How do I know if it's the battery or the unit?
Hello,
Yesterday everything was fine and today I woke up with a powered off NAS and no lights on the Back-UPS 650. The NAS went off unexpectedly, no alarm or messages. The Back-UPS won't turn on at all. Pressing the reset on the back has no reaction. Before I go and buy a new battery I would like to know if the unit itself is working. How can I make sure?
