Energizer L91 Ultimate Lithium is a disposable 1.5V nominal AA battery with the largest capacity available on the market and extreme durability (over 20 years) and low temperature resistance. It is particularly suitable for high current draws where its capabilities are fully demonstrated.
This battery is designed to operate in Fenix E12, E20 V2.0, LD12R, LD22, CL23 or Fenix headlamps HM23, HM23 V2.0, HL30, HL50 and HP16R.
Caution: cannot be used in flashlights and headlamps that also support 2x Li-ion 14500 (Fenix HL35 and Fenix E25 Ultimate Edition).
