AMI suggests li-ion battery safety awareness needed

Battery related fire claims points to a need for consumer safety awareness, says AMI.

Its data shows at least one home insurance claim is lodged monthly for fire damage caused by lithium-ion batteries and their charging systems.

This trend has continued at a similar rate since AMI last reported on battery caused blazes in 2021, following a surge in claims.

“Consumers should be mindful of reputable battery production when purchasing electrical products,” says AMI claims executive general manager Wayne Tippet.

“There is nothing inherently dangerous about lithium-ion batteries, so long as they are treated correctly, and basic safety measures are followed,” he explains.

“Our data shows that lithium-ion batteries have become predominant over the last decade as they are found in an increasing number of everyday products, including phones, laptops, headphones, smart watches, children’s toys, tools, electric cars, bikes, and scooters.

“These batteries are very useful because they hold more energy, so they can last longer, and they charge faster than regular batteries,” says Tippet.

“However, for many consumers, lithium-ion batteries are newer technology, and so it is important to make sure you are using them safely.”

He says AMI’s data is also a reminder to check an insurance policy and ensure coverage in the event of a lithium-battery powered device starting a fire.

Fires generally start with the battery overheating.

“We have seen cases of chrome books, e-bikes and e-scooters going up in flames or even exploding after being left on charge,” says Tippet.

Lithium-ion battery fires tend to be more severe and can lead to serious damage, he adds.

“Three of the main causes we’ve seen are defective parts, incorrect charging, and mistreatment.”

Defective parts often come in poorly produced items bought from cheaper and less reputable manufacturers, says Tippet, noting correctly matched chargers are far less likely to overheat.

“You should never use a charger that did not come with the device or use it in a way that does not meet the manufacturer’s instruction,” he explains.

“When charging electronic devices such as phone or tablets, do not place them on soft surfaces and do not leave devices on charge on for extended periods of time.

“It is also important to note that it is the battery itself that catches fire; not the device the battery is found in.

“We have seen media coverage citing the incidence of battery related blazes as a reason not to buy electric vehicles or e-bikes,” says Tippet.

“The boost in consumer interest in electric cars, bikes and scooters over the last few years is an excellent shift to help reduce transport emissions.

“The takeaway is not that these products or their batteries are inherently dangerous, but a reminder of steps that consumers can take to protect themselves.

“AMI will continue to insure e-bikes and scooters, electric and hybrid cars, mobile phones and laptops.”

The last EVs and Beyond magazine also carried battery and charging safety tips from electric scooter expert Jonno Leonard.

AMI suggests using only the charger specifically designed for the battery, not overcharging the battery by leaving it unattended for a prolonged period, keeping watch while the battery is being charged and removing it immediately if it starts to feel hot, avoiding li-ion battery exposure to extreme temperatures, punctures, crushing, or damaging the battery casing; and disposing of batteries carefully – generally at a recycling location (contact the local council) rather than putting household waste.

The insurer also recommends following the manufacturer’s guidelines for proper use, storage, and disposal of li-ion batteries, using care in the treatment of chargers and charging cables – regularly checking cables for signs of wear such as loose plugs, exposed wires, or breaks – storing li-ion batteries in a cool, dry place and keeping them away from moisture and flammable materials.

Don’t use damaged or visibly degrading li-ion batteries and dispose of them properly, and when charging items in a garage or workshop, keep batteries away from flammables and areas where they could get damp, says AMI.

Safety tips for EV, e-bike and e-scooter charging include storage and charging in a garage, shed or carport, away from living spaces, exit doors, escape routes and combustible materials. 

Only use electric vehicle charging adaptors supplied by the vehicle manufacturer or by an electric vehicle supply equipment (EVSE) manufacturer, don’t use any household adaptor (such as a multi-box, double plug or a travel plug) between EVSE such as an In-Cord Control and Protection Device IC-CPD and a socket outlet; never use damaged or modified charging equipment such as overseas equipment that has been fitted with a New Zealand plug, and don’t use any faulty charging equipment – get it checked by the manufacturer, AMI adds.
