My hope is that they had no plan to take care of the old one and that with a plan this one will last.

I am banking on the fact that it is propane, but I am also not a master mechanic by any means. I figure if it turns over and I get spark there is hope.

Finally, long term storage procedures are tempting but I fear that they won't do it and if they do they will forget how it works and not maintain the battery.
