96FZJ80 battery running at 430cc...need to replace? I got an oil change at Jiffy Lube and they sure try to upsell all their services (diff fluid changes, coolant change, transmission fluid change, air filter, wiper blades, suv high mileage oil, battery, etc.). Anyways, they tested my battery and said that it's running at 430cc amps, but it's rated at 640cc amps. I can see some white corrosion on top and the battery is over 5 years old. So, I'm thinking of replacing it and I went to sears and looked at the Sears DieHard Marine Platinum 34M P2 and the Sears DieHard Automotive Platinum 34 P1. These batteries looks similar, have the same 880cc amps, 135 minutes of reserve capacity, cost the same $189.99, require a core exchange, and are probably made by Odyssey. The only difference is the color and the warranty. The automotive is gray and has a 4-Year Free Replacement and a 100-Month Prorated Limited Warranty. The platinum is blue and has a 3-Year Free Replacement Limited Warranty. Anyone know for sure if both are made by Odyssey? If these are the same battery, but the warranty reflects the expected use (boat vs car), then it looks like the car one is better for me. Any thoughts? Edit: I just went on consumerreports.org and the Sears Platinum Automotive 34 is rated the highest of all car batteries with a score of 91. The next 34s were rated 76, 75, 72, etc. The Sears Platinum Automotive 34 is rated best in life, reserve capacity, and cca. Oh yeah, the one rated a 76 is the Optima RedTop and it's biggest drawback is the reserve capacity gets an average mark with best on life and cca.
