Drivers warned against unsafe jump-starting practices in Lahti after car fire incident

Drivers are advised not to jump-start modern vehicles independently if the battery is dead, as the increasing technological complexity in cars affects their electrical safety. Recently, two cars were destroyed in a fire in Lahti, triggered by an improper jump-start attempt. Jari Rekola, a systems expert at Renkomäki Autoexpert, notes that while such incidents are infrequent, they do occur, often due to short circuits that can lead to fuse damage or more severe issues like voltage spikes resulting in expensive repairs.

In older vehicles, jumper cables could be connected directly to the battery, but this may be prohibited or unsafe in modern cars. The vehicle’s manual can provide guidance on whether jump-starting is permitted and how to do so safely.

The Finnish Automobile Association recommends consulting professionals when dealing with battery issues. Teppo Vesalainen, the training manager, emphasizes that even small errors can cause costly damage to sensitive electronic components or, in worst-case scenarios, fires.

Battery issues rank among the top three reasons drivers need assistance on the road, especially during extreme temperatures. Vesalainen advises contacting roadside assistance or insurance companies for jump-start services, as professional services generally carry liability insurance to cover any damages incurred during the process.

Electric and hybrid vehicles also require careful handling of their dual battery systems. Issues with the 12-volt battery can render these vehicles inoperable, even if the main battery is charged. Both the Finnish Automobile Association and local repair shops recommend checking battery health before winter arrives, as demand for batteries may outstrip supply during severe cold spells. Additionally, installing battery heaters and maintenance chargers can help ensure battery readiness in colder conditions.
