This battery type was created much later after the Red Top to keep up with the changing technology. The Optima Yellowtop Battery is the more evolved cousin of the Red Top.

This is because on days the vehicle is used, it will certainly experience instances of discharges higher than 3% – risking the sulfation and battery failure. On the other hand, this starting battery is not the best option for vehicles that are seldom driven. This explains why the Red Top battery is ideal for regular everyday cars fitted with alternators that ensure the battery stays charged when the engine is running. It releases lead surface crystals that form atop the battery, slowly killing it. After all, if its charge drops to more than 3% it starts to experience sulfation.

This type of battery is designed to maintain a nearly full charge. The Optima Redtop battery is categorized as an SLI battery, meaning it works in a starting, lighting, and ignition mechanism.

They also allow you to mount them however you want in your vehicle without affecting the recharging or starting performance. The batteries offer this impressive performance due to their sealed build. These AGM batteries (Absorbed Glass Mat) offer a maintenance-free and leak-proof performance with enhanced vibration resistance. Integrating a Spiralcell technology, the batteries feature immobilized plates that prevent the active paste inside them from loosening and shorting the plates inside. Both Red Top and Yellow Top Optima batteries are special for their superior deep cycle and starting design that improves their overall performance. In this case, we are looking at the Red Top and Yellow Top battery types used in cars and trucks, differentiated by their top cap colors. Optima Bluetop: Starting (with dark gray case) and deep cycle (light gray case).Optima Yellowtop: dual-purpose battery (starting and deep cycle battery).on the other hand, the casings are available in two colors, i.e. These batteries come in three cap colors,i.e Redtop, Yellowtop, and Bluetop batteries. The batteries can be primarily differentiated by the colors of their top caps and bottom casings. Optima brand offers a selection of excellent quality batteries.
