Review title: Apparently "U" does not mean "Uninterruptible"
Product review: Once the batteries get old, or run low, this "UPS" will drop power to the connected equipment without warning. Apparently it tests the batteries by switching the actual load over to the batteries, instead of running an internal test and alerting you when the batteries are low. I contacted Tripp Lite support about this issue, and they claimed that this is standard behavior. Obviously someone at Tripp Lite has failed to grasp the basic concept of an "uninterruptible" power supply. If you want an actual UPS, buy something else.
