A regulatory term referring to a battery that is specifically designed to supply electric power for starting, lighting.
Starting, lighting and ignition battery / SLI battery is the category for batteries designed to supply starting, lighting, or ignition power and auxiliary or backup power in vehicles, transport, or machinery.
Regulation (EU) 2023/1542 concerning batteries and waste batteries
a battery that is specifically designed to supply electric power for starting, lighting, or ignition and that can also be used for auxiliary or backup purposes in vehicles, other means of transport or machinery;
Reference: Article 3, point 12
Battery Regulation obligations vary by category. SLI batteries are subject to core product, labeling, and QR/data-carrier obligations, and they are relevant to due-diligence obligations, but they do not sit in the same battery-passport and carbon-footprint tier as EV batteries and in-scope industrial batteries.
This term matters when conventional vehicle or machinery batteries need to be separated from EV, LMT, industrial, and portable battery categories.
For Minespider, SLI battery is a vehicle-support category term for routing battery evidence correctly.
