A&S Power Expands UL 1642 Certified LiPo Battery Cell Portfolio

Introduction

When I discuss lithium polymer battery sourcing with OEM customers, I find that certification is rarely just a checkbox. For many engineering teams, purchasing departments and compliance managers, the certification status of a battery cell can affect supplier qualification, documentation, product development and market-entry planning.

That is why we are highlighting this latest UL 1642 certification update from A&S Power. The certificate covers rechargeable battery cells manufactured by Shenzhen A&S Power Technology Co., Ltd. and includes a broad range of models.

Among these models are 14 additional 3.7V lithium polymer battery cells that I want to highlight because they provide different dimensional and capacity options for compact rechargeable electronic products.

The newly highlighted models range from the compact 301525 3.7V 100mAh cell to the 755060 3.7V 3000mAh cell. This gives product developers more options when balancing battery size, capacity, runtime and available installation space.

UL 1642 Certification Details

The certificate identifies the product category as Rechargeable Battery Cells and references UL 1642, Edition 6. The certificate number, report reference and issue date provide clear identification information for customers reviewing the certification documentation.

14 Newly Highlighted UL 1642 LiPo Battery Cell Models

The following 14 models are the newly highlighted rechargeable lithium polymer battery cells covered by the certification information shown in this update. All models listed below have a nominal voltage of 3.7V.

What Does UL 1642 Mean for Lithium Battery Cells?

UL 1642 is a lithium battery safety standard focused on battery cells. For OEM battery projects, it is important to distinguish cell-level certification from certification of a complete battery pack or finished electronic product.

In practical OEM projects, I normally treat cell certification as one part of the overall battery compliance process. A certified cell does not automatically mean that every finished battery pack, BMS configuration, enclosure or end product has the same certification status.

This distinction matters when an OEM customer is selecting a cell for a new battery design. The final battery configuration should be evaluated according to its construction, application, electrical characteristics and target market requirements.

Why UL 1642 Documentation Matters for OEM Battery Development

1. Supplier Qualification

When I work with OEM customers, certification documentation is often reviewed during supplier qualification. A clearly documented certificate number, report reference and covered model list can make the technical review more straightforward.

2. More Cell Options for Different Designs

The 14 models highlighted here cover a capacity range from 100mAh to 3000mAh. This gives engineers more options when the available installation space, runtime requirement or device architecture changes.

3. Support for Global Battery Projects

International battery projects frequently involve multiple technical and regulatory requirements. UL 1642 documentation can therefore become one component of a broader compliance package, alongside transportation testing and other applicable standards.

4. A Starting Point for Custom Battery Development

I do not recommend choosing a battery based on capacity alone. For a custom battery project, I first look at available space, voltage, required runtime, current demand, connector, protection circuit and certification targets.

From 100mAh to 3000mAh: A Flexible 3.7V Cell Range

One useful feature of this portfolio is its wide capacity range. Smaller cells such as the 301525 at 100mAh and the 601225 and 501520 at 150mAh provide starting points for space-constrained electronics.

Mid-range models such as the 502540 at 500mAh, 102030 at 600mAh, 553035 at 600mAh and 582751 at 800mAh provide additional choices for portable electronics and IoT equipment.

At the higher end, the 903048 offers 1500mAh while the 755060 provides 3000mAh. These higher-capacity cells can be considered when longer operating time is required and sufficient internal volume is available.

Actual suitability depends on more than capacity. The final cell selection should also consider dimensions, discharge requirements, operating temperature, charging conditions, protection requirements and the mechanical design of the host device.

Potential Applications for These 3.7V LiPo Battery Cells

Because the models cover different dimensions and capacities, they can be considered for a broad range of compact rechargeable products. Depending on the final electrical and mechanical requirements, typical application directions may include:

• Wearable electronics
• GPS trackers and portable IoT devices
• Handheld consumer electronics
• Smart beauty and personal-care equipment
• Portable medical and healthcare equipment
• Industrial handheld devices
• Portable monitoring equipment
• Other compact rechargeable electronic products

These applications are examples rather than a statement that every listed model is suitable for every application. The correct cell should be selected according to the actual device specifications and certification requirements.
