[QUOTE="hispls, post: 8827671, member: 614752"] No. Your factory head unit, if functioning correctly, will consume only a very tiny amount of power (to keep your radio presets and clock settings) when it is powered off. I've had to replace batteries on used cars more often than not very shortly after buying them. That said, it may well be worth having the alternator load tested. Dead or dying battery can put undue stress on your charging system and a malfunctioning alternator won't do your new battery any favors when you replace that. [/QUOTE]
