battery may be dying, I don't know why else it would do that. I have no problems when starting up the car. I know the last time my
battery died on my acura it stalled a bit before finally turning on. What do you think could be the cause of the horn sounding funky? Do you think I should have my
battery tested? Thanks guys!!
yes if the voltage your
battery is putting out is low, then your horn/alarm/doorlocks/dome lights/blinkers are going to create an instant drain upon you pushing your remote. id keep an eye on it. if one day you start your car and you see AWD light light up and stay = your
battery is shot and has a few days to 2-3weeks left.
you gotta understand that it takes roughly 15-20mins to run above 2300rpm for the alternator to put back what was sucked away from starting the car. furthermore your
battery is used to "excite" the magnetic field in your alternator, creating a bigger drain on the
battery. if you do a bunch of short trips, especially at low RPM's = your not putting back what you took out, by the initial start-up.
nissan is screwing people by programming the car to drop RPM's so easily and quickly upon every acceleration from a stop. the alternator is having a hard time re-charging the
battery that way. plus dont forget, when you upgrade things (ie; radios/amps/etc) your taking a potentially 60-120watt radio out, and replacing it often with something that consumes twice the wattage - depleting your electrical system MORE than what you originally had. now couple that with phones/ipods/and a ton of other accessories and your gonna drain your
battery very quickly.
