Why didn't the battery provide expected runtime on my Allen-Bradley Bulletin 1609 UPS?

If the battery of your Allen-Bradley UPS doesn't provide the expected runtime, try charging the batteries for 8 hours and then retest. If the runtime is still less than expected after charging, it's time to replace the batteries, even if the Replace Battery LED is not illuminated. This is often due to weak batteries or the end of their lifespan.
