3.3‐‐BatteryCompartment
The design ofa Zinc Air Prismatic battery compartment depends on several factors including battery
dimensions, battery orientation, and air flow needed to maintain power to the device.Other
considerationsaretheeaseofbatteryinsertionandremoval,contactmaterials,reversalprotection,and
