Atomfair 316 Stainless Steel Button Battery Holder (with O-Ring) and Matching Accessory Series Technical Parameter Description

1. Core Product Specification Parameters

The core products of this series are button battery holders of CR2016/2025/2032 models, which are processed with high-purity metal substrates such as 316 stainless steel (316ss) and 304 stainless steel (304ss). The chemical composition and mechanical properties of the substrates comply with ASTM standard specifications. Some models offer optional Au-plated and Al-coated surface treatment processes, achieving a surface roughness of Ra=0.8um through precision CNC machining, without processing burrs and micro-defects, which can effectively reduce contact resistance and improve corrosion resistance.

Product dimensions strictly match the specifications of corresponding battery models: CR2016 model is suitable for 20*1.6mm (diameter * thickness), CR2032 model is suitable for 20*3.2mm (diameter * thickness), and the dimensional tolerance of other models is controlled within ±0.05mm to ensure precise fit with the battery shell. The packaging specification adopts vacuum-sealed packaging of 100 pieces per bag (100pcs per bag), which can effectively isolate moisture and dust pollution and meet the clean storage requirements in laboratory environments.

The supporting accessory system is complete, covering key components such as button battery sealing gaskets and wave springs. Among them, the sealing gaskets provide multiple material options such as nitrile rubber (NBR), fluororubber (FKM), and silicone rubber (VMQ), adapting to different temperature (-40?~200?) and chemical environment requirements; the wave springs are made of 301 stainless steel with stable elastic coefficient, which can ensure reliable contact between the battery and the electrode. The full range of accessories provides multiple specification options to meet the customized assembly needs in different scientific research scenarios.

2. Core Product Performance and Scientific Research Application Scenarios

This product is specially designed for the packaging and protection of button batteries in scientific research scenarios. Its core advantage lies in the integrated O-ring sealing structure, which achieves IP67 protection level through precise compression control (recommended compression rate 15%~20%), effectively preventing electrolyte leakage and external environmental medium intrusion, and ensuring the long-term stability of the battery system.

In scientific research applications, this series of products can be widely adapted to the following scenarios:

• Reliability testing of electronic devices: providing stable power supply interfaces for prototype devices such as micro-sensors and low-power chips, and its low contact resistance (=50mO) characteristic can reduce energy loss in the power supply circuit and improve the accuracy of test data;
• Intelligent hardware prototype development: adapting to the battery module design of Internet of Things (IoT) nodes and wearable device prototypes, compatible with quick disassembly and assembly structures, facilitating researchers to carry out parameter debugging and module replacement;
• Industrial control and environmental monitoring: in harsh environment simulation experiments such as high and low temperature, humidity cycle, it can ensure the fixation, conduction and protection functions of battery components, meeting the requirements of environmental reliability test standards such as ASTM D1598.

The product has significant cost-performance advantages, balancing precision and economy: the standardized structural design can adapt to automated assembly processes, reducing the prototype production cycle; the modular component design facilitates the replacement and maintenance of individual parts, reducing the loss cost of scientific research samples, and fully meeting the use requirements of small-batch trial production and pilot test stages in laboratories.
