I went to a local audio/video shop and they told me that there isn't a replacement battery that will fit in the cobalt because the battery is in the trunk and its too tight of a fit. I'm hoping that this information is incorrect because I really need a new battery and i was wondering if anyone else has had to replace their battery before with something that is higher performance like an optima yellow or any other deep cell battery. Thanks for your help!

I haven't had the "pleasure" of changing a battery yet...

 

For a CAR battery??

 

lol my optima battery is to tall so the carpet sits up on that one side

 

damn i was really hoping to find a deep cell that would fit! no one else has ever replaced their stock battery mounted in the trunk with a deep cell?!?!



and yes...they sell deep cell battery's designed to handle the excessive power of car stereos

 

same here. it pissses me off.

dude, no offense, but, that whole bumping every ten minutes is a tid bit annoying.... I believe that your question has been answered.... the only real "performance" battery you're gonna find is an optima, and people have chimed in (and now I am) where the optima raises the carpet a little...it's no big deal and won't affect the perofrmance of the battery whatsoever

 

my laptop was freezing up and it wouldnt send my post. not my fault man. and my question was not answered:

but thanks for your input...i was thinkin optima but now thats out of the question

 

would mounting it sideways help? it's a dry cell so you can, just don't know if there's room

 

thats a good possibility...i just dont want to do anything that hasn't already been tested and proven by another member. I wish someone has done something before!!

 

im running a optima yellow top, great battery, hasnt let me down yet, have had it for a little over a year now, also im sure it can be mounted sideways aswell, there is room for it

 

yea i definitely want the optima...thats my first choice but im worried about fitment issues...pictures would really help!
