1.3‐‐FeaturesofZincAirPrismatic

Energizer’sZincAirPrismaticbatteriesoffera 5mmthin,prismaticconstructiondesignedtoworkwitha
variety of applications.This shape is consistent with the low profile design of today’s devices, often
requiring a thinner battery solution.The thinnest round cell available is the AAAA battery at
approximately8
mm,andmanyLithiumIonrechargeablesolutionshaveathicknessof5mm.

Energizer Zinc Air Prismatic batteries also offer the opportunity to significantly lower manufacturer
costs.It is likely that the cost of a Zinc Air Prismatic battery solution will be less than the cost of a
LithiumIon
battery.AddingtothecostofaLithiumIonsolutionisthecostofcircuitryforchargeand
dischargecontrol,whichisnotneededwithZincAirPrismaticbatteries.FurthermoreZincAirPrismatic
batteriesarereadytobeusedoutofthepackage.Thereisnoneedforchargeadaptors.

This service advantage is due to Zinc Air technology offering the highest energy density for non‐
