Hey guys, so my battery is fully dead. Any suggestions on what type of battery I should replace it with? I have airrex digital suspension and a 10'' sub in the back. Was thinking a yellow or a red top, I read that the yellow top is better for sounds. Also, I have my amp and suspension wired to my battery, is there any precaution I should take when changing the battery? Is it just plug and play back on once I get the new battery mounted in or should I just be careful and take it to a shop and have them install the new battery for me? Any suggestions would be highly appreciated, thanks guys!!

Optima's are not as good as they use to be. There is a thread just revived about "Battery died and this is what i learned." I put in a Duralast gold battery from Autozone in mine, but with all your accessories, you should go with a Kinetic or the Bosch AGM from pepboys.

get the one from pep boys, forgot which one it is, but great reviews. don't go optima or OEM, both suck

don't reuse the battery cover, not needed.

Bosch AGM from Pep Boys! $133 after online discount

I installed mine this afternoon & love it so far. The car starts up so fast now!

^^^^Yes, my recommendation also. IMHO, AGM is the only way to go:

None of the shops had the Bosch AGM, from hawaii unfortunately so I got the superstart AGM, tech told me it was similar and supposedly really good? Can anyone confirm?

^^^^The CCA rating (Cold Cranking Amps) of the Super Start is 525. The Bosch is 710. So it appears that the Bosch is a stronger battery.

Ahh they have another one:

But, it's a Group 34. The ISF uses a Group 24. A group 34 will fit, but it's an inch lower than a Group 24. I assumed you got a Group 24.

i ordered the bosch, picking up today. i got a diehard for my GS350, but swapped it to my IS F b/c it came with an auto zone battery with CCA of 525, now the auto zone is dead.
