TPMS light flashes then solid - Dealer suggests new car battery

No, I do not run a cap. Your car battery is much stronger than any farad cap out there. I repair car-audio electronics and know for sure that caps have little to no affect. The are not a battery, therefore they do not provide reserve power. Their power is capacitative, however this burst/reserve is not meant to offset a chraging system or battery which cannot provide for the system adequately. Yes they act as a filter to ground, and sure they can help with some surge; but thats it. No ordinary person listens to music in burps of 1 second, which is about all that it takes to drain any cap with todays amps. A good battery or two, alternator, and "The Big 3" is better than any cap. Caps when used as desiibed in this thread are not a solution to a problem, and they are not a bandaid either - they are worse. They will not raise your charge or alternator voltage - which is the sole job of your alternator's rectifiers. In fact they will actually put more strain on your charging system. I dont care if its 1, 5, or 20 Farad; its not nearly as much as cold cranking Lead Acid reserve - even for my battery which has apparently seen better years. I'm sorry but Caps are such marketting voodoo. Now I'm sure I'll get some flamage but this is my honest opinion.

My stereo is 1400w clean, old school Soundstream Class A 10.0 and Soundstream MC140. They draw up to about 120A under their current woofer loads being 2x 8" subs running at 1/2 ohm, and a pair of door speakers. These amps are meant for purest detailed SQ but are also strong for some high listening S'Q'L. My MC140 gets hot enough to make your reflexes pull off of it - its working very hard to make great quality sound.

Back on subject: Its been two days since the trickle charge and still no TPMS light. I'm now 75% convinced I need a new car battery to completely satisfy the TPMS light issue.

I've been researching batterys, since I hear a lot of bad reviews on the Optimas from the past two years. Seems the best battery on my list now are ones made by Odyssey. A lot of off-road truckers, marine users, and it would appear any non-Optima junkied car audio enthusiasts like em. Odyssey makes Sears/DieHard Platinum series for $199. They have a 4 year replacement and a 10 year prorate. They are considered deep-cycle and made with Virgin-Lead plates. I can get one local, and in fact I even have a Sears coupon to make the price better.

Has anyone heard of Odyssey / DieHard-Platinum batteries?
