Im sure this has been discussed here before but I have the hardest time searching specific posts.
…any way, my question is what kind/type battery is a good, readily available choice for 2011 2.2 LT HHR? Since I can be any where in the 48 states or Canada….I need a decent battery….that I can find replacement when needed also. I dont have any Idea how old mine is (bought car 2nd hand….battery in it…it charged up….been getting it done ever since)….but, after my recent shift solenoid swap and sitting few days it cranked without jumping….let it sit over night after couple short test drives…..next morning checked BAT voltage…12.3v….car still cranks fine but afraid its baiting me up to be stranded….lol

 

Original is group 90, group 47 is a direct bolt in. Group 48 and 34R have been used, but you lose the hold down clamp on the end. https://www.chevyhhr.net/forums/gene...ery-hhr-60294/

It needs the vent pipe. Some group 47 have it.

 

Walmart has best deal, & most batteries are made from only a couple sources. So Advance will charge more, because they do.

I got mine from Napa, Walmart was only a couple bucks more at that time..
