you can check your own battery and alternator with the proper tools ( multi-meter) simply place the lead off the multimeter onto ur batter leads wit the car shut off and the output should be at or about 12.6v then once thas takin care of turn the car on and do the same thing the output now should read 13+volts which will let you know your alternator is pushing out enough voltage to keep your battery charged...

ive been told that i shouldnt use optima bc cobalt needs a special battery due to trunk placement, that the optima can overheat and blow??

i was wondering about the optima battery too... if anything place the battery up top in the trunk in a custom enclosure so u can keep the trunk finesse lol...you can always extend the terminal wires im sure....

Yeah I have had an optima red top and yellow top (not at the same time) mounted in the stock location. I was very disappointed in the red top as my headlights still dimmed bad running my 2 12" pioneer premiers with a lightning audio 1000w RMS amp.

I'll check next time my trunk is empty, some time this weekend, and let you know which one it is. I havnt seen a HO alternator that fits our cars but there is a couple how-to articles on fitting an extra alternator if you want to go that route.
