From Approved Sample to 1,000-Piece Production Order
Following successful sample evaluation, the customer placed an initial production order for 1,000 ER341245 batteries.
Before mass production, PKCELL reconfirmed the connection configuration and basic battery specifications against the approved sample.
The order was then produced and delivered according to the confirmed project requirements.
From Sample Testing to Annual Repeat Orders
Customer Inquiry
Application and battery requirements were discussed.
Sample Preparation
ER341245 samples were prepared with the required wire and connector.
Device Testing
The customer evaluated compatibility, voltage performance and operating stability.
Sample Approval
Testing confirmed that the battery solution met the customer's requirements.
1,000-Piece Mass Order
The first production order was placed based on the approved configuration.
Annual Repeat Orders
The project developed into stable long-term cooperation with repeat orders placed each year.
Why ER341245 Was Suitable for the Application
| Battery Characteristic | Application Benefit |
|---|---|
| 35Ah Capacity | Supports long operating periods and helps reduce battery replacement frequency. |
| 3.6V Nominal Voltage | Suitable for low-power IoT and electronic control applications. |
| Low Self-Discharge | Beneficial for equipment designed to operate for extended periods without frequent maintenance. |
| Wide Temperature Adaptability | Supports use in outdoor equipment exposed to changing environmental temperatures. |
| Custom Wire & Connector | Allows the battery connection to be prepared according to the customer's device requirements for easier installation. |
From Initial Validation to Stable Yearly Repeat Orders
After the first bulk order was put into use, the customer continued ordering the same ER341245 battery configuration.
Because the original battery and connection configuration had already been tested in the customer's Bluetooth bike locker system, subsequent orders could continue with a stable specification.
The project has since developed into long-term cooperation, with repeat orders placed on a yearly basis.
