Wales (Wales Times) September 17, 2026 – The service has warned residents about an increase in lithium-ion battery fires in recent weeks and urged people to take extra care when charging and storing devices powered by the batteries.

The warning covers a wide range of everyday products, including mobile phones, laptops, e-bikes, e-scooters and power tools. Although lithium-ion batteries are generally safe when used correctly, the fire service said batteries that are damaged, faulty or improperly charged can fail without warning and cause serious fires.

The warning was reported by LeaderLive in an article titled “Fire service warns of rise in lithium-ion battery fires”. The report did not identify a specific number of incidents, locations or injuries linked to the recent increase. It did, however, relay advice from North uk/fire/">Wales Fire and Rescue Service about reducing the risk of battery-related fires in homes and other buildings.

What has North Wales Fire and Rescue Service said?

Jane Honey, deputy head of prevention at North Wales Fire and Rescue Service, said lithium-ion batteries are now used in many ordinary household and personal devices.

As reported by LeaderLive, Honey said:

“Lithium-ion batteries are used in many everyday items, including mobile phones, laptops, e-bikes, e-scooters and power tools.”

She said the batteries are generally safe when properly used, but warned that damaged, faulty or improperly charged batteries can fail without warning. According to the service, such failures can result in serious fires, making the way devices are charged, stored and maintained an important safety consideration.

The warning applies not only to larger batteries used in e-bikes and e-scooters but also to smaller batteries found in phones, computers and other electronic equipment. This means that many households may have several lithium-ion battery-powered devices in use or charging at the same time.

How can people reduce the risk of a battery fire?

The fire service has advised residents to use the charger supplied or recommended by the device manufacturer. Using the correct charger is intended to reduce the risk associated with incompatible charging equipment or unsuitable power supplies.

Residents have also been told to avoid overcharging batteries. The service’s advice is particularly relevant when devices are left charging for long periods or when charging takes place without anyone nearby to notice signs of overheating or damage.

North Wales Fire and Rescue Service has further advised people not to charge devices in or near escape routes, including hallways and exits. Keeping charging equipment away from these areas can help preserve a route out of a property if a fire occurs.

The main safety advice reported by LeaderLive is:

• Use the manufacturer’s charger.
• Avoid overcharging batteries.
• Do not charge devices in or near hallways, exits or other escape routes.
• Stop using a battery immediately if it shows signs of damage.
• Treat overheating, swelling and unusual smells as warning signs.
• Dispose of unsafe batteries safely.
• Do not attempt to tackle a battery fire yourself.
• Leave the building and call 999 immediately if a fire occurs.leaderlive.co

Which warning signs should users look for?

North Wales Fire and Rescue Service has identified several signs that may indicate a battery is unsafe. These include visible damage, overheating, swelling and unusual smells.

A damaged battery should not continue to be used or charged. The same applies to a battery that becomes unusually hot, changes shape or produces an unfamiliar odour. The service has advised people to stop using such batteries immediately and arrange safe disposal.

The warning is important because a battery may present a fire risk even if the device itself appears to be functioning normally. Residents should therefore avoid ignoring physical changes or unusual behaviour during charging or use.

The fire service has not advised people to stop using lithium-ion products altogether. Instead, its guidance focuses on correct use, careful charging, safe storage and prompt action when a battery shows signs of failure.

What should people do if a lithium-ion battery catches fire?

People should not try to tackle a lithium-ion battery fire themselves, according to North Wales Fire and Rescue Service.

Anyone who discovers a fire should leave the property or immediate danger area and call 999. The service’s warning is intended to prevent residents from placing themselves at risk by attempting to deal with a fire involving a battery-powered device.

Maintaining clear escape routes is therefore a central part of the advice. Charging devices in hallways, near doors or close to exits could obstruct or endanger the route people may need to use during an emergency.

Households should also ensure that everyone knows how to leave the property and contact emergency services. The service’s instruction is straightforward: leave and call 999 rather than attempting to handle the fire.

Why are e-bikes and e-scooters part of the warning?

E-bikes and e-scooters are among the devices named by North Wales Fire and Rescue Service as using lithium-ion batteries. Their batteries are often larger than those found in mobile phones and may store considerable energy.

The service’s general advice applies to these products in the same way as it applies to laptops, phones and power tools. Owners should use appropriate charging equipment, avoid overcharging and stop using batteries showing damage, overheating, swelling or unusual smells.

The report did not provide separate figures for fires involving e-bikes, e-scooters or other individual product categories. It also did not state whether the recent increase was concentrated in one type of device. The available warning concerns lithium-ion battery fires as a wider category.

What has the fire service not confirmed?

The report confirmed that North Wales Fire and Rescue Service has seen an increase in lithium-ion battery fires in recent weeks. It did not state the total number of fires, the percentage increase or the precise period covered by the service’s observation.

It also did not name individual incidents, properties or manufacturers. No specific cause was attributed to the reported rise beyond the general risks associated with damaged, faulty or improperly charged batteries.

The information available therefore supports a public safety warning rather than a detailed statistical assessment. Residents have been given preventive guidance, but the report does not establish how the fires are distributed across North Wales or which devices are most frequently involved.

What does this warning mean for households?

The warning means households should review where and how they charge battery-powered devices. A phone, laptop, e-bike, e-scooter or power tool should not be charged in a place that could block an exit or make escape more difficult.

People should also inspect batteries and charging equipment regularly. A battery that becomes swollen, unusually hot, damaged or associated with an unusual smell should be taken out of use rather than repeatedly tested or recharged.

The advice is preventive, but it also addresses what to do in an emergency. If a fire starts, residents should prioritise getting out and contacting emergency services. The service has specifically warned against trying to put out the fire personally.

Why has the fire service issued the warning now?

North Wales Fire and Rescue Service issued the warning after reporting an increase in lithium-ion battery fires in recent weeks. The service’s deputy head of prevention used the development to remind residents that these batteries are present in many common devices.

The timing reflects the service’s observation of recent incidents, although the available report does not give detailed incident data. The central message is that safe charging and storage practices can help reduce the risk of a potentially serious fire.

The service’s guidance also places responsibility on users to recognise warning signs. Damage, overheating, swelling and unusual smells should not be treated as normal features of battery operation.

What should users of rechargeable devices do next?

People who use rechargeable devices should check that they are using the manufacturer’s charger and that the device is not being left to charge in a hallway, beside an exit or in another escape route.

They should also examine batteries for visible damage and stop using any battery that is swollen, overheating or producing an unusual smell. Unsafe batteries should be disposed of through an appropriate process rather than placed in ordinary household waste.

Most importantly, residents should not attempt to fight a battery fire. The advice from North Wales Fire and Rescue Service is to leave immediately and call 999.leaderlive.co

What is the background to lithium-ion battery fires?

Lithium-ion batteries are rechargeable batteries used in many portable electronic products and electrically powered devices. North Wales Fire and Rescue Service said they are found in mobile phones, laptops, e-bikes, e-scooters and power tools.

The service said these batteries are generally safe when used correctly. However, it warned that damage, manufacturing faults or improper charging can lead to failure and serious fires.

The latest warning follows the service’s report of an increase in lithium-ion battery fires in recent weeks. LeaderLive attributed the safety advice to Jane Honey, deputy head of prevention, and reported the service’s recommendations on charging, storage, warning signs and emergency action. The report did not include a numerical breakdown of incidents or identify particular manufacturers.leaderlive.co

How could the warning affect North Wales residents?

The development is likely to encourage households across North Wales to pay closer attention to rechargeable devices and their charging arrangements. Residents who own e-bikes, e-scooters, laptops, phones or power tools may review whether batteries are charged with the correct equipment and kept away from escape routes.

For families, the warning may also increase awareness of the need to act quickly when a battery becomes hot, swollen, damaged or develops an unusual smell. The practical effect is not a requirement to stop using lithium-ion devices, but a reminder to use them according to the manufacturer’s instructions and remove unsafe batteries from service.
