if you have 2 batteries and 1 of them you know for sure is dead but haven't disconnected it yet. will it cause the other battery to not hold charge. i ask because i have a brand new interstate battery i use for starting battery. the second one is a old school lightning storm battery in the trunk. i know for sure the lightning storm battery is dead. i just never get around to replacing it. plus i have to find one that is the same size as well because of a custom installed.
thanks
