Optima Yellow Top - Leisure

Demand More from Your Vehicle?
The YellowTop® high-performance AGM battery is one of the only true dual-purpose automotive batteries available. With premium cranking power and unparalleled cycling capability (rechargeability), it is perfect for modern accessory-loaded vehicles. The YellowTop can repeatedly bounce back from deep power drains to full energy capacity, so it can power plenty of electronics and still start you up time after time. Lower internal resistance also provides more consistent power output and faster recharges.
Trucks with winches, vehicles with multiple electronics, cars with high-demand audio systems, commercial vehicles and heavy equipment all rely on this battery to provide ultimate starting and deep cycle power.

Optima Blue Top - Marine

Endurance an Issue?
Installing an OPTIMA® BlueTop® high-performance AGM battery in your boat or RV means more running time and up to 3 times more recharges than what you’d get out of a traditional battery. It’s perfect for boats with electric trolling motors, onboard electronics or stereo systems and RV's with “creature comforts” that tend to drain batteries quickly. In addition to providing weight savings and outstanding vibration resistance, the BlueTop’s efficient power delivery and faster recharge time mean you’ll spend less time worrying about your battery. The OPTIMA BlueTop is ideal for those who need a sure-starting, strong cranking, maintenance-free power source.

I have been extremely impressed with the Optima batteries installed in my Defender 90. I am proud to continue handing out Optima literature and singing your praises! Optima batteries are THE BEST! Bill Burke | 4 Wheeling America
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
These are the batteries that we used on the Warn Glacier Expedition in Iceland. They performed beautifully and seemed completely unaffected by the cold. They worked for hours at a time as we winched the Jeep up and down Hvannadalshnjukur mountain and across Vatnajokull glacier. We also encountered very steep grades, but experienced no leakage with these starved electrolyte batteries. Barbara O'Donnell | Peak Communications
The Optima batteries have been quick-to-hit the juice in all circumstances. They crank our big fuel injected Chevy 350 without a miss. The "no maintenance" aspect and the durability of the Optima batteries has made a believer out of us. Larry Conville | Marketing & Promotions, Superlift
Putting an off-road vehicle through it's paces is awfully hard on batteries. Many is the time that I've seen normal batteries vibrated to the point that all of the electrlyte had been completely shaken out of the batteries. Result...very dead battery! With the Optima's Spiralcell Technology these are problems of the past! John Hale | Manager, Truck Magic
Your batteries are far and away the best on the market. We chose Optima because we trusted your product and haven't been disappointed. In good conscience, the only battery I could possibly recommend is the Optima to everyone, plain and simply THEY ARE THE BEST! Frank Schettini | Big Dummy Monster Trucks
