OPT3478 Optima Red Top Battery

These Optima RedTop Starting 12 volt batteries, featuring Spiralcell technology, are designed for all of your starting needs. Compared to conventional batteries, RedTops deliver a higher level of power to the starter in the critical first 10 seconds of a vehicle's starting cycle. The Spiralcell design allows for the lowest internal resistance of any battery on the market: .0030 ohms for 12V and .0019 ohms for 6V. Vibration and jarring, whether from off-road use or major potholes, can kill a traditional battery. The tightly wound construction in Optima batteries minimizes the plate movement and subsequent damage caused by harsh conditions, extending battery life. These Optima RedTop batteries are leakproof, so they can be mounted anyplace inside a vehicle, in almost any position.
