Button battery lawsuits are product liability claims filed on behalf of children who were seriously injured or killed after swallowing a coin-sized battery from a household product. The defendants are usually the maker of the product that contained the battery, the battery manufacturer, and increasingly the online marketplace that sold the item. The claims turn on how the battery compartment was designed, what warnings were given, and whether the product complied with federal safety requirements under Reese’s Law.
Why These Cases Carry Such High Damages
The injuries from a swallowed button battery are catastrophic and well documented. A 20mm lithium coin cell lodged in a child’s esophagus generates an electrical current that produces chemical burns through liquefactive necrosis. Severe tissue damage can begin within two hours, and esophageal perforation can occur within six.1National Library of Medicine. Button Battery Ingestion Injuries2Medscape. Button Battery Ingestion Treatment
Children who survive often live with permanent esophageal narrowing or a tracheoesophageal fistula, where the battery burns a hole between the airway and the food pipe. In the worst cases, the burn reaches a major blood vessel and the child bleeds to death.1National Library of Medicine. Button Battery Ingestion Injuries Early symptoms — coughing, irritability, trouble swallowing — look like a cold or croup, so diagnosis is often delayed.
A child under 18 arrives at a U.S. emergency department for a battery-related injury roughly every 75 minutes, and 84% of those patients are five or younger.3Nationwide Children’s Hospital.

Who Can Be Sued and On What Theory
Button battery claims use standard product liability law, which allows an injured consumer to recover from parties throughout a product’s chain of manufacture and distribution.5Cornell Law School. Products Liability Three theories do most of the work:
- Design defect: the battery compartment was built so a child could open it, or the battery itself had no safety features to reduce harm if swallowed.
- Failure to warn: the maker did not adequately warn consumers that ingestion is life-threatening or tell them to keep batteries away from children.
- Manufacturing defect: one particular unit was assembled wrong, letting the battery fall out during normal use.
Depending on the state, these claims proceed under strict liability, negligence, or breach of warranty. Strict liability is the dominant framework. A plaintiff does not need to show the defendant was careless, only that the product was defective and the defect caused the injury.5Cornell Law School. Products Liability
Can Amazon Be Held Liable?
Many of the products involved in these injuries are sold by third-party vendors on Amazon, often overseas sellers who are difficult to identify or serve. That makes the platform’s own liability a central question.
Amazon’s position is that it is not a “seller” because it never takes legal title to third-party goods, and its vendor agreements say so explicitly. Some courts have agreed. The Fourth Circuit held in Erie Insurance Co. v. Amazon.com, Inc. (2019) that Amazon was not a seller, and a federal court in New York reached the same result in Eberhart v. Amazon.com, Inc. (S.D.N.Y. 2018).6Cornell Law Review. Amazon’s Liability for Third-Party Products
Other courts have gone the other way. A Third Circuit panel ruled in Oberdorf v. Amazon.com, Inc. that Amazon qualifies as a seller under Pennsylvania law, pointing to its control over pricing, customer service, and listings, its ability to withhold payments from sellers, and the practical reality that Amazon is often the only locatable defendant.7Justia. Oberdorf v. Amazon.com Inc. The Third Circuit then granted en banc rehearing, vacated the panel opinion, and certified the question to the Pennsylvania Supreme Court. The parties settled in September 2020 before that court ruled, so no binding precedent emerged.8Villanova Law Review. Oberdorf v. Amazon Settles A CPSC administrative law judge separately concluded in 2022 that Amazon meets the statutory definition of “distributor” under the Consumer Product Safety Act.6Cornell Law Review. Amazon’s Liability for Third-Party Products
The practical result for anyone considering a claim: whether Amazon can be sued as a seller depends on the state whose law governs the case.
A Recent Settlement: Allen v. Amazon
The highest-profile recent button battery case is Allen et al. v. Amazon.com Services LLC, filed in the U.S. District Court for the Western District of Washington. A 16-month-old child suffered severe chemical burns to his esophagus after swallowing a button battery from a “Podfofo”-brand car stereo remote purchased on Amazon.9Law360. Amazon Settles Suit Over Child’s Button Battery Burn Injuries
On August 15, 2025, U.S. District Judge Lauren King approved the settlement as “fair and reasonable.” Court filings show Amazon and its insurers agreed to pay at least $517,000 in litigation costs and a $480,189 Medicaid lien. The total settlement amount was sealed.10CCH. Allen v. Amazon.com, Case No. 2:24-cv-00195-LK The case did not produce a published ruling on Amazon’s seller status, but the resolution shows the platform is willing to pay substantial sums to end these claims.
How Reese’s Law Shapes the Litigation
Reese’s Law (P.L. 117-171), signed August 16, 2022, is the federal statute that now governs button battery safety. It requires child-resistant packaging for button and coin batteries, mandates that battery compartments in consumer products be secured so they cannot be opened without a tool or two independent simultaneous hand movements, and imposes specific warning labels on products and battery packaging.11Federal Register. Safety Standard for Button Cell or Coin Batteries12U.S. Consumer Product Safety Commission. Button Cell and Coin Battery Business Guidance
For litigation purposes, the law creates a clear compliance baseline. A product that violates Reese’s Law is, by federal definition, inadequately designed or inadequately labeled. That evidence feeds directly into design defect and failure-to-warn claims, and it is often documented in a CPSC recall notice or notice of violation long before a case goes to trial.
Recalls That Can Support a Claim
Several 2025 and 2026 recalls illustrate what noncompliance looks like in practice:
- SIG SAUER recalled roughly 230,000 ROMEO5 red dot firearm sights in January 2025 because the included button cell batteries were not in child-resistant packaging, the products lacked required warnings, and the batteries could be easily accessed.13U.S. Consumer Product Safety Commission. SIG SAUER ROMEO5 Recall
- Pella recalled about 340 Reserve and Lifestyle sliding patio doors and remote controls in February 2025 because the sensor housings and battery compartments allowed easy access and lacked warnings.14U.S. Consumer Product Safety Commission. Pella Patio Doors Recall
- EEMB USA recalled roughly 312,100 lithium coin batteries in May 2026 because the pouches they were sold in were not child-resistant, in violation of Reese’s Law. The batteries had been sold on Amazon from August 2023 through April 2026.15U.S. Consumer Product Safety Commission. EEMB USA Battery Pouch Recall
- In January 2025 the CPSC issued a Notice of Violation to Apple because AirTags imported after Reese’s Law’s March 19, 2024 effective date lacked required warnings. The compartment itself met the physical security requirement. Apple agreed to add a warning symbol inside the battery compartment, update packaging, and revise the Find My app’s battery-change instructions.16U.S. Consumer Product Safety Commission. CPSC Agreement with Apple
If a child was injured by a product that was later recalled, or by one that CPSC has cited for a Reese’s Law violation, those documents are powerful proof that the manufacturer knew or should have known of the defect.
What Safer Battery Technology Could Mean
In May 2026 Energizer launched its “Ultimate Child Shield” line of 20mm coin lithium batteries in sizes CR2032, CR2025, and CR2016. The batteries use a titanium alloy instead of stainless steel to reduce digestive tract burns if swallowed, carry a nontoxic food dye that turns blue on contact with saliva, and have a bitter coating meant to deter swallowing.17Good Morning America. New Battery Aims to Prevent Child Deaths
The availability of safer batteries cuts both ways in future lawsuits. It may reduce the severity of some injuries, and with it the damages. It also raises the bar for competitors: once a safer design is commercially available, a plaintiff can argue that any manufacturer still using the older design has chosen a defective one.
