Ok, two things to try here, this is the FIRST and LAST options (different 
batteries tenders are all the steps in between.)

FIRST- bring it back to where you bought it, most likely there is a 
warrantee.  Most places (like Walmart and such) don't care (or know how 
to) test the battery and just give you a new one.

LAST thing to try, before buying a new battery.  WARNING-  if you are a 
eco-warrior, you may want to skip this! I know the thought of this may be 
re*volt*ing!  8>)

If the battery is not a sealed battery, dump all the battery acid out of 
the core.  Refill with normal water and rise it out a couple of times. 
Note, recover ALL the water as it is hazardous.

Once cleaned out, fill with battery acid and put on charger.  There is 
about a 50% chance of this restoring even a sulfated battery this way. 
Dispose of the waste water properly.
