I always get several years(6-8) out of good heavy Group 1 6v..

Regular excitement(weekly if poissible) and using "distilled" water ONLY is all I do .

Note: when you buy a new battery look for the little colored sticker size of a dime on the case...It shows month/year...Do not buy it if is over a month old.
An also if dusty! HA!

New but stale batteries (sitting around to long) just don't seem to hold up as well as fresh new ones put into service relatively soon after manufacture and first charge.

Try to buy from a place with a high battery turn over ..For 6v it maybe
Marine or tractor dealers....Not your average auto parts store who carry one 6v for the occasional antique auto or V.W. buff.
