Who May Be Responsible for Your Injury Under Illinois Law
The battery that hurt you reached you through a chain of businesses: the battery cell maker, the device manufacturer, an importer, a distributor and a retailer. Depending on the setting, a property owner or an employer may also be part of the picture. Section 13-213 of the Illinois Code of Civil Procedure describes a product liability action as one brought against "the seller of a product," and it lists sources of harm including manufacture, design, testing, labeling and "warning or instruction regarding any product."
A defect is a flaw that makes a product unreasonably dangerous, and three kinds come up most often. A design defect is a problem built into every unit, such as a pack without adequate protection against overheating or a weak battery management system (the electronics meant to keep cells within safe limits). A manufacturing defect affects a unit that departed from its design. A warning defect is a missing or inadequate instruction or warning.
A strict liability claim asks whether a defect existed and caused your injury. A negligence claim asks whether there was a duty of care, a breach of it, causation and damages. The answers depend on the facts. An injury does not prove fault, and a fire on its own does not establish a defect. Likewise, a recall is not a defect finding, an incident report is not proven causation, a lawsuit is not a liability finding, and an allegation is not a fact.
For you, the practical question is who, if anyone, can be asked to answer for the harm, and the brand, model and seller of the battery are often where that answer begins. If a recall may be involved, the site's lithium battery recall lookup explains how to read a recall notice.
