- Deep cycling and cranking power all packed into one battery.
- Lasts up to 2 times longer than traditional flat-plate batteries.
- Constant performance quality, which keeps 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 vehicle.
- 15 times more resistant to vibration than traditional lead-acid batteries.
- Mountable in almost any position.
Like You, It Doesn't Know When to Quit
There's not another battery in the world that works as hard as the OPTIMA® battery. Especially against the number one enemy: vibration. The unique SPIRALCELL® Technology used in the construction of the OPTIMA® YellowTop S 5.5 battery makes it an excellent power source for demanding heavy duty engine starting and deep cycle applications.
Deep Cycle Batteries for Professional Use
OPTIMA® YellowTop batteries are guaranteed to deliver uninterrupted power throughout the entire discharge cycle. The ability to hold a higher voltage during the discharge cycle makes it possible to utilise more of the stored power in the OPTIMA®, compared to ordinary batteries. Plus, it's spill-proof, highly resistant to extremes of temperature and can be stored for long periods without maintenance.
OPTIMA®'s YellowTop last up to twice as long as traditional batteries, so if you rely on your vehicle to earn a living, you demand consistent high performance from all the parts you put into it. Unexpected downtime due to a battery failure can waste time and money and put you behind schedule. OPTIMA® YellowTop batteries are made to endure the extremes of commercial, heavy duty use and keep you moving.
NONSPILLABLE AND MAINTENANCE FREE OPTIMA® batteries are completely sealed and maintenance free, providing a solution for applications where flexibility in mounting is needed.
Optima batteries, incorporating patented SPIRALCELL® Technology, are still performing strong long after traditional batteries have died. Even after extended accessory use, you'll still have plenty of power to keep things going.
Where loud comes from
OPTIMA® YellowTop batteries, featuring SPIRALCELL® Technology, are designed for all of your deep cycle needs. It's perfect for people who are serious about sound. OPTIMA®'s power is cleaner with higher voltage output than conventional batteries enabling you to play your system louder and longer. They have a greater cycle life so they can be drained and recharged more often. Plus, they're spill-proof and can withstand 15 times the vibration of ordinary batteries.
New developments have created demanding electrical systems requiring a high performance deep-cycle automotive battery. OPTIMA® batteries can meet the needs of enthusiasts in the performance market. Our new YellowTop deep cycle YT 2.7 and YT 3.7 are ideally suited to meet your power needs.
Unparalleled Vibration Resistance
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 applications.
Due to its completely sealed case, the OPTIMA® battery is extremely safe and corrosion resistant. Acid can't leak or spill, making them clean, user-friendly and environmentally sound. In addition, the maintenance free sealed case design eliminates the need to add water or clean terminals.
Dual Purpose (Starting and Deep Cycle) Batteries for Professional Use
OPTIMA® YellowTop is designed to be fitted and forgotten! No matter the conditions, be it damp, heat, cold, dirt or exposure to extremes in vibration or regular discharge, you can count on OPTIMA® to deliver uninterrupted reliable power. OPTIMA®'s ability to hold a higher voltage during the discharge cycle makes it possible to utilise more of the stored power in the OPTIMA® compared to ordinary batteries. The YellowTop can endure many charge / discharge cycles without losing significant capacity. OPTIMA® batteries are also ideal for seasonal use because of its very low rate of self-discharge.
Thus allowing you to store your seasonal vehicles (classic car / boat) throughout the winter, without the need for regular charging and still spring out of the starting block when winter is over.
