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 just thought that I have a small 12V 1.25Amp Battery Tender Plus charger I used to keep my motorcycle battery topped up during the heat of Georgia summers when I didn't ride much.  I could just hook it up when I wasn't listening.  That obviates the need to lug the battery to my work shop and also makes a much smaller battery feasible. I am becoming enthusiastic about this.

Thanks for the responses.  I hadn't considered that a fully charged 12V battery can provide 13.5 volts.  Perhaps a bit more research is needed.  I sure wouldn't want to mess up my first new turntable since I bought my VPI HW19 thirty or so years ago.Does anyone have opinions about TeddyPardo linear power supplies? That is another possibility

" I assume you are not married? " 
I was married up until July first of this year when Mary, my wife of fifty-one years, passed away.  Even before that I could get away with many things other audiophiles can't because my wife was a true audiophile and reproduced music lover herself.  At her funeral a long time friend (40 years +) who has been a audio professional all his adult life commented about how unusual Mary was that she understood the technical terms of sound reproduction and could intelligently discuss them.   When I told Mary I wanted to add two eighteen cubic foot sub woofers (Bill Fitzmaurice designed 25 Hz quarter wave corner horns) to the system in our den she just said, "OK, but let's make sure they look good."  She spent hours helping my apply blonde Burmese Teak veneer to the Baltic birch cabinets.

Well......I almost feel that I got weak and wimped out, but after playing twenty-five or thirty LPs on the new Clearaudio Performance DC
Wood turntable with the Clearaudio Tracer tone arm and finding them to sound damned wonderful I decided to stick with a winner and go all Clearaudio.  A little while ago I ordered the Clearaudio 12V Smart battery power supply.  As I wrote on a previous thread on this forum the tt, tone arm and an Ortofon Cadenza bronze cartridge is a birthday gift to myself to celebrate my 72nd birthday, my first birthday without my Mary since 1967.  I didn't want to cheap out.
