My advice, if your batt compartment will handle the dimensions, change to 12v batts. Skip the whole 6v headache thing. If you have to have 6v batts, then check the acid level every 6 months and clean the terminals at least once per year. Take the wires off the terminals, steel brush, reinstall and coat with petroleum jelly. 6v batts are especially susceptible to terminal oxidation due to their low voltage.
If you are losing water on new batts, 6v or 12v look at your charger as it may well be over charging. Check the dates on the batts when you buy them. Father in law bought 4 new interstates. 2 of the 6v units wouldn't keep a charge after 13 months, turns out they were 20 months old when he bought them new. They wouldn't replace or credit due to the age.
Never let 6v or 12v batts get below 55% charge rate, it will ruin them. That means, when they get to 11.6v charge them immediately! Buy a load meter at HF so you can check them yourself.
