Thats where I've seen em. Turbo Start 16v batteries.

Chris, I’m sorry to hear about the trouble you had with our 51R YellowTop. Generally speaking, the charging system on most vehicles is more than capable of maintaining the voltage of any of our batteries. What our customer service person may have been suggesting was that stock alternators are designed to maintain batteries, not recharge deeply-discharged batteries, which is correct.
Based on the limited description of your vehicle (daily driver, car stereo & alarm), it’s difficult for me to give a knowledgeable response about your specific application because of so many variables. If your vehicle is stock, a RedTop battery would work just fine. Your decision to choose a YellowTop, would suggest an application where deep-cycling was a frequent occurrence.
I don’t know if your alarm system is a factory unit or not, but many aftermarket alarms draw enough current to discharge any battery over a relatively-short period of time. I don’t know if your stereo is a stock unit or not, but even stock units can deeply discharge any battery, if they are operated at a high volume with the engine off (or in bumper to bumper traffic) for extended periods of time. Even your driving habits can be a factor. Daily driven cars that are driven on short commutes can gradually discharge any battery, if the alternator is not given enough time to replace the energy used to start the vehicle. This is a similar scenario to vehicles that are repeatedly jump-started, but the battery is never fully-recharged by the alternator or with a battery charger, leading to a cycle of jump-starts and “dead” batteries.
) and under moderate if not light conditions. I tried all of the tricks to get them back but neither one would take a charge once they died initially.
So yeah, I took them up on the offer.

thats crazy.its awesome it lasted as long as it did and still had perfect readings.i wish mine was that good.2 years and then trash.i had gotten mine online at 4 wheel parts and i guess now i know there was some kinda warrantee.but it seemed like it would be way more hastle then was worth to fight with them about it at that time.maybe it was parked for too long of time and couldve been saved.i did a 3 day trickle charge but it didnt hold.had to do something else.bought a excide battery and 6 years later still cranks and holds charge and i only started it once a month to let it charge and get the fluids moving.this summer finally gona be outa garage and somewhat restored.mine was a 03 model redtop i believe.when were the bad year optimas?Recieved this from the Senior Sales Application Engineer today:
Hi David
We received your battery today.
I took it out of the box and used a handheld conductance tester to check the cranking performance. Your battery, which was rated 650CCA when built April 28 1989, still tested 650CCA.
