Possibly Dumb Question re:Battery as a power supply

I have bought a new Clearaudio Performance DC Wood turntable.  I plan to drive to the dealer in Atlanta and pick it up next Wednesday.  I have seen the wall wart power supply which comes with the TT, and it is not a pretty sight.  Clearaudio sells an upgraded 12V battery and charger supply for "only" $1,200.00.  I don't wish to present myself as a parsimonious individual,  but $1,200.00 seems a bit steep to me.  I am wondering what problems would ensue if I bought a moderately sized (say 25 or 30 lbs.) , sealed, lead acid, 12V rechargeable battery; attached the proper wires to connect to the TT, and used it as a power supply.  When the battery runs down I could just take it to my workshop and use my electronic, automatic battery charger I use to recharge car, truck and tractor batteries to bring it back to full power.  As little current as the TT uses this shouldn't be too frequent a chore.  It is just a possibility, but if it is feasible I might try it.  I would really appreciate any and all comments, criticism or warnings.

I don't see much likely benefit in powering a TT by battery.  After all, the TT just goes round and round.  Wow and flutter figures on current good TTs are vanishingly low.  I have seen no evidence that battery power lowers them further.

But powering amps by battery seems much more likely to pay dividends by abolishing at a stroke all the grunge coming in from the power company.

Any benefit of coloured fuses when using battery power would be an interesting topic for discussion by those who believe fuses can have an effect on a mains powered amp.
