Summary: This product from the day I purchased it failed to charge normally. It was always slow to recover its charge from power losses of even less than 5 minutes. Recently after a loss of 30 minutes the battery drained to 50%. 48 hours later the battery was completely drained and is not charging. The unit is 18 months old and power losses are infrequent (2-3 times a year) in my area.
Summary: I purchased this unit to replace a SmartUPS unit that died. To my dismay, this unit is not compatable with my computer, which has PFC (Power Factor Correction.) The only remedy APC has is to either return the unit to where it was purchased, or purchase a SmartUPS unit. My issue is the fact that nowhere on APC's website does it mention an incompatability with PFC computers or how to identify them. Most consumers won't even know what it is let alone how to identify it.
Summary: This UPS replaced a 1000 watt unit, but it can't keep the server running during a power outage. With only the server on it, drawing 140 watts, it can keep supply enough power during a self-test or actual power failure. The fan on the unit is loud too. I wish I had purchase a UPS locally, now I've got to call APC, hopefully ship the unit back and go through all the other return hassles.
Summary: Ordered the SMT1000 and the display was inoperable out of the box. Waiting for a replacement from the local dealer. Was thinking about upgrading all my units to the SMT series, but will have to reevaluate.
