My best guess is that your battery is toast. Lead-Acid batteries suffer from several damaging chemical processes if they are allowed to remain discharged for long periods of time. One of the real problems is something called "Sulfation". You can use Google to search out that term and also look at the many attempts to build de-sulfation devices.
