Breaking: Our Consumer Electronics Battery Series Receives UL 2271 Certification – Ready for the North American Market

1.What is UL 2271 Certification?

UL 2271 is a safety standard developed by Underwriters Laboratories (UL), specifically designed for batteries used in light electric vehicles (LEVs) and mobile devices.

  1)Scope of Application

UL 2271 applies to lithium-ion batteries used in:

Robot vacuum cleaners

Electric scooters

Electric balance boards / hoverboards

Electric bicycles

Electric wheelchairs

Other light mobility devices

  2)Key Requirements

UL 2271 evaluates battery safety across three dimensions:

Electrical safety: No fire, no explosion under abnormal conditions such as overcharge, over-discharge, or short circuit

Mechanical safety: No leakage, no fire, no explosion under physical stress such as crush, impact, vibration, or drop

Environmental safety: Stable performance under temperature cycling, high-temperature exposure, and low-pressure conditions

  3)Market Value

In North America, UL 2271 is a mandatory requirement for lithium-ion batteries. Without it, robot vacuum brands cannot sell through major retailers or gain consumer trust. This certification is the gateway to the North American market.

2.UL 2271 Test Items – All Passed with Excellence

The UL 2271 certification process involves a series of stringent tests. Our batteries passed every single test without exception. Below is an overview of the key tests and our results.

3.What Does UL 2271 Certification Mean for Our Customers?

UL 2271 is more than a certificate-it delivers real value to our customers.

No need for duplicate testing: Use our certified batteries and your entire product meets North American safety requirements

Faster time to market: Save 3–6 months of certification lead time

Lower compliance costs: Avoid tens of thousands of dollars in testing fees

For End Users

Peace of mind: UL certification is a trusted safety mark for North American consumers

Reliable performance: Batteries that pass rigorous testing last longer and have lower failure rates

For Importers and Distributors

Reduced supply chain risk: Certified batteries reduce the risk of product recalls caused by battery issues

Lower liability exposure: UL compliance provides strong defense in product liability cases

Choosing our batteries means choosing a globally compliant solution. Whether your target market is North America, Europe, Japan, or China, we have the certifications you need.

4.How We Ensure Consistency in Certified Products

Passing certification is just the first step. Maintaining consistency across mass production is equally important. Here's how we ensure every battery meets the same high standards:

Raw material control: All key components (cells, ICs, MOSFETs, connectors) come from top-tier brands and undergo 100% incoming inspection

Process control: Critical manufacturing processes (welding, assembly, testing) are monitored with real-time quality checkpoints

100% final testing: Every battery is tested before shipment, including:

Open circuit voltage

Internal resistance

Charge/discharge function

Communication function (for BMS-equipped models)

Visual inspection

Regular sampling: We randomly sample batteries from production each month for internal re-testing of key UL 2271 items to ensure ongoing compliance
