By far the best plan is to buy a charger designed for your battery.

MAXIM has lots of battery charger ICs and app notes.

Assuming (at that capacity) that it is a sealed lead acid, I personally favour
the Unitrode/TI UC3906 controller chip. Download the app note for this chip and
you will learn quite a lot about the care and feeding of SLA's. There are also
kits for chargers using this controller.

Might be cheaper just to buy a jump-start battery. Sears has 'em on
sale for about $40 in the automotive section. About 10 Amp-hours IIRC.
You get a built-in battery charger that stops charging when the
battery's fully charged, a DC-out plug, and, as an added bonus, two
monster clips just in case your car battery needs a jump.

Good luck!
