I have a Tripp Lite BC Pro 1050 UPS that has an issue. The batteries in it were old and failing, so I replaced them. When I plug in the unit, I get a blinking yellow light next to the battery icon that has the line through it, along with the green AC light. I'm assuming this means insufficient charge on the batteries.
(I've been unable to locate a manual for it around here.) I've checked the batteries...they measure 19.82 volts. It passes AC when plugged in, but pull the plug and it dies with no lights. I've checked the fuses, they are good. Any ideas anyone? Thanks.
