JimZ HHR pm'd me about this issue a week ago and I still haven't found any battery that will fit the HHR and deliver the CCA or more, plus can be hooked to the vent tubes (which is a must).

 

Dont know if this will help just some food for thought I know that the optima bats are great but ha any body looked as the sears Die Hard they have a new Platinum lime out and is comparable to the optima I have always bought the Die Hard series batteries and have alway had great luck with them

 

Check out odyssey dry cells http://www.odysseybatteries.com/

 

I also have had a yellow top in every one of my cars and swear by them. Well, actually, I never think about them to be honest...(that's how good they are)

So is it a consensus that it's not safe to put one in the HHR? Even though it's a sealed batt?

 

Well I know this is a older thread but here is the answer direct from Johnson Control i.e Optima Battery:

As of now this is not an Optima battery for the HHR.
