Aviva has reported a 7% rise in customer claims over the past year related to fires caused by lithium-ion batteries, which are commonly found in rechargeable devices such as e-bikes and e-scooters. This data, which covers fire claims from 2022 to 2023, includes several alarming incidents. For instance, one significant house fire was initiated by an e-cigarette being charged with an incompatible charger. In another case, a fire caused extensive damage to a house after an e-bike with a second-hand battery was left charging unattended in a bedroom.
Additional incidents included a phone exploding during charging after becoming wet, an annexe being destroyed by a fire ignited by unattended charging batteries, and a garage fire resulting from a faulty charger used on a remote control car. These examples underscore the potential hazards associated with lithium-ion batteries.
Further research commissioned by Aviva indicates a concerning trend in fire safety. The study revealed that one in nine individuals has experienced a fire or explosion at home due to a lithium-ion battery or device. Furthermore, nearly one in ten respondents reported scorching of surfaces where a lithium-ion battery was charging, while two in ten individuals experienced overheating of a battery or device.
This data highlights the increasing risks associated with lithium-ion batteries and the importance of proper charging practices. Aviva’s findings serve as a warning for consumers to be cautious and ensure that they use compatible chargers and monitor their devices while charging to prevent dangerous incidents.
The insurer has pointed out a concerning lack of awareness regarding the risks associated with lithium-ion batteries, which are commonly found in many everyday devices. According to recent research, 41% of respondents do not even know what a lithium-ion battery is, indicating a significant gap in public understanding. Furthermore, 42% of individuals surveyed are unaware of the fire hazards linked to charging these batteries, which can lead to dangerous situations if not properly managed.
Alarmingly, a large majority, approximately 71%, cannot identify the warning signs that indicate a lithium-ion battery may be failing. These signs can include overheating during use, a noticeable decline in performance, and physical changes such as bulging or leaking. Recognising these warning signs is crucial, as they can help prevent potential incidents before they escalate into serious fires.
The lack of awareness extends beyond just the batteries themselves; it also encompasses the devices that utilise lithium-ion technology. Just over a third of adults (37%) were able to correctly identify mobile phones as containing lithium-ion batteries, while 33% recognised laptops. Only 22% identified tablets and vapes, and awareness was even lower for tools and devices such as power tools (23%), smart home devices like doorbells (20%), and electric toothbrushes (17%).
This limited knowledge highlights the urgent need for educational initiatives focused on lithium-ion batteries and their associated risks. By raising awareness, individuals can be better equipped to manage these devices safely, which in turn could help prevent potential fire incidents in homes and workplaces. The insurer emphasises the importance of understanding how to handle lithium-ion batteries properly, ensuring that users are aware of both the benefits and risks associated with these commonly used power sources.
An Aviva spokesperson emphasised, “For most users, devices powered by lithium-ion batteries, including mobile phones, laptops, power tools, and e-bikes, are typically safe when used correctly. However, it is important to recognise that these batteries can present significant fire risks under certain conditions, such as when a battery fails, is faulty, or is charged improperly.
“With the increasing trend of consumers purchasing lithium-ion batteries and devices from second-hand retailers or sellers, the potential for acquiring damaged or faulty batteries has also risen. This situation is further complicated by the possibility that the battery within a device may not be the original manufacturer’s version or that the charger provided is not the correct one for the specific battery type. These factors can contribute to dangerous charging situations.
“Fires caused by lithium-ion batteries can have devastating consequences for both properties and individuals. The nature of these fires can make them particularly challenging to extinguish, often resulting in extensive damage and loss. Therefore, we urge customers to stay informed about the fire risks associated with lithium-ion batteries.
“We encourage all users to adopt precautionary measures, such as using only the correct chargers for their devices, avoiding overcharging, and regularly inspecting batteries for signs of damage, such as overheating, poor performance, or physical deformities like bulging or leaking. By remaining vigilant and informed, consumers can significantly reduce the likelihood of incidents and protect themselves and their properties from potentially catastrophic outcomes.”
