The looks alone generate plenty of buzz. But it's the patented SPIRALCELL® Technology in OPTIMA RedTop batteries that's truly worthy of praise. OPTIMA RedTop batteries are built to withstand the abuse Trucks, SUV's and 4x4's experience on and off-road. SPIRALCELL Technology immobilizes the internal components of the battery, enabling OPTIMA batteries to withstand incredible amounts of vibration.
Vehicles modified for better engine performance demand more from a battery. OPTIMA batteries withstand the high underhood temperatures associated with these Performance vehicles. The sealed cells make the battery spill-proof, even if you install it on its side! This prevents external gassing and leaking which can damage engine components and limit battery performance.
If your battery is used in vehicles that demand extra reliability and performance, or if you just take pride in getting the best performance out of your vehicle, OPTIMA RedTop batteries deliver the performance you demand.
OPTIMA RedTop Benefits
* Lasts up to 2 times longer than other batteries.
* More power in the initial 1, 3, 5, and 10 seconds of the starting process than comparably rated conventional lead acid batteries.
* Constant performance quality keeping your battery running at the same level even as it's being discharged.
* Ideal for seasonal use, fully charged, it can sit unused for up to 12 months at room temperature (or below) and still start a car.
* 15 times more resistant to vibration than other batteries.
* Nonspillable and can mount in almost any position.
With it's patented SPIRALCELL Technology, OPTIMA batteries offer 15 times the vibration resistance and up to twice the life of ordinary batteries.
The OPTIMA® is like no other battery found in today's market. OPTIMA's unique SPIRALCELL design offers the greatest technology in providing a strong and clean power source that far surpasses any of today's filled lead/acid batteries. With OPTIMA under your hood, you can count on a longer lasting battery.
The OPTIMA® battery is truly maintenance free. When charged properly you will not have to worry about leaking, corrosion, or gassing. Periodically inspect your battery terminal connections to ensure they are clean, snug, and protected from the elements.
Open circuit voltage (OCV) and storage: OCV: 34 / 34R / 34/78 / 6V / 34M / 75/35 >12.8 volts
(for a fully charged battery)
D34 / D34/78 / D6V / D34M >13.0 volts
(for a fully charged battery)
Because of the high purity lead grid in the OPTIMA battery, it has a self discharge rate much lower than conventional flat plate batteries. This means the OPTIMA can sit for longer periods retaining enough charge to start your vehicle. Depending on storage temperature, the OPTIMA can usually sit for 8 to 12 months and start most vehicles.
When possible, store your battery in a cool, dry location. Check the battery voltage every 6 months and charge if it falls below 12.6 volts.
Remember, newer vehicles with on-board electronics such as computers, clocks, etc., require battery power to retain system memory while the vehicle is parked. If the vehicle is to be stored for long periods you should use a maintenance charger to compensate for this drain. This charger should be voltage regulated between 13.2 - 13.8 volts, 1 amp maximum. On older vehicles, without electronics, disconnect the battery cables when the vehicle is not being used for extended periods.
