Chevy Corvette 2001-2003, RedTop™ Group 72/25 Starting Car Battery by Optima®. CCA: 720 Amps, MCA: 910 Amps, Voltage: 12.8 V, Resistance: 0.003 Ohms, Capacity: 44 Ah, Reserve Capacity: 90 Min, AGM Type. Enjoy the most powerful burst of cranking current for the fastest, most reliable engine starting possible. The spillproof, maintenance-free RedTop Optima battery is resistant to all of the most common causes of battery failure. While RedTop™ batteries are somewhat more tolerant of deep discharge than conventional flooded-cell batteries, they’re optimized for ordinary starter-motor service.
Designed to replace a conventional LSI (Light, Starting, Ignition) battery used in cars and trucks. Like all Optima batteries, the Absorbed-Glass-Mat Optima Spiralcell Technology uses pure, unalloyed lead electrodes for lower internal resistance, less outgassing and water consumption, better surface-to-weight ratio and improved vibration resistance. Pound for pound Optima performance is unmatched. You’ll never need to add water to an Optima battery, because it recombines hydrogen and oxygen inside the battery instead of venting them. The sulfuric acid electrolyte is absorbed into a fiberglass mat between the electrodes, so it can’t spill, even if the battery is mounted on its side, or cracks open.
Optima Batteries has been a subsidiary of Johnson Controls since 2000, although the patents for Optima’s style of AGM spiral-cell batteries have been around since the 1970’s. Johnson Controls is a major, world-class player in the vehicle battery, commercial HVAC, automotive seat, interior and electronics field. Optima Batteries are always manufactured in Optima-owned facilities to their demanding standards, and never relabeled or resold. Optima® offers ultimate professionals and enthusiasts all the power they can handle again and again.

This battery did everything I wanted. It powered my HDTV during tailgating for four hours and started the truck with no problem. Just what I was looking for.
Best batteries by far! I use lots of accessories and with a high output ALT this battery does the job. Lots of reserve power for the Optima Yellow Category. I recommend it as your next Battery.
Optima is the "optimum" in batteries. Since installing my new Optima battery I get faster starts, and with these cold northern Indiana mornings its nice not to worry about being stranded.
This is absolutely the best battery available. They don't leak. They are virtually corrosion free. Keep them properly charged and they are maintenance and trouble free. I have found they are very resistant to vibration and if properly mounted will out last any other battery in rough service such as boat racing and 4 wheeling.
Good battery. I like it because you don't have to add water to it, thus no battery corrosion on the terminals, don't have to worry about getting battery acid on you etc. This is the second Optima battery I have bought and no problems with that one either.
