2.4 ‐‐ Service Maintenance
Zinc Air batteries are stored with adhesive backed tabs prior to use. These tabs seal the air holes against
oxygen and water ingress. To obtain the full battery performance, the tab should be removed only
immediately prior to use. When the battery is sealed by the tab, service loss due to self discharge is
approximately 5% per year. Figure 10 illustrates the rates at which capacity is lost with the tab on and
the tab removed.
