Flywheel, Colin's advice is perfect, have them load tested it is the only way to be sure.
If as I suspect they are duff then I can only say that they are very poor batteries.
Trickle charging them from time to time over an eighteen month period should not have trashed them.
Personally I use the Exide 80 amp hour batteries and they last me eight years on average.
Mind you I always keep a battery conditioner on them when the car is not in use.
Before I started using a conditioner they used to last between five and six years with no charging in the winter.
