Before we put our 2 group 27 batteries to bed for the winter we fill the cells with distilled water as needed. Then they get hooked up to a multi stage charger and they spend the winter being trickle charged. Check wet cells again before re-commissioning.
We did have to get new batteries this year but the oldest was 6 or 7 years old. I'd prefer if they would last 10 years but I gather that anything over 5 years is considered decent longevity for wet cells.
