Message: <blockquote data-quote="Raisedin305" data-source="post: 1121617" data-attributes="member: 562370">When disconnecting a battery completely, the appropriate method is to disconnect negative, then disconnect positive. To reconnect, you should connect positive, then negative. This is for safety reasons to reduce the risk of spark while disconnecting and reconnecting the cables, which could cause the battery to explode.In order to disconnect the positive cable properly for safety reasons, you should disconnect the negative cable first, anyway. It's simpler just to remove the negative cable to disrupt the power flow than it would be to remove the negative, then the positive, so it's generally accepted practice to just remove the negative cable.</blockquote>
