However, after finally reading the directions on use of battery tenders it appears that it is recommended to attach the negative clip (ground) to a part of the chassis instead instead of the negative post. I have never had any issues with attaching both clips to the battery posts. Does anyone know of any damage being done to the battery by dong so?
It has always been my understanding that what is recommended is a safety measure. That is, in case there is any leaky fumes around the battery, the point of spark would be away from the battery. And of course the negative should be the last connection made, for that reason.
