I'd go for a caravan or leisure battery, they should last fine and have enough power to run a track for 8 hours and can be recharged over night.
They are safer than most car batteries being gel filled and are designed to power low loads for a long time.
A slot track doesnt use that much power in real terms and we used to run a 6 lane track at the club using an old car battery and it held out pretty well.
