<knock on wood> I have a battery bank in service for 6 years now that has had at least 6 but probably 12 run all the way to dead events or almost all the way to dead (snowstorms and our on-site generator didn't start and we had to snowmobile a generator and gas up to the site) the batteries still charge just fine and keep on running.
they are UB-4D sealed batteries. probably $2500 in batteries. so although we ran until pretty much dead (or completely dead in a couple events) we either had no outage or only a brief outage (1-2 hours) instead of a 12-36 hour outage.
