If not, pitch it in the trash and buy a 2 or 3 amp charger/maintainer. By adding the electrolyte yourself the battery will have been dry from time of manufacture so no deterioration will have taken place. That means the manufacture date is immaterial so don't worry about it. Actually, what really matters is how long it has been since the initial charge. If the battery supplier just now charged it, and charged it correctly, you'll be OK.
