Discharge Time (hrs)
The impedance of Energizer Zinc Air Prismatic batteries is higher than similar volume Alkaline batteries, and it decreases slightly through the life of the battery. The impedance should not impact battery performance at low to moderate discharge rates. At higher rate discharges, this higher impedance will reduce operating voltage and delivered energy.
1.4 ‐‐ Zinc Air Prismatic Battery Sizes
Energizer Zinc Air Prismatic batteries provide an ideal form factor for devices with a thin profile. The family of battery sizes is shown in Figure 5, ranging from AAA Alkaline volume equivalent to ½ the AAAA Alkaline volume equivalent. Energizer Zinc Air Prismatic battery nomenclature is determined by the IEC standard. The first ‘P’ indicates Zinc Air chemistry, the second ‘P’ indicates the prismatic form factor, the first two digits represent the diagonal in mm, and the last digit is the battery height in mm. For example the PP355 has a 35 mm diagonal distance and a height of 5 mm.
