[QUOTE="Silas Pradetto, post: 43536, member: 34"] Re: Lighting up a sign (project) Car batteries are designed for high-current, short-term (car starting) loads. You need a deep-cycle battery for a long low-current runtime, as Rob suggests. My diesel trucks have twin 1000 cranking-amp batteries, and they still go dead with the headlights on for an hour. I bet if you bought a string of white LED Christmas lights and strung them up in there on a small inverter you'd be fine. Alternatively, find a way to series/parallel a bunch of LEDs so the inverter isn't necessary (maybe cut up the Christmas light set?). Simply charge the battery in store during the day, put it outside at night. [/QUOTE]
