Red light on Battery Backup for servers?

I have a APC Smart-UPS 1500 battery backup rackmount battery backup for a few servers and there is a red light that has recently come on on the right side of the face of the battery.  I have two others and they seem fine.  This is the only one with this red light.  What does this mean?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This light means that your battery has reached the end of its life and needs to be replaced. You can find batteries directly from APC, with disposal included. Other vendors sell just the battery, as well.
