A 20 lb (or so) sealed lead acid battery and an inverter, at U Nebraska at Omaha around 2003-2004. I had imported a Sharp SL-C700 and it was very power hungry. Smart phones were barely a thing (blackberries) at the time.
I think I was vaguely aware of the possibility of some unexpected metal shorting the battery and getting hot enough to start fires, so I bought a green rubber bath mat (which I remember had little sucker feet on one side) and wrapped it around the battery.
I finished my undergrad in 2004 with no incidents.
