If a loose 18650 lithium-ion cell or a mechanical-mod vape exploded in your pocket or hand in Florida and burned you, you generally have four years to file a product-liability claim under section 95.11(3)(d), Florida Statutes. If the explosion killed someone, the wrongful-death deadline is two years under section 95.11(5)(e), Florida Statutes, and a general negligence claim against a seller runs two years under section 95.11(5)(a). These cells are built as industrial components of battery packs and are not meant to be sold loose to consumers. The U.S. Consumer Product Safety Commission warned on January 8, 2021, that loose 18650 cells can short on keys or coins in a pocket, enter thermal runaway, and expel burning contents. Florida follows strict products liability under West v. Caterpillar Tractor Co., 336 So. 2d 80 (Fla. 1976). Save the cell, the device, the wrapper, and the receipt, because the physical evidence is the case. Graham W. Syfert, Esq., is Of Counsel to the Soud Law Firm and handles these burn claims. Past results do not guarantee a similar outcome.
Here is the prayer for relief first. If a loose 18650 lithium-ion cell or a mechanical-mod vape exploded against your body in Florida and burned you, you likely have a product-liability claim. The deadline for a personal-injury products claim is four years under section 95.11(3)(d), Florida Statutes. If the explosion killed someone, the wrongful-death deadline is two years under section 95.11(5)(e), Florida Statutes. Do not wait to learn which clock applies to your facts.
The injured person is the one to root for. People who carry a spare cell in a pocket are not doing anything reckless. They are doing what the vape shop showed them. The cell shorts on a key or a coin, overheats, and vents a jet of flame into a pant leg in seconds. Third-degree burns to the thigh and groin follow, then skin grafts, then scars that do not fade.
The antagonist is the defective cell and the seller who handed it over loose with no warning. A bare 18650 cell has exposed metal terminals. It was built to live inside a sealed battery pack, not in a pocket next to your keys. Graham W. Syfert, Esq., is Of Counsel to the Soud Law Firm and brings these claims against the manufacturer and the seller. Past results do not guarantee a similar outcome.
A lithium-ion 18650 cell stores a large amount of energy in a small metal can. When the positive and negative terminals touch a piece of metal at the same time, the cell short-circuits. The short heats the cell from the inside. Once the internal temperature climbs past the failure point, the cell enters thermal runaway. The reaction feeds itself, the cell can no longer cool down, and it forcibly expels its burning internal materials.
The U.S. Fire Administration studied 195 separate e-cigarette explosion and fire incidents reported in U.S. media between January 2009 and December 31, 2016. Those incidents caused 133 acute injuries, and 38 of them, 29 percent, were severe. The agency wrote that the shape and construction of these devices make them more likely than other lithium-ion products to behave like flaming rockets when a battery fails.
The location of the injury is the cruel part. The Fire Administration found that the severe injuries happened while the device was in the victim's mouth, in close proximity to the face, or in a pocket. It wrote that no other consumer product typically used so close to the human body contains the lithium-ion battery that is the root cause of these incidents. That intimacy is what makes the burns so deep.
A vaper who runs two cells will carry a charged spare. The spare rides in the same pocket as keys and loose change. The bare wrap on a rewrapped cell tears, the terminals touch the metal, and the short begins. The U.S. Consumer Product Safety Commission described this exact path on January 8, 2021. It warned that loose 18650 cells can short when they contact metal objects such as keys or loose change in a pocket.
Once the short starts, there is no fuse and no protection circuit in a bare cell to stop it. The cell vents in seconds. The victim feels heat, then sees flame coming through the fabric, and the burning material keeps reacting even as he tries to bat it out. This is why the burns reach the third degree before the victim can act.
A mechanical mod, or mech mod, draws power straight from the cell with no circuit board between the battery and the coil. There is no voltage regulation, no short-circuit cutoff, and no overheat protection. If the user builds a coil with too low a resistance, or if the cell is stressed, the current can run away. The mod becomes a sealed metal tube around a venting cell, and it can launch its end cap like a projectile.
The risk is not theoretical. In St. Petersburg, Florida, a mechanical-mod explosion drove pieces of the device into a user's skull and killed him, a fact discussed in the brands and cases below. A mech mod places the entire burden of safety on the user and the cell, and when the cell is defective, the user pays.
The cells inside vapes carry famous names. LG Chem, Samsung SDI, Sony, and Murata all make 18650 lithium-ion cells. The crucial fact is that none of these makers sells these cells to the public as standalone vape batteries. They build them as industrial components to be welded inside sealed battery packs for power tools and laptops. Samsung SDI has stated that its replaceable lithium-ion cells are not manufactured for individual consumer use and are not designed or produced for use in any vape or e-cigarette.
The cell in your pocket usually traveled a gray path to get there. The Consumer Product Safety Commission explained on January 8, 2021, that these cells are separated from packs, rewrapped, and sold as new consumer batteries, typically over the internet. The rewrap hides the original maker's marking and the warning. Sony and Murata VTC cells, for example, carry a warning on the metal can that they are not to be used outside of a battery pack.
Brand identity drives the legal theory. If a genuine LG, Samsung SDI, or Sony cell failed because of a manufacturing or design defect, the cell maker may answer in strict liability. If a no-name rewrapper sold a relabeled cell as a fresh consumer battery, the rewrapper and the vape shop step into the chain. Reading the wrap, the can stamp, and the receipt is how the right defendant gets named.
LG Chem has faced multiple suits alleging that its 18650 cells exploded in users' pockets. In one example, a North Carolina resident alleged that two LG cells exploded in his pocket and caused second- and third-degree burns to his leg and knee, with hospitalization and permanent scarring. The complaint alleged LG Chem knew its cells were being used in vapes yet did not warn consumers in time. These allegations have not all been proven, and each case turns on its own proof.
The recurring theme is the loose-cell sale. The cell maker says it never authorized the sale of bare cells to consumers. The seller hands them over anyway. The victim is caught between them, which is why a Florida claim often names both the cell maker and the local seller.
Samsung SDI cells have produced the textbook pocket-burn case. A Minnesota plaintiff alleged that Samsung SDI 18650 cells exploded in his pocket on January 7, 2020, and caused second- and third-degree burns to his genitals, thigh, and hand. The Minnesota Court of Appeals ruled in 2025 that Minnesota courts had personal jurisdiction over Samsung SDI, finding the company sold nearly 3 million 18650 cells into the state and knew since at least 2016 that its cells were going into e-cigarettes.
That jurisdiction ruling matters far beyond Minnesota. It shows that a foreign cell maker can be pulled into a U.S. court when it floods the consumer market with cells it knows are ending up in vapes. A Florida victim with a genuine Samsung SDI cell should preserve it precisely so that the maker can be identified and answered to.
Florida recognizes strict products liability. The Florida Supreme Court adopted it in West v. Caterpillar Tractor Co., 336 So. 2d 80 (Fla. 1976), embracing the Restatement (Second) of Torts section 402A. Under that rule, a seller of a product in a defective condition unreasonably dangerous to the user is liable for the physical harm it causes, even if the seller used all possible care. The victim does not have to prove carelessness. He has to prove a defect that existed when the product left the defendant's hands and that the defect caused the burn.
A vape cell case usually rests on three theories. The first is a manufacturing defect, meaning this particular cell left the line flawed, perhaps with a weak separator or contaminated electrode. The second is a design defect, meaning the cell or the mod was unreasonably dangerous as designed, for example a bare cell with no protection circuit sold for pocket carry, or a mech mod with no short-circuit cutoff. The third is failure to warn, meaning the maker or seller did not tell the user that a loose cell can short on keys and vent flame.
Negligence rides alongside strict liability. A vape shop that sells a loose, rewrapped 18650 to a walk-in customer, with no battery case and no warning, may be negligent. That ordinary negligence claim against a seller carries a two-year deadline under section 95.11(5)(a), Florida Statutes, which is shorter than the four-year products clock, so the negligence theory has to be filed earlier. Florida applies modified comparative fault under section 768.81, Florida Statutes, and a party found more than 50 percent at fault for his own harm recovers nothing.
The clock you face depends on the harm. For a personal-injury product-liability claim from a vape or 18650 explosion, the deadline is four years under section 95.11(3)(d), Florida Statutes. For a claim sounding in ordinary negligence, for instance against a seller for negligent sale, the deadline is two years under section 95.11(5)(a), Florida Statutes. If the explosion killed someone, the wrongful-death deadline is two years under section 95.11(5)(e), Florida Statutes.
These are the current Florida deadlines, and the clock is unforgiving. Miss it and even a strong case is gone before you get to tell it, so the safest move is to call before it runs.
A separate clock can bar an older product outright. The statute of repose in section 95.031(2)(b), Florida Statutes, bars a product-liability action for harm caused more than 12 years after the product was delivered to its first purchaser. A vape device or cell bought many years ago could fall outside the repose window even if the four-year limitations clock has not run. For a victim in southeast Georgia, the analog rules are strict products liability under OCGA section 51-1-11 with a 10-year repose, and a two-year personal-injury limitations period under OCGA section 9-3-33.
In a vape explosion claim, the physical evidence wins or loses everything. The vented cell, the mod, the torn wrap, the charger, and the receipt together prove which maker built the cell, who sold it, and how it failed. Once those items are gone, an expert cannot perform a teardown, and the defense will argue you cannot prove a defect. Do not throw anything away, and do not let a hospital, a fire department, or an insurer keep the remains without a written agreement.
Preserve everything in its damaged state. Resist the urge to clean the cell or to reassemble the mod. A metallurgist or battery engineer reads the vent path, the rupture point, and the wrap residue to tell a manufacturing defect from misuse. Photograph the items from every angle before anyone touches them, and keep them dry and isolated, because a vented cell can still be chemically active.
Build the human record at the same time. Keep the emergency-room chart, the burn-center notes, the surgical and graft records, and photographs of the wound as it heals. Save the box, the listing, and any text or email from the seller or the online store. The chain from a named cell maker, through a named seller, to your skin is exactly what a Florida products case has to show.
More than one party usually shares the blame. The cell maker, such as LG Chem, Samsung SDI, Sony, or Murata, may answer if a genuine cell of its make failed because of a defect. The rewrapper that stripped an industrial cell and relabeled it as a consumer battery steps into the chain when it puts a defective product into commerce. The vape shop or online seller that handed over a loose cell with no case and no warning faces both strict liability as a seller and ordinary negligence.
The mod maker belongs in the analysis when the device contributed. A mechanical mod with no short-circuit protection, or a regulated mod whose board failed, can be a defendant in its own right. The distributor and importer that brought a foreign cell or device into the United States can be liable as members of the distributive chain, which matters when the original maker sits overseas and is hard to reach.
Naming the right defendants takes the physical evidence and the paper trail. The cell stamp identifies the maker. The wrap identifies the rewrapper. The receipt and the listing identify the seller and the importer. This is why preservation comes first and litigation comes second. Graham W. Syfert, Esq., is Of Counsel to the Soud Law Firm, and the firm relationship is a credential, not a promise of any particular result.
I tell burn clients the same thing I tell every client. Save the evidence first and talk to me second. A vented 18650 cell is small enough to lose and important enough to decide the case. Put it in a glass jar, photograph it, and do not let anyone take it without a signed receipt and a written promise to preserve it.
I watch the two-year clocks closely. The four-year products deadline in section 95.11(3)(d) feels generous, but a negligence claim against the seller runs in two years under section 95.11(5)(a), and a wrongful-death claim runs in two years under section 95.11(5)(e). I would rather file early than explain to a family why we lost the seller. I also check the 12-year repose in section 95.031(2)(b) on any older device, because a strong defect claim can still be barred by the calendar.
I am candid about who can actually pay. In one Florida case, a jury awarded a man 21,000 dollars in medical expenses and 15 million dollars for pain and suffering after a vape battery exploded in his pocket and burned his legs, but the selling company was no longer in business, which left collection in doubt. That result was tied to that case's facts and is not a promise about yours. Past results do not guarantee a similar outcome. I look for a solvent defendant in the chain, a cell maker, an importer, or an insured seller, before anyone counts on a number.
If a vape or a loose 18650 cell exploded and burned you in Florida, the first hours and days protect both your health and your claim. Take these steps in order.
You may. If a loose 18650 cell shorted and burned you, Florida allows a product-liability claim with a four-year deadline under section 95.11(3)(d), Florida Statutes. The case depends on preserving the cell so an expert can show a defect. Graham W. Syfert, Esq., is Of Counsel to the Soud Law Firm and can review your facts.
For a product-liability injury claim, four years under section 95.11(3)(d), Florida Statutes. For ordinary negligence against a seller, two years under section 95.11(5)(a). If the explosion killed someone, two years for wrongful death under section 95.11(5)(e). An older device may also be barred by the 12-year repose in section 95.031(2)(b).
Possibly. Both makers say they never authorized selling bare cells to consumers, yet courts have allowed claims to proceed. A Minnesota appellate court ruled in 2025 that it had jurisdiction over Samsung SDI in a pocket-explosion burn case. Whether you can reach the maker depends on identifying a genuine cell of its make, which is why you must save the cell.
Because those cells are industrial components meant to be welded inside sealed battery packs, not sold loose. The U.S. Consumer Product Safety Commission warned on January 8, 2021, that loose cells are stripped from packs, rewrapped, and sold as consumer batteries. Samsung SDI states it does not design or authorize its cells for use in vapes or e-cigarettes.
It can be. A mechanical mod has no circuit board, no voltage regulation, and no short-circuit cutoff, so it offers no protection when a cell fails. A mod that launches its end cap or vents into your hand may be defective in design. The cell maker and the seller can also be defendants in the same case.
Keep them. Do not clean, reassemble, or discard the cell, the mod, the wrap, the charger, or the receipt. The vented cell is the key evidence, and an engineer reads the rupture to prove a manufacturing or design defect. Photograph everything, store the cell isolated and dry, and do not surrender it without a written preservation agreement.
Yes. In October 2021 a South Florida jury awarded a man 21,000 dollars in medical expenses and 15 million dollars for pain and suffering after a vape battery exploded in his pocket and burned his legs. The selling company was no longer in business, which clouded collection. That result was tied to that case's facts. Past results do not guarantee a similar outcome.
Yes. In May 2018 a 38-year-old man in St. Petersburg, Florida, was killed when his mechanical-mod vape exploded and drove pieces of the device into his skull, with burns over much of his body from the resulting fire. The medical examiner listed the cause of death as a projectile wound of the head. A Florida wrongful-death claim has a two-year deadline under section 95.11(5)(e), Florida Statutes.
Yes, a seller can face strict liability for putting a defective product into commerce and ordinary negligence for selling a loose, rewrapped cell with no battery case and no warning. The negligence claim against a seller carries a two-year deadline under section 95.11(5)(a), Florida Statutes, so it must be filed sooner than the four-year products claim.
Florida uses modified comparative fault under section 768.81, Florida Statutes. A defense may argue you contributed by carrying a bare cell with metal. But the seller created that risk by handing over a loose cell with no case and no warning. A party found more than 50 percent at fault for his own harm recovers nothing, so how the cell was sold is central.
