The Optima Battery is available in three different levels; YellowTop which is almost the only true dual-purpose automotive battery available for modern accessory-loaded vehicles, RedTop with the strongest 5-second starting burst for all vehicles that need a leak-proof starting-only battery and BlueTop for boats or RVs. All three Optima Batteries include features such as two to three times longer life than traditional lead acid batteries, more than 15 times the vibration resistance as traditional lead acid batteries, absolutely spill-proof and can be mounted in almost any position, maintenance free and with faster recharging abilities, as well as superior starting power no matter what the temperature. With a 24 or 36-month free replacement warranty, you can trust Optima's experience and quality for a high quality Battery that will perform reliably for the long term.
