OPTIMA®
REDTOP® A STARTING BATTERY WITH PERFORMANCE POWER
The looks alone generate plenty of excitement. Made for tuner, truck, SUV, and 4X4 vehicles: OPTIMA® Batteries can withstand the high under-hood temperatures in vehicles with performance engines.
The sealed cells make the battery spill-proof, even if you install it on its side! There’s no chance of potential damage from battery acid. In addition, the patented Spiralcell® Technology in OPTIMA® Batteries immobilizes the internal components of the battery, enabling OPTIMA® Batteries to withstand incredible amounts of vibration.

YellowTop® batteries are made for the extremes. Whether your vehicle is designed to crank out the decibels or take the abuse of off-road driving, you need more from your battery. OPTIMA® Batteries with patented Spiralcell® Technology deliver deep cycle characteristics coupled with an extreme resistance to vibration. This combination provides performance vehicles with the repetitive power they need in a spill-proof package.
If your vehicle has a lot of accessories like high performance stereo/AV systems, extra lights, winches or hydraulics it demands more from its battery. OPTIMA® YellowTop® batteries provide the extra performance and cycling capability that your vehicle demands.
