Got a Button Cell in Your Device? GB 4943.1 Has Rules You Might Have Missed

If you make chargers, remote controls, wireless mice or small speakers — and your product has a button cell (the flat round battery in watches and car keys) — GB 4943.1-2022 has a few rules you may have missed.

First, what the standard is: GB 4943.1-2022 is China's mandatory national standard for the safety of audio/video, IT and communication equipment (the Chinese adoption of IEC 62368-1). Published 2022, in force since August 2023, it covers most mains-powered electronics sold in China today.

Why button cells get singled out

Because kids swallow them. A button cell looks like candy, and within two hours of being swallowed it can cause severe internal burns — sometimes fatal. Regulators have been tightening this globally: the US has Reese's Law, and China added dedicated battery clauses (section 4.8) in GB 4943.1-2022.

Two things it actually requires

1. The battery compartment must be child-resistant

For devices with button cells, the compartment can't be something a child just pops open. GB 4943.1 requires one of two options:

• Requires a tool: a screwdriver or coin, needing at least 0.5 N·m of torque and 90 degrees of rotation; or
• Two independent simultaneous actions: e.g., two clips pressed at once — one action alone won't open it.

In short: a child shouldn't be able to pry the cell out bare-handed.

2. Warning labels are not optional

Devices with button cells must provide the indicative safety protection per F.5 — basically, printed warnings in the right places. Core elements:

• "Do not swallow the battery; chemical burn hazard" or similar;
• "This product contains a button cell. If swallowed, it can cause severe internal burns within 2 hours and possibly death";
• "Keep new and used batteries away from children";
• "If the battery compartment does not close securely, stop using the product and keep it away from children";
• "If you suspect the battery has been swallowed, seek medical attention immediately."

These are mandatory elements, not suggestions — miss one and it gets flagged.

Good news: non-replaceable batteries relax this

The standard says if the battery is intended not to be replaceable (e.g., only accessible by destroying the device), the mandatory warning requirements are relaxed. Some products are designed with the cell permanently installed partly to avoid this overhead — but that's a design tradeoff, don't sacrifice usability just to dodge labeling.

How it relates to exporting to the US

If you sell on Amazon you've probably hit the UL 4200A compliance request — that's the US Reese's Law regime. The intent is identical on both sides: keep kids from swallowing button cells.

• Selling in the US: UL 4200A + Reese's Law requirements
• Selling in China: GB 4943.1-2022 clause 4.8 + F.5 labeling

Similar approach, different standard text — don't expect one report to cover both markets. Multi-market exporters typically prepare separate test reports or declarations.
