Lithium Intrinsically Safe Overview

Intrinsically Safe.
Safety is vitally important when working in hazardous conditions. Intrinsic safety is the globally
recognized protection technique designed to ensure safe operation of electronic devices in potentially
explosive environments by eliminating the potential for ignition.
Energizer® Application Support is proud to announce Energizer® Ultimate Lithium AA
and AAA batteries are now certified as a component in intrinsic safety apparatus
according to UL 913 and Directive 94/9/EC ATEX. This means that the world’s longest
lasting battery in high tech devices can readily be used in these applications.
