You don't need to add water to the ACDelco FreedomR battery installed in every new GM vehicle. But if a battery has filler caps, be sure the right amount of fluid is there.

Don't connect positive (+) to negative (-) or you will get a short that would damage the battery and maybe other parts, too. Also, don't connect negative (-) to negative (-).
