For generic stuff on Sealed lead acid's try the yuasa website.
SLA's will typically be supplied ex factory with a part charge to protect them in storage. This will decay and the battery will be damaged if it's left sitting uncharged.
Battery life varies according to their design, storage conditions, and usage conditions - like cyclic or float applications.
I'd expect yours to be damaged just from the length of time they''ve been sat - Sorry !
One extra option for chargers: performance motorcycles these days use small gel batteries that easily run down if they're left to stand for a couple of weeks with a burglar alarm active. Smart chargers are specially made to deal with this problem and can can do battery diagnosis, charging at typically a couple of amps, and then maintain the battery not by constant float charging but by monitoring voltage and pushing in a 2 amp top up charge whenever the battery voltage falls below a target value. I've used one of these on a 12v / 17a/h pack recovered from a fire alarm system and it works fine.
Cheers,
