Bought a Eaton 5P550R 550VA/420W off of ebay. Seller indicated it was pulled because it needed new batteries. So it did not come with batteries.
But the main issue Im having is that it will not power on at all when plugged in. Ive done tried to hold down the power button for 5-60 seconds nothing will show up on the Display.
I don't want to buy the batteries if this doesn't work.
Anything else I should try before I toss the $130 appliance into the e-waste bin?
