One older battery in a set will drag the others down.
Normally I'd blast you for that myth.. but in this case.. not so much.
The problem with replacing just one battery in a pair of 6V is best describe like this:
Would you buy a 12 volt battery where 3 of the cells were brand new and the other 3 were say 2 years old?
Well.. the O.P. Did just that.
Likewisde would you want say half Excide half East Penn battery
Or half 210 amp hour half 230
When you put two batteries in SERIES it is important they be same/same/same.. Basically twins of each other.
Now batteries in parallel you can mix and match no problem older/newer, bigger/smaller/ different brands for the most part does not matter so long as they are all the same type (Flooded wet, Maintenance Free, AGM)
But for batteries in series: Same/Same/Same
Each pair of 6 volt batteries becomes (Not magically) a single 12 volt when you hook up that jumper wire between them.
A battery is a collection of cells. They need not all be in the same case.
