UPS not giving backup

bobnash251

Right off the assembly line
Hi all,

I replaced battery in my UPS in Oct 2011 . Untill last month it was giving me back up of atleast 10mins , sufficient to atleast shut down my PC. Now , my system just shuts down as soon as power goes off.But , my UPS starts screaming , going red.

Does that mean , it has charge but not enough to power my PC ? Could any one please advise ?

Regards,
