Dc for power supply

Anyone use 12v or 24v car battery as dc power supply for home audio.   Or even for filament on tubes.   I like to know if any members try different types of battery. Lithium, Lead Acid, NiMH, Agm, Gel etc... Can you tell me if it makes a huge differences on each type of battery. I like to use it to run my dc filament on a cd player. Please advise??
