    If im looking at the battery in my car the positive needs to be on my right. Closest to the engine. Like in the picture. I guess im confused, is the batteries right side for positive my right side when I'm looking at it or my left side.

    This battery is very small and can be located in any position so you can put it in the tray with the terminal in any orientation you would like so that they connect to your battery cables.
