to operate the battery normally. The battery is required to not explode, ignite, vent, or leak. Section 4.4.4 – Operating Altitude GR-3150 operating altitude testing references the latest issue of GR-63-CORE operating altitude criteria. For Level III operating altitude, the battery is float charged per manufacturer’s recommendations, and then exposed to high temperatures and altitude combinations. The battery is required to operate normally and not explode, ignite, vent or leak during and after the testing. Section 4.4.5 – Immersion (Flooded Conditions) There are times when the lower compartments of electronic equipment enclosures in the OSP can become flooded. Floods are normally caused by inclement weather (i.e., heavy storms or high tides). During these events, the batteries normally installed in the lower compartments of the enclosures are either partially submerged or completely immersed in flood water. These flood waters can short the terminals of the battery and also Figure 2: The simulated telecom environmental cycles battery performance and environmental profile Beautiful But more than just a pretty face.
