Fire destroys two cars in Lahti, Finland after incorrect jump-starting procedure

Modern vehicles should not be jump-started independently if the battery is dead, as the increasing technology in cars also affects their electrical safety. In Lahti, Finland, two cars were destroyed by a fire that originated from an incorrect jump-start. Jari Rekola, a system specialist at Renkomäki Autoexpert, noted that while such incidents are not very common, they do occur when jump-starting goes wrong. Common issues include blown fuses due to short circuits, but severe damage can also happen from voltage spikes, which can be expensive to fix.

Rekola explained that while older cars allowed direct connections to the battery terminals, modern vehicles may even have manufacturer prohibitions against this practice. Drivers should refer to the owner’s manual for proper jump-starting procedures. The Finnish Automobile Association advises seeking professional help if a battery is flat. Teppo Vesalainen, the association’s training manager, emphasized that even slight errors in jump-starting can lead to costly damage or even fires.

Battery problems are among the top three issues that cause motorists to seek roadside assistance, especially during extreme cold or heat. Vesalainen urged drivers to contact a roadside service or their insurance company for help, as professionals generally carry liability insurance for any damages incurred during service.

Electric vehicles also have batteries that may require jump-starting. Alongside a 12-volt battery, they feature a high-voltage battery essential for driving, and a malfunction in the smaller battery can render the vehicle inoperable. Checking battery condition before the winter season is advised to avoid supply shortages during peak demand. Installing a battery heater and maintenance charger can help ensure battery readiness in cold temperatures.
