I'm more interested in picking up a really big one for a few hundred used. If it can't do a full 8 hour shift anymore but can only do 6 hours it's nearly useless to place that really uses it. But for my purposes an 80% capacity battery is still plenty good.
They might not deliver quite as happily to a residence as to a business as the battery would likely be located in a less-than-warehouse type location. But it's definitely worth a try!
You are correct that they require maintenance. Thankfully that involves topping off water levels periodically. http://www.giantbatteryco.com/gbweb/ProperBatteryCare.html
