Why Battery Certification Matters for OEM Projects

In a commercial battery sourcing project, the battery itself is only one part of the qualification process. OEM customers may need to review electrical specifications, mechanical drawings, protection-circuit information, safety documentation, transportation reports, and certification records before approving a battery for production.

From my experience working with customized lithium battery projects, certification documentation becomes particularly important when the battery is being integrated into a regulated or safety-sensitive product. Having the relevant documents available early can make engineering review and supplier qualification more efficient.

However, battery-level certification should not be interpreted as automatic certification of every finished product in which the battery may be used. The final product can have additional electrical, EMC, mechanical, environmental, transportation, or regulatory requirements.

Potential Applications for the AS552035 Battery

With its compact 3.7V 350mAh format, the AS552035 can be considered for various small electronic devices where a rechargeable lithium polymer battery is required.

IoT Devices Compact rechargeable power solutions for connected electronic products.
Portable Electronics Battery-powered devices where compact dimensions are important.
Communication Equipment Suitable for compact communication-related electronic equipment, subject to final product requirements.
Wearable and Smart Devices Small LiPo battery applications where packaging space is limited.

OEM and Custom LiPo Battery Options

The AS552035 is a standard battery model, but battery requirements are often different from one product to another. Depending on the project, A&S Power can support customization of battery dimensions, capacity, connector type, wire length, protection circuitry, and pack configuration.

For example, the AS552035 specification uses a compact pouch-cell format with a protection circuit option. The battery can also be configured to match the mechanical space and electrical interface of the customer's equipment.
