Product Description
Energizer LN91 lithium AA batteries use lithium/iron disulfide (Li/FeS₂) chemistry, providing superior energy density, lightweight construction, and a longer-lasting power supply compared to alkaline alternatives. Rated as FR6 by IEC and LN91 by Energizer’s industrial line, these batteries are direct replacements for standard AA cells but built to withstand rugged conditions and prolonged use cycles.
LN91 batteries maintain a stable voltage throughout the discharge cycle and deliver reliable output even in extreme environments, making them suitable for remote deployments, emergency systems, and critical instrumentation.
