Samsung Battery Swelling: What the Official Records Say

What a Swollen Battery Means If Your Device Is Bulging

Battery swelling means a lithium-ion cell has expanded beyond its normal shape. Inside a sealed device, that expansion can push against the case, the back panel or the screen. Swelling is a physical sign that something inside the cell has changed. It does not say on its own why it happened, or whether anyone is responsible.

Two other terms come up in almost every discussion of battery failures. Thermal runaway is a cycle in which heat inside a cell feeds more heat, faster than the cell can shed it, and it can end in fire. A battery management system is the circuitry that watches a battery's charging, discharging and temperature. When people ask why a battery failed, questions about the cell and about that monitoring circuit are often part of the answer.

For someone holding a swollen device, the stake is that the bulge alone settles nothing: it does not show whether a recall covers the product or whether its condition is a defect in the legal sense. Those answers come from the official record and the facts of a specific situation. People in this position often start by noting the device's make and model and whether it was ever opened or repaired, since those details shape every later question.

The general explanation of why lithium-ion cells swell, and what the warning signs look like, is on this site's Swollen Lithium Battery page. This page stays with a narrower question: what the official federal records say about Samsung products, and how the law treats a battery failure in any device.

Does a Samsung Recall Cover Your Device? What the CPSC Records Say

A recall is a corrective action for a product, announced with or ordered by a government agency. It can involve a repair, a replacement or a refund. A recall is not a court's finding that the product injured anyone, and it is not a finding that the company is liable.

The U.S. Consumer Product Safety Commission (CPSC) published the two notices below. Each names Samsung Electronics America Inc., of Ridgefield Park, N.J., as the manufacturer.

On September 15, 2016, the CPSC published recall 16-266, "Samsung Recalls Galaxy Note7 Smartphones Due to Serious Fire and Burn Hazards." The notice states the hazard this way: "The lithium-ion battery in the Galaxy Note7 smartphones can overheat and catch fire, posing a serious burn hazard to consumers." It covers "the Samsung Galaxy Note7 smartphone sold before September 15, 2016," about 1 million units. It lists refund and replacement as the remedies, including "a new Galaxy Note7 with a different battery." Under incidents, the notice reports that "Samsung has received 92 reports of the batteries overheating in the U.S., including 26 reports of burns and 55 reports of property damage, including fires in cars and a garage."

On October 13, 2016, the CPSC published recall 17-011, "Samsung Expands Recall of Galaxy Note7 Smartphones Based on Additional Incidents with Replacement Phones; Serious Fire and Burn Hazards." It states the hazard as a battery that "can overheat and catch fire, posing serious fire and burn hazard to consumers." It covers "all Samsung Galaxy Note7 smartphones," including replacement devices from the September recall, about 1.9 million units in total, a figure the notice says includes the earlier 1 million. Its remedies are refund and replacement. It reports that "Samsung has received 96 reports of batteries in Note7 phones overheating in the U.S., including 23 new reports since the September 15 recall announcement," along with "13 reports of burns and 47 reports of property damage associated with Note7 phones." The notice lists wireless carriers, electronics stores and websites as places the phones were sold.

So the federal record here is about overheating and fire in one phone model; swelling does not appear as the stated hazard. The notices say nothing about other Samsung devices, and they are not evidence of a pattern across the brand.

The incident counts are reports the company received, as each notice states them. A report is not proof of what caused any particular injury, and a lawsuit, if one exists, is not a finding of liability.

Federal law sets out what these notices are for. Under 15 U.S.C. § 2064, a manufacturer, distributor or retailer that obtains information which "reasonably supports the conclusion" that a product fails to comply with an applicable consumer product safety rule or a voluntary consumer product safety standard the Commission has relied on, fails to comply with any other rule, regulation, standard, or ban under the chapter or any other Act enforced by the Commission, contains a defect which could create a substantial product hazard, or "creates an unreasonable risk of serious injury or death," must immediately inform the Commission, unless it has actual knowledge that the Commission has already been adequately informed. The same section lists what a recall notice ordered by the Commission generally includes, among them the product's description, the hazard, the number of units, and "any remedy available to a consumer."

For a reader, the practical question is whether a device matches a notice's product description. Someone with a Note7 may compare the model and IMEI to the notice; someone with another Samsung device may note that these records do not reach it, and that the absence of a recall is not the end of the inquiry. Other brands' records follow the same pattern, as the site's pages on Anker battery fire recalls and the INIU power bank recall show.

Records and Information People in This Situation Usually Gather

If you were hurt when a device's battery swelled, overheated or caught fire, the records that usually matter fall into a few groups. Medical records document the injury and the treatment that followed. Photographs and video show the device, the swelling, and any scorching or damage to the room, the car or other property.

The device itself often matters most, along with its original box if it still exists. A battery that failed is physical evidence. Its model number, its condition and whether it was ever opened or repaired can shape what anyone can later say about why it failed. For the Note7, the September 2016 notice explained that its IMEI number appears "on the back of the phone or the packaging."

Purchase records help show what the product was and where it came from: a receipt, an order confirmation, a carrier account history or a gift card record. When a fire department or police officer responded, their incident report may record what they saw. The names and contact details of anyone who saw the device fail can matter too.

Families after a house fire or a death often face this list while also grieving or dealing with insurers and repairs. Not every item exists in every situation. A device that swelled and was set aside raises different questions from one that burned someone. A conversation with our attorney can help sort out which of these records bear on a particular situation.

If a Swollen Battery Hurt Someone, Who May Be Responsible

Product liability is the body of law that may hold the businesses that make or sell a product responsible when a defect in it causes injury. It looks at roles in the chain that brought the product to the person hurt: the manufacturer of the device, the maker of the battery cell, an importer, a distributor, a retailer, and sometimes a repair shop that replaced a battery.

A defect, in plain terms, is a flaw that makes a product less safe than it should be, and the kind of defect points to where the questions go. If the concern is a design defect, the question is whether the product's design itself carries an unreasonable risk, which looks at the model rather than one unit. If it is a manufacturing defect, the question is whether one unit, or one batch, came out different from the intended design, which is where the specific device kept after a failure can matter. If it is a warning defect, the question is whether the instructions or warnings adequately told people about a risk, so the box and manuals become relevant.

The CPSC's own regulation describes the idea in similar terms. Under 16 C.F.R. § 1115.4, "a defect is a fault, flaw, or irregularity that causes weakness, failure, or inadequacy in form or function." The regulation adds that "a product may contain a defect even if the product is manufactured exactly in accordance with its design and specifications, if the design presents a risk of injury to the public," and that a defect "can also occur in a product's contents, construction, finish, packaging, warnings, and/or instructions." That regulation guides companies deciding what to report to the Commission. State product liability law sets its own tests for an injury claim.

Swelling can come before a fire, and it does not always lead to one. A device that bulged and was set aside has not caused the same harm as one that burned a person. In either case, a claim generally turns on elements the law requires: a defect or a duty, its breach, causation (that the defect actually caused the harm) and damages. A recall does not by itself prove a defect in any one device, and the absence of a recall does not rule out a claim. What is at stake for an injured person, then, is less the brand name than the proof linking this device to this harm.

Some states apply strict liability, meaning a manufacturer or seller may be held responsible for a defective product without proof that it was careless. Whether that applies, and to which roles in the chain, depends on the state. Which parties may be responsible depends on who made the battery, who sold the device, whether it was modified or repaired, and the law of the state involved. People in this position often weigh who sold or repaired the device and what records show it, questions a conversation with our attorney can help sort out. Naming a brand on this page says nothing about responsibility in any case.

How State Law Shapes a Battery Swelling Claim

State law, not one national rule, governs most injury claims over a battery failure. The rules differ from state to state, and no state's version is the rule everywhere.

A statute of limitations is the deadline for filing a lawsuit; after it passes, a court may refuse to hear the claim. The period differs by state and by the type of claim. Each state's law also sets when the period starts to run. In many states that is tied to the date of injury, or to when the injury was or reasonably should have been discovered, and each state has its own exceptions. Some states also have a statute of repose, an outer limit tied to the product itself rather than the injury. If you are trying to understand a deadline, the answer comes from the specific statute of the state whose law applies.

Fault rules matter when questions arise about how the device was used or charged. Under comparative fault, a court weighs the injured person's own share of responsibility and may reduce recovery by that share, so a disputed charging habit might lower rather than end a claim. Under contributory fault, an older, stricter approach, the injured person's own fault can bar recovery. States follow different versions of these rules, and the differences can be large.

Damages are the categories of loss the law may allow a court to award. Depending on the state, these can include medical expenses, lost income, pain and suffering and property damage. For someone after a battery fire, this is why medical bills, records of missed work and photos of damaged property tend to matter; whether any category applies depends on the facts and the state's law.

Wrongful death is a claim surviving family members may bring when a person dies because of a defective product or another's wrongful conduct. Each state's wrongful death statute decides who may bring it, the deadline and what damages it allows. For one state's rules, the site's California lithium battery injury page sets them out as California's rules only.

For a family after a fire, or someone recovering from burns, the state question often shapes everything else. If you would like to talk through which state's deadline and rules may apply to what happened, you can request a case evaluation to discuss it with our attorney.
