Lithium Battery Fire Insurance: Will Product Liability Cover the Claim? (2026)

Lithium battery fire insurance, meaning your product liability coverage, generally pays the property damage and injury when a defective lithium-ion battery in your product starts a fire. The catch: carriers increasingly attach a battery exclusion, and the policy never pays to replace your own product. UL certification increasingly decides whether you can place coverage at all.

Here is which policy actually pays, the exclusion to hunt for in your renewal, and how a UL listing affects your coverage.

If my product starts a lithium battery fire, does insurance cover it?

Generally yes, through product liability insurance, which pays the third-party property damage and injury a defective battery in your product causes. A house fire is mostly a property-damage claim, sometimes with bodily injury attached. Two limits matter: the policy never replaces your own defective product, and a lithium-ion exclusion can remove the fire coverage entirely.

A lithium battery fire from your product is the textbook claim product liability was built to handle. Commercial general liability, the policy that most electronics sellers' fire coverage sits inside, pays for third-party bodily injury and property damage caused by something you sold, per the Insurance Information Institute. When a power bank ignites in someone's apartment, the bulk of the loss is the apartment itself. The same coverage handles burns or smoke injuries if a person was hurt.

Now the two catches, because they decide whether a fire claim actually pays. A standard "your product" exclusion means the policy will rebuild the customer's burned home but never cut you a check for the defective device that started it. (That part trips up sellers who assume their own losses are covered too.) A lithium-ion exclusion, which more carriers attach every year, can wipe out the fire coverage you thought you bought, and it gets its own section below. The basic product liability insurance answer holds across most battery products.

Which policy actually pays after a battery fire?

Which policy pays after a battery fire depends on what burned. If a customer's home burns, their homeowner's insurer usually pays first, then subrogates against your product liability policy to recover. If your own warehouse stock burns, your commercial property policy responds. If a customer is hurt, your product liability coverage pays the injury.

Subrogation is the part that catches sellers off guard. It means the victim's insurer pays the victim, then stands in their shoes to recover the money from you. So even with no direct lawsuit from the customer, you can still be pursued, and the demand arrives from an insurance carrier rather than the person who got burned.

One electronics brand we worked with never heard from the customer directly. Months later the first contact arrived: a subrogation demand from the customer's homeowner's insurer after a power bank started an apartment fire. That demand is a textbook battery fire property-damage claim routed through an insurer. For your own stock, your commercial property policy and any inventory and in-transit coverage handle the loss.

Why are carriers adding a lithium-ion exclusion?

Because lithium-ion fires have become frequent and severe, carriers increasingly attach a lithium-ion, thermal-runaway, or battery exclusion to product liability. The exclusion now reaches some excess layers, the policies stacked above your primary coverage. Thermal runaway means a battery cell overheats in a self-feeding reaction. It can be added quietly at renewal without anyone flagging it, so read the policy every year.

There is no single standard form for a lithium-ion exclusion, so treat it as a carrier-by-carrier market trend rather than one industry rule. Some carriers drop the fire coverage outright. Others write it back in for an extra premium once you show a UL test report. The wording hides in plain sight, and most sellers never check, so scan your declarations and endorsement pages for any of these phrases:

• lithium-ion
• thermal runaway
• spontaneous combustion
• electrical hazard
• battery sublimits

The exclusion has also started appearing on excess and difference-in-conditions layers, the policies that fill gaps your primary coverage leaves, so a clean primary policy does not guarantee the layers above it are clean too. One consumer-electronics brand renewed its product liability and assumed nothing had changed. The carrier had quietly attached a thermal-runaway exclusion at the prior renewal, and the brand only found out when a fire claim came in and the carrier denied it. That gap on its lithium-ion product liability turned a covered loss into an out-of-pocket one.

Does my battery product need a UL listing to be covered?

Increasingly, underwriters do require it. They ask for UL certification on battery products, and the right standard depends on the device. UL 2056 covers power banks and UL 2849 covers e-bikes, with UL 2271 for e-bike batteries and UL 2272 for e-scooters and hoverboards. New York City's Local Law 39 bans the sale of uncertified e-bikes and batteries outright.

A UL listing for your battery product does two things for coverage. It moves you toward admitted carriers who would otherwise decline, and it gives your defense a backbone, because you can show you met the recognized safety standard for the device. Local Law 39 took effect in September 2023 and makes uncertified sales illegal in the country's largest e-bike market. UL Standards & Engagement links that law to a drop in fire deaths. UL introduced UL 2056 as the first dedicated power-bank safety standard. Counterfeit or uncertified cells push you the other way, toward harder placement, a fight over whether the fire is even covered, and a weak defense. (If you rebuild or refurbish battery devices, the altered-device rules are their own animal.)

How bad are lithium battery fires, really?

Bad enough that the CPSC is recalling them by the million. Anker recalled about 1,158,000 power banks in 2025 after fires and over $60,700 in reported property damage. Casely recalled about 429,000 power banks tied to one death. One defective power-bank model was linked to a single fire causing $15 million in property damage.

The recall numbers come straight from federal regulators. The CPSC Anker recall logged 19 fires and explosions, and the agency separately warned consumers about a Yiisonger power bank after that single $15 million blaze. The micromobility data runs in the same direction. The FDNY counted 268 e-bike battery fires across New York City in 2023, with 18 deaths and 150 injuries.

This is why carriers treat lithium battery fires as a severity problem more than a frequency one. A single power bank fire claim can run into seven or eight figures once a home and its contents are gone. Insurers price for that tail event, and many simply exclude it. General liability also will not reimburse the recall pull itself, which is where a separate product recall insurance policy covers the cost of yanking inventory off shelves.

What should an electronics seller buy, and what does it cost?

An electronics seller should buy product liability rated for lithium-ion products with no battery exclusion, add product recall coverage, and carry commercial property for their own inventory. Electronics with lithium is a higher-risk class, so coverage often sits on specialty or surplus-lines paper and prices above general product lines. Confirm there is no lithium exclusion before you bind.

Surplus lines means non-standard carriers that write risks standard insurers decline, which is where most lithium electronics land. In our experience placing battery products, standalone product liability often starts around $3,000 for higher-risk electronics, and a rough rule of thumb is about 0.25% of product sales. The buy list:

• Product liability with no lithium-ion or thermal-runaway exclusion
• Product recall coverage
• Commercial property or inventory coverage for your own stock
• UL certification on file for the device you sell
• Additional-insured status from your cell supplier, meaning their policy is named to back yours

Coverwatch reads the policy form for lithium-ion and thermal-runaway exclusions before you bind. It places battery products across 60+ carriers including specialty markets, so a fire claim is covered rather than quietly carved out. (This is the step most sellers skip until a subrogation letter lands.) Pull your product liability declarations page and search it for "lithium."
