An Uninterruptible Power Supply (UPS) is an electrical device that provides backup power to critical equipment in the event of a power outage or other power-related issues.

APC Back-UPS CS 500 does not power up?

Hi All,

The above device wasn't holding a charge, so I swapped out the battery, and it appeared to be fine for about a week.

Next thing I know, the "power" and "battery" lights were both on, but VERY dim indeed.

The device has now totally gone off and is unresponsive. I verified that the replacement battery isn't faulty as well.

Can anyone offer any assistance with this please? Thanks!
