“My son used our boat on Monday morning. When he left, somehow he forgot to turn off all my electronics. My units were on from Monday morning until Thursday evening. When I arrived on Thursday I noticed the electronics that had been on for four days. I figured that I was out of luck and my battery was drained below the point that I could not start my engine. Man, was I wrong! My engine started right up and I was able to fish that night. Caught some nice stripers too...

You kept me on the water and did not allow me to go home empty handed!” - Captain Bill Paciello

“I am writing to tell you how impressed I am with the Optima 800. I have been a car audio installer for over 15 years, and in my opinion these are the best batteries on the market for car audio applications.” - Tom Fasbinder, Owner | Fastronics

“I believe these batteries have evolved into a very good cold weather battery as our vehicles crank over well in temperature extremes down to -50°F. Also, no problems have occurred from summer heat. Since 1987, 50 of the original 65 are still in service.” - Bob Baker | Vehicle Shop Foreman, Winter Park Resort, Colorado

“We have been very pleased with our Optima 800 batteries. We are developing some very specialized high-end 4x4 off-road vehicles, comprise of US Military M1009 and M1010 trucks. By replacing the stock military batteries with Optima 800's, we were able to improve the electrical system of these trucks even further to build a near bullet proof starting and charging system. I would recommend Optima to anyone.” - Rod | American Off-Road Products
