APC PowerStack 450 1U J Compatible Battery

Questions about this item

What is the maximum load the PS450J UPS can sustain before battery runtime becomes the limiting factor?

The PS450J is rated at 450 VA; sustained loads above that level will trip the unit or drain the battery faster than the 9 Ah cells can support.

How much heat does the RBC18 compatible battery kit generate during continuous float charging?

The two 6 V 9 Ah sealed lead-acid cells produce minimal heat while on float charge; normal rack airflow is sufficient to keep temperatures within the manufacturer's specified operating range.
