Demand more from your vehicle? Then get more from your battery. OPTIMA YellowTop batteries are made for the extremes. If you have an extreme vehicle, you expect high performance. Whether your vehicle is made to take the abuse of off-road driving or cranking out decibels, you need more from your battery. OPTIMA batteries with patented SPIRALCELL® Technology deliver that performance. The deep cycle characteristic of this technology coupled with its extreme resistance to vibration provides performance vehicles with the repetitive power they need in a spill-proof package.
If your vehicle has a lot of accessories like running lights, high-performance stereo/AV system, winches, or hydraulics, your vehicle demands more from its battery. OPTIMA YellowTOP batteries provide the extra performance and deep cycling capability that your vehicle demands.
OPTIMA YellowTop is made to install and forget. No matter the conditions, be it dampness, heat, dirt or exposure to extremes in vibration or regular discharge, you can count on OPTIMA to deliver uninterrupted power. OPTIMA's ability to hold a higher voltage during the discharge cycle makes it possible to utilize more of the stored power in the OPTIMA compared to ordinary batteries. The YellowTop handles many discharges as well as re-charges without losing significant capacity. OPTIMA is also ideal for seasonal use because of its very low self-discharge rate. That means you can store your seasonal vehicles all winter without regular charging and still spring out of the starting block when winter is over.
OPTIMA YellowTop Benefits
- Dual Purpose starting and deep cycling.
- Lasts up to 2 times longer than other batteries.
- Constant performance quality keeping your battery running at the same level even as it's being discharged.
- More power in the initial 1, 3, 5, and 10 seconds of the starting process than comparably rated conventional lead acid batteries.
- 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.
Using OPTIMA SPIRALCELL Technology, cells are tightly compressed into supportive chambers, giving OPTIMA batteries over 15 times more vibration resistance than traditional batteries. This translates into longer battery life in high vibration situations.
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.
