Keeping the bad battery is your worst option. Finding a battery with a middle bad cell howlers a manufacturing flaw for that battery
Any problems from charging (over or under-charging) usually show up with more water loss from the battery-bank cell closest to the cable connection at the "pos" or "neg" terminals.
I use Trojan T105's, and just replaced with another pair after 10 years on the first. I would think that due to the fact your still have 3 good batteries only eighteen months old, that purchasing one similar battery would be the best gamble.
I would place the battery first in line in series with the best looking other 6-volt, and leave the other set in parallel. Since more batteries are likely under-charged now-day's than overcharged by old single-stage chargers, being first rather than last may help.
I would complain and return battery where purchased (if possible) since it looks to me like a manufacturing defect than poor "TLC". You might get a break even though slightly past warranty.
