A flooded lithium golf cart battery is the most dangerous part of a storm-damaged cart. Lithium-ion packs hold a lot of energy in a small space, and water damage, especially from saltwater, can set them up to overheat and burn. That can happen right away, or long after the cart looks dry and harmless.
Here's why the risk exists, what to watch for, where the cart should sit and who to call.
Can a lithium golf cart catch fire after a hurricane?
Yes. In the weeks after Hurricane Ian in 2022, Jimmy Patronis, then Florida's Chief Financial Officer and State Fire Marshal, warned that lithium-ion batteries in electric vehicles, golf carts and scooters could catch fire after saltwater exposure. His office confirmed eight electric vehicle fires caused by saltwater intrusion. After Hurricane Idalia in 2023, Palm Harbor firefighters in Pinellas County issued a similar warning when two flooded electric cars caught fire.
In a letter to Florida's fire marshal after Ian, the National Highway Traffic Safety Administration (NHTSA) noted that flood-damaged EV batteries have ignited several weeks after the damage. A lithium golf cart fire after a hurricane can follow the same delayed pattern, so a cart that seems fine on day three still deserves caution on day thirty.
Many golf cart packs use lithium iron phosphate (LiFePO4) cells, which are generally more heat-tolerant than many car batteries, but no lithium pack is safe to trust after soaking in seawater.
Why golf cart battery saltwater exposure is so dangerous
A lithium golf cart battery is a group of cells managed by a battery management system (BMS) that tracks voltage and temperature. Seawater conducts electricity well. When it gets inside the pack, it can create short circuits between cells and connections, and corrode the BMS board meant to protect it.
Drying doesn't fix it. Evaporating seawater leaves salt behind, and those deposits can form conductive bridges between cells and terminals. A short that heats one cell can push it into thermal runaway, a chain reaction where each overheating cell heats the next. Florida's fire marshal warned that once these fires start, they can keep reigniting.
Warning signs of a damaged lithium battery
Check the cart from a distance a couple of times a day for the next several weeks. Watch for:
- Smoke or vapor from the battery area, even a small amount
- Hissing, popping or crackling sounds
- A sharp, sweet or chemical smell
- Heat coming off the seat or battery cover
- A swollen, bulging or cracked battery case
- Melted plastic, discoloration or leaking fluid
If you see smoke or flames, or hear hissing or popping, get everyone away from the cart and call 911. Tell the dispatcher it's a lithium-ion battery, and don't try to fight the fire yourself.
Where to park a flooded lithium golf cart
The garage is the worst place for it, because a battery fire there can spread to the house. If you can move it safely, without turning it on or wading through water, get it outside and away from anything that can burn.
- NHTSA advises keeping flood-damaged electric vehicles at least 50 feet from structures, other vehicles and combustibles. That's a sensible target for a lithium cart too.
- Pick bare concrete, gravel or dirt, clear of dry grass, fences, sheds and carports.
- Flip the Run/Tow switch, if the cart has one, to Tow before pushing it, or have it towed by someone who knows it has a lithium battery.
If it's stuck in the garage or already showing warning signs, leave it, keep people out and call the fire department (911 if it's smoking).
Don't charge it, and don't open it
Don't plug in a flooded lithium cart, even to see whether it takes a charge. Charging pushes energy into a pack that may already have internal shorts. Don't open the battery case, pull modules or test cells either. The State Fire Marshal's post-Ian warning specifically said not to charge submerged vehicles or open their battery packs.
If there's a main disconnect switch you can reach without touching the battery case, turning it off is reasonable.
Who to call about a flooded lithium golf cart battery
- 911 for smoke, fire, hissing, popping or swelling.
- Your fire department's non-emergency number for advice on isolating the cart.
- Your insurance company, before anything is removed or repaired.
- The battery maker or the shop that installed the pack, for model-specific guidance.
- A buyer or recycler experienced with damaged lithium batteries, if you don't plan to repair the cart.
Never put a lithium battery in the trash or on the curb with storm debris; it belongs at a facility that handles lithium-ion batteries.
Why it matters who hauls the cart away
A flooded lithium cart has to be loaded, transported and stored by people who understand the risk. A pack that gets banged around on a trailer, parked in a crowded building or charged by someone hoping to flip the cart can start a fire. Before you sell, ask the buyer how they move and store damaged lithium carts and what happens to the battery afterward.
We have experience handling lithium-ion carts, damaged packs included, and we send batteries to be recycled responsibly.
What about flooded lead-acid batteries?
Lead-acid batteries don't carry the same delayed fire risk, but they still need care after a flood:
- Battery makers warn that saltwater mixing with battery acid can release chlorine gas, which is toxic. Keep the area ventilated and leave the cell caps on.
- Wet, salty battery tops and terminals can short, causing sparks and heat.
- Charging lead-acid batteries gives off hydrogen, which is flammable, so don't charge a flooded set.
- Cracked cases can leak sulfuric acid. Wear gloves and eye protection.

A flooded lithium golf cart battery deserves more respect than almost anything else after a storm. Keep it outside and away from buildings, don't charge it, check on it for weeks, and call 911 if it smokes. If you'd rather hand the problem to someone equipped for it, you can sell your flood-damaged lithium golf cart as-is, and we'll handle pickup.
