Hey guys! Three years ago I was a victim of a hit and run. Not even two weeks after this incident, a couch flew out of a truck and hit my car while I was traveling down the highway (was unable to swerve out of the way due to being surrounded by semis). Unfortunately, my CL has been hibernating in the third car stall since these incidents. I have all the parts bought, just need to get them installed. When I tried starting her up for the season, she wouldn't turn over. First thing I tested to troubleshoot the problem was my batteries. Come to find out, all three of my OPTIMA YELLOWTOP batteries won't hold a charge anymore In retrospect, I should have hooked-up a battery conditioner/maintainer.

The reason I had three batteries was to support my audio system (total of 2,440 max RMS watts and 7,320 peak watts) and accessories (LED undercar kit, LED interior kit, etc.). Instead of buying three batteries again, I thought I would replace my stock alternator with a higher output alternator allowing me to buy only one or two batteries. I thought this would be a good route to go, especially since my stock alternator is getting old and has endured over 200,000 miles. What is the highest output alternator available for the 2G CL? The highest output alternator I have found is DC Power Engineering's 320 amp HP series [https://www.dcpowerinc.com/fit/2001~...69-320-hp.html]. Correct me if I'm wrong, but I believe the stock alternator for a 2001 CL-P is 105 amps. Does anyone have any experience and/or input on this alternator?

What performance battery manufacturer would you recommend? I heard since OPTIMA moved their production facility from here in the U.S. to Mexico, their quality has gone downhill. Thus, I am considering going with a different manufacturer like Kinetik [http://www.kinetikaudio.com/2009/products.asp]. Does anyone have any experience and/or input on Kinetik power cells? Thanks in advance for your help!

 

I've been using the Odyssey PC1200. Pretty pricey ($250) but pretty good for me too. Tons of cranking power and it's held up pretty well to me only using the car sparingly a couple times a month. Battery is relocated to the trunk and I have two amps, a capacitor and a 10" sub.

That's not all that much wattage. I use to run more than double that back in the day (when I thought it was cool to have loud bass) with just a couple caps.

If you really think you need a beefed up alternator, best bet is finding a good shop that will build one up for you.

 

Thanks for the input guys! After doing further research, I am leaning more towards sticking with my stock alternator and purchasing two powerful XS Power D Series batteries [http://4xspower.com/shop/product-category/12v-agm/]. I would place them in my trunk battery compartments (located on both sides of the trunk behind the plexiglass in the picture) and eliminate having a battery in the engine bay.



Does anyone have any experience and/or input with XS Power batteries?

 

or use the 130amp oddesy alt 31100-RJA-A02

 

Thank you YeuEmMaiMai. I know what I'm doing soon.
