Hey guys, I spent 2 days on the phone tracking down a battery to replace the one on my 2005 G35 Coupe. The original battery is code 999M1-QB35C 550 CCA. Well, the only one I could find of a good brand was BOSCH S5 60D which seems to be 500 CCA. No other battery fits in that tight space. There is only ONE other that might fit which is some Optima 750 CCA.

Is it better for me to go with the BOSCH 500 or get Optima 750?

Can something bad happen to the car for using a lower power battery? (I don't care if battery lasts just 1 year or less as long as everything in the car is fine)

Here is the picture of the BOSCH

Thanks for input.

 

Bump please, I want to install the battery but not sure if I should return for the optima yellow top 750

 

Pretty much any 12v auto battery should work as long as you can secure it in place and the poles are in the right position (which they appear to be). The Bosch should be fine, just might not have the most cranking power. Don't make a habit of sitting in the driveway running the windows up and down and blasting the stereo without the engine running.

 

haha thanks. I barely even turn on the radio. Actually, I barely even use the car. I have 14k miles on a 2005. Just use it on Sundays to run on empty streets. If someone hits my car, he can't afford to fix it, and body shops here (3rd world country) are junk. Don't want to risk my car.

 

Uhm...Is central florida a third world country now?

 

Right? I'm confused

 

I'm moving to Daytona next year and I don't want to live somewhere with malaria and no hospital within 100 miles.
