[QUOTE="audiolife, post: 1545949, member: 541383"] no more than likely with an optima (this is what happened to me) when its near dead or dead and you hook it up to a charger or jump start it the voltage shoots up really high on the charger at first and the inards cant take it so it malfunctions. what i always use is a power supply set up between 13.8-14.4 so it cant get a voltage spike. give it a good hour or 2 on the power supply (can charge all the way up from the power supply but if you leave it unattended a charger with autoshut off or a timer works good) [/QUOTE]
