23、s. These batteries consist of either a single electrochemicalcell or two or more cells connected in series, parallel, or both, that convert chemical energy into electricalenergy by chemical reaction.1.2These requirements are intended to reduce the risk of fire or explosion when batteries are used in
24、 aproduct. The proper use of these batteries in a particular application is dependent on their use in acomplete product that complies with the requirements applicable to such a product.1.3 These requirements are intended to cover batteries for general use and do not include thecombination of the bat
25、tery and the host product which are covered by requirements in the host productstandard.1.4 These requirements are also intended to reduce the risk of injury to persons due to fire or explosionwhen batteries are removed from a product to be transported, stored, or discarded.1.5 These requirements do
26、 not cover the toxicity risk that results from the ingestion of a battery or itscontents, nor the risk of injury to persons that occurs if a battery is cut open to provide access to itscontents.2 General2.1 Lithium cells2.1.1 In lieu of the requirements outlined in Table 6.1 cells constructed of lit
