I would not worry about the unmatched in age, and they are most likely DEEP CYCLE but.. Gel batteries are not really a good choice because as batteries go they are very very "Finikey" they do not like a fast charge. They do not like OVER charge. they are more than willing to die at the drop of an excuse.
AGM's have many (All in fact) of the benefits of GEL. but they are the LEAST finikey.. Both tend to be expensive.
That said. If you add them .. In parallel since they are 12 volt batteries, with your existin pair of GC-2's the best advice I can give you is this;
If you have a programabble charger DO NOT INCREASE the basttery capacity setting, Take the slower charge instead.
After all FREE is a darn good price.
