I'm another lead acid user. My house bank is 8 Interstate golf carts, about 1,000 ah at 12 volts, half usable. Like Tilt Rider above, I get good service life from LA, 6-8 years in my case. I see LA as cost-effective and I've resisted changing to high tech batteries primarily for that reason. Changing the cabling and battery boxes doesn't appeal to me much either.
