Fire Prevention Week: Safer Battery Charging at Home in Sheboygan

Fire Prevention Week runs October 4 to 10, 2026, and this year the National Fire Protection Association (NFPA) is again focused on lithium-ion batteries. Its 2026 campaign, “Charge into Fire Safety,” is about everyday charging habits. That fits what we see in homes around Sheboygan and the rest of Sheboygan County: more batteries than ever, charging in more places, often on whatever outlet happens to be closest.

Think about how many rechargeable things are in a typical house now. Phones, tablets, and laptops. Cordless drills and leaf blowers. Kids' scooters, e-bikes, and ride-on toys. Robot vacuums and power banks. Most of the time they charge without a problem. But a failing battery can overheat fast, and where and how you charge it makes a real difference.

The NFPA's charging basics

The NFPA's 2026 tip sheet boils safe charging down to a few habits:

• Use the right charger. Stick with the cord and charger that came with the device, or one the manufacturer approves. Cheap off-brand chargers may not meet safety standards and can damage the battery.
• Unplug when it's full. Leaving a device plugged in adds heat and stress on the battery.
• Charge on a hard, flat surface. A table, desk, or bare floor lets heat escape. Beds, pillows, and couches trap it.
• Stop if it feels wrong. If a device gets very hot, swells, smells strange, leaks, smokes, or pops or hisses, stop using it.
• Charge big batteries outside when you can. E-bikes, scooters, and power tool batteries store more energy, so a failure can grow quickly. Don't charge them where they'd block a way out of the house.
• Buy listed products. Look for a mark from a testing lab such as UL, ETL, or CSA.

You can read the full list on the NFPA Fire Prevention Week page.

Where the wiring comes into it

Battery safety is mostly about the battery and the charger. But the outlet and circuit behind them matter too, and that's the part an electrician looks at.

Plug chargers straight into the wall. A charging station built from a power strip plugged into another power strip, or an extension cord running across the garage to a tool charger, puts more load on light-duty cords and connections than they were made for. If you need more outlets where you charge, that's a sign to add them, not to stack adapters.

Watch for warm outlets and loose plugs. An outlet or cover plate that feels warm, looks discolored, or won't grip a plug tightly anymore has a connection problem. Chargers that sit in the same outlet every day make this a common spot for it to show up. Stop using that outlet and have it checked.

Think about the garage. Many people charge e-bikes and tool batteries in the garage, which is reasonable since it keeps them out of the living space. But garage outlets often share a circuit with the door opener, lights, and a freezer. Add a big charger or two and the breaker may start tripping. Our post on the garage chest freezer explains why that circuit can already be working hard, and our guide to why a breaker keeps tripping walks through what a trip is telling you.

Older homes need a closer look. In older Sheboygan homes we still find two-prong outlets, worn receptacles, and wiring that was never meant for today's loads. If your home has aluminum branch wiring, read our aluminum wiring safety post before adding new charging spots.

Smoke alarms are still the backstop

The NFPA tip sheet ends with the same reminder every year: working smoke alarms and a home fire escape plan make a life-saving difference. Fire Prevention Week is a good time to press the test button on every alarm, and to make sure there's one near where you charge things overnight. If your alarms are hardwired and getting old, our post on hardwired smoke and CO alarms covers what to look for.

A quick charging check you can do this weekend

Walk through the house and look at every place something charges:

1. Is it on a hard surface, away from bedding and couch cushions?
2. Is the charger the original or a manufacturer-approved one?
3. Is it plugged straight into the wall, not into a chain of strips or a long cord?
4. Does the outlet feel cool, hold the plug firmly, and show no discoloring?
5. Is there a working smoke alarm nearby?

If you find warm outlets, scorch marks, breakers that trip when chargers run, or simply not enough outlets where you need them, that's a job for an electrician. Our electrical safety checklist is a good companion to this list, and a home electrical inspection can catch problems you can't see from the outlet.
