![]() AGM batteries have fiberglass separators or glass mats that “absorb” the electrolyte solution inside the battery. Optima batteries feature an AGM or Absorbent Glass Mat design, a VRLA battery designed to support the higher electrical demands of modern cars and trucks. There are many types of car batteries, but there are two general classifications: Flooded battery (wet cell) and Valve Regulated Lead Acid or VRLA battery. Meanwhile, the signature Six-Pack spiral-wound design increases the plate surface area to deliver greater starting power. The spiral winding technique offers better vibration resistance and more efficient power output. Whereas conventional car batteries have flat and square lead plates, Optima batteries use a series of individual spiral-wound cells composed of two pure lead plates coated in lead oxide (these spiral cells look like a jelly roll). Optima batteries are available in three variants: RedTop, YellowTop, and BlueTop, and all share the same proprietary design. While YELLOWTOPS (other than D31T) only have SAE post terminals.On Our Partner’s Website What Are The Types of Optima Batteries? Overall dimensions (including terminals): 12-1/4"L x 6-7/8"W x 9-7/8"HĪll dark gray Optima batteries (regardless of the top color) are starting batteries,Īnd all light gray Optima batteries are starting/deep-cycle (dual purpose) batteries.Īlso Note: The difference between BLUETOP and YELLOWTOP dual-purpose batteries is that BLUETOP batteries have both automotive (SAE) post and threaded stud terminals,.Dual top posts: SAE automotive and 5/16"-18 UNC stainless steel threaded studs for lug-style battery cables. ![]() Unaffected by vibrations that destroy ordinary batteries.Never needs water sealed - so no corrosion can form on the posts, connectors, or cables.Spill proof - no excess liquid can be operated in any position without the risk of leakage.Can be used with high output alternators.95% charge efficiency 80% depth of discharge capability (compared to 50% for lead-acid).More economical than ordinary batteries over the long life of the battery.Longer service life – up to 3 times the cycle life of a traditional battery.Spiral design provides lower internal resistance for faster recharging and consistent power output.Higher, more consistent voltage under large loads.High power density and exceptional running time between charges.They are also ideal for trucks with winches, cars with high-demand audio systems, commercial vehicles, etc. They are ideal for powering heavy electrical loads including trolling motors, GPS, pumps, fish finders, winches, etc. The light gray/dual use models should be used in boats and RVs. Key benefits of Optima Bluetop batteries include high starting power (both starting and dual use versions), up to three times more recharges than any other marine battery (dual use models),ġ5 times more resistant to vibration, leak proofness, and they can be mounted in virtually any position without maintenance.īlueTop batteries feature both SAE automotive posts for starting applications, and 5/16" threaded studs for easy installation in your boat or RV. Versatile BlueTop Marine and RV batteries are ideal for those who need a power source that requires no maintenance, and provides a safe start with plenty of power to run accessories. They feature both automotive (SAE) and threaded posts, outstanding resistance to vibration, with high efficieny power generation and faster recharge times. Optima Bluetop Batteries are high performance AGM (Absorbent Glass Mat) batteries with exceptional runtime and more recharges than you would get from a traditional lead-acid battery. The dark gray case BLUETOP starting battery should be used when a dedicated starting battery is required it should never be used for cycling duty. The light gray case BLUETOP dual-purpose battery can be used for both starting and deep cycling it is a true deep-cycle battery with extremely high cranking power.
