How long will a 12 volt moped battery last with a cd player and speakers wired to it on average?

Posted: June 8th, 2010 | Author: admin | Filed under: Questions | Tags: , , , , , , , , | 4 Comments »

I am buying and audio wiring kit speakers and a cd player for under my seat when I go to parties on the beach and places like that. I was just curious to how long would a fully charged 12v moped battery last on average if anyone else has done this before or knows? Thankyou

    dude do not put that crap on your moped,

    mopeds are gay.

    putting a cd player on it will make it look way gay.

    Don’t waste your time with that setup.

    Get a mp3 player & hook your speakers to that. Should get 8-10 hours of
    music play with that. If not, bring extra batteries for the mp3 player or
    a charger.

    Your battery will have an AH rating — that is amp-hours.

    Using at the beach you will likely be pushing a few watts of music, so your drain will be maybe 1.5-2 amps, call it 2. A 7AH battery, divide by 2 amps, equals 3.5 hours.

    Not long – a few hours at most.
    Watts = volts x amps.
    Add in some for losses.
