Button cell battery safety checks for imports
Check whether button or coin cells can be avoided, whether children could access them, whether the compartment stays securely closed, and whether warnings reach buyers before purchase. Match testing to the finished product and inspect production samples. Cambridge China Bridge can coordinate these checks with its staff in China.
Start with foreseeable child access
OPSS recommends considering alternative power sources before using button or coin cells. Its guidance sets out best practice and introduces no new requirements. This guide covers finished-product containment and ingestion risks; our battery sourcing guide covers the cells themselves.
Map where children could encounter the product, including a remote control supplied with adult equipment. Consider handling, dropping, battery replacement and a cover refitted incorrectly. Ask whether a child could reach a cell through the cover or damaged casing. An adult-use label should not end your assessment.
Specify secure containment before sampling
OPSS advises that the battery compartment should fasten securely and not open inadvertently, preventing children from removing the batteries. Put the closure design, fastener, casing material and replacement procedure in your product specification.
Examine the actual sample: does the screw engage properly, does the cover seat fully, and can the casing flex enough to release a cell? Repeat opening and closing to look for stripped threads or weakened clips. Treat these as purchasing checks, with formal test methods and acceptance criteria agreed with a competent laboratory.
Ask for finished-product test evidence
OPSS encourages following its recommended battery-safety specification, while following product-specific standards where they contain more detailed requirements, such as for toys or audiovisual equipment. Ask the laboratory to identify the applicable standards and editions for your product and destination before approving its test plan.
A cell report does not establish that the finished compartment contains the battery securely. Match the report to the housing, cover, fastener and cell fitted in your sample. Request photographs and results covering access and containment after the applicable tests. Use our test-report verification guide to check the evidence.
Approve warnings across the buying journey
OPSS advises prominent, clear warnings on the product, packaging and supplied instructions or manual. For distributors, it also recommends warnings at shop points of sale and in online descriptions or images, alerting consumers before purchase.
Agree wording that clearly explains the ingestion hazard, keeping batteries away from children and what to do if ingestion is suspected. Check readability on printed samples and the actual sales listing. Include safe replacement, secure storage of removed cells and disposal instructions. Treat warnings as additional protection alongside secure containment.

Check production and control changes
Add compartment checks to the inspection brief. Inspect production samples with the supplied batteries fitted, then open, replace and refasten them using the instructions. Check for missing screws, incomplete engagement, loose covers, cracked housings and differences from the tested sample.
Hold shipment if a cell becomes accessible or the closure differs from the approved design. Record the affected batch and require correction, followed by reassessment and appropriate retesting. Keep approved samples, photographs, artwork and reports together; require approval before changes to the cover, fastener, material or cell.
Frequently asked questions
Do adult electronics need button battery checks?
Include them in your assessment if children could encounter them. Examine remotes and accessories as well as the main device; the intended adult user does not settle whether a child can access a battery.
Is a screw enough to secure a battery compartment?
Check the complete closure. A screw can be missing, strip its thread or fail to hold a flexible cover. Agree applicable testing with a laboratory and check production matches the tested construction.
Can a battery warning replace a secure compartment?
OPSS recommends warnings in addition to secure containment. Address access through the cover and casing, then approve warnings on the product, packaging, instructions and sales materials.
Does a cell test report cover the whole device?
It does not establish finished-product containment. Request evidence for the actual housing, cover, fastener and fitted cell, and check that production matches the tested sample.
