About the Battery Buddy. I have this Battery Buddy in my DeLorean for the last year and a half. I haven't had any problems with this unit. This Battery Buddy has replace another battery saving device that operated in almost the same way that was sold by a DMC vendor where I have purchased some five years ago. This is way to go, beside using a main heavy duty battery cut-off switch. Kayo Ong #5508 Lic 9D NY [Non-text portions of this message have been removed]
