OPTIMA YellowTop™(Deep-Cycle) DUAL purpose -+ Starter Battery
OPTIMA YellowTop™ batteries are designed Primarily as DEEP-CYCLE batteries. They are truly DUAL use! This makes them ideal for engine starting too! Although the Red Top ones can give higher starting currents as they were primarily designed for this job. Anything that uses batteries in a cyclic manor, (like my electric wheelchair!) benefits from the use of these batteries. They will give longer life, better performance, lower internal resistance than conventional deep cycle batteries and Gel batteries. They offer faster charging, greater number of cycles, better performance than conventional batteries when partly discharged, greater temperature stability.
The very reason for this site, and the fact that I now sell these batteries, is because I used to have all kinds of problems with conventional Deep-Cycle batteries in my modified Power Chair! The stock batteries the manufacturers chose to use were extremely expensive, big and heavy “conventional style” Deep Cycle, sealed, GEL batteries 2 x 12v 56Ah.
They were thought to be the best solution available! They gave me 270 cycles of charge and discharge per set of batteries before they were buggered… That’s just 9 months! That means that I had 5 sets of them in 3 years because I used them every day… The price of the YellowTop Optima batteries is not much higher, but they can be Deep Cycled around 2 to 3 times more! That means in real terms 1/3 to 1/2 the cost! And less downtime. Also If you charge or discharge a normal deep cycle GEL type battery at high rates, then they form bubbles in the GEL between the plates, meaning less AMPS and higher internal resistance. This state of affairs never recovers because GEL is thick! Optima’s do NOT suffer this problem. In addition the OPTIMA’s can be charged faster, stored longer, discharge naturally at a lower rate, and most importantly they can deliver MUCH more current than a conventional Deep Cycle battery can. So much so, that unlike other conventional Deep Cycle batteries they can also be used for starting engines with hundreds of amps!
Some typical deep cycle, and Dual uses:
- Golf carts
- Electric wheelchairs
- Alarm systems, emergency lighting
- Backup power systems
- Orbiting satellite communication systems
- Emergency vehicles that use lots of electrical equipment and need to start engines
- Electric cars – EVs (Electric Vehicles) and multi fuel vehicles)
- Trains
- Buoys, standby generators
- Industrial cranes, diggers, and road maintenance equipment.
- Boats
- Caravans, Recreational Vehicles, camping power supplies
- Cars with powerful sound Systems fitted, or TVs.
- Anything in fact that needs a Deep-Cycle operation or/and a starter battery!
** If you ONLY need a starter battery, then the RedTop is better still as it can produce higher peak starting currents!
OPTIMA YellowTop ™
Optima YellowTop is made to install and forget. No matter the conditions, be it dampness, heat, dirt or exposure to extremes in vibration or discharge, it is guaranteed to deliver uninterrupted power throughout the entire discharge cycle. The ability to hold a high charge throughout the discharge cycle makes it possible to utilize more of the stored power in the OPTIMA, compared to ordinary batteries. All of these benefits are due to OPTIMA’s SpiralCell Technology®, which combines the advantages of a starting battery (High current capability) with those of a deep cycle battery (no damage due to repeated deep discharge cycles). It handles discharges as well as recharges without losing significant capacity and is ideal for seasonal use because it has a very low self discharge rate.

OPTIMA’s SpiralCell Technology has some real advantages over conventional batteries! A few of these are listed below, but for full details see the Technical pages.
- At least 1.5 – 2 times longer life than traditional batteries
- Optimal power for starting regardless of temperature
- Extreme vibration resistance
- Long Storage times without damage or discharge
- Non spill able – even upside down!
- Can be fitted and used in any position!
- Maintenance free
- More starting power in a smaller package than conventional batteries
- Less deterioration due to deep discharge than conventional batteries
- More “cycles” before aging than conventional batteries
- Can be used in extreme temperatures/buried for weather monitoring or surveillance purposes
- Faster charging is possible compared with conventional batteries!
For the cold, and hardworking vehicles that have got to start!
Where big engines and vibration can cause problems!
Where reliability counts and downtime is not an option…

Optima has taken the clean, reliable, high-power output that made the OPTIMA RedTop starting battery famous and engineered in DEEP-CYCLE capability. The The OPTIMA battery design uses the same elements that Optima used to make the Red Top Starting battery. Then Optima Battery engineers then increased the battery plate density. This design gives the OPTIMA YellowTop the ability to be deeply discharged and recharged without giving up the famous Optima Battery high starting ability.
- THE YELLOW TOP OPTIMA BATTERY provides high power output resulting in greater cranking ability at high current loads.
- THE YELLOW TOP OPTIMA BATTERY is fully recharged in as little as one hour.
- THE YELLOW TOP OPTIMA BATTERY has been verified in Life Cycle testing to exceed 350 complete discharges.
- THE YELLOW TOP OPTIMA BATTERY won’t spill, leak, or corrode. THE YELLOW TOP OPTIMA BATTERY can be mounted in any position – sideways, or even upside down.
- THE YELLOW TOP OPTIMA BATTERY lasts two to three times longer than conventional batteries. Optima Battery engineers have used high purity lead design provides a much longer shelf life, meaning THE YELLOW TOP OPTIMA BATTERY can sit unused for up to one year and still start your vehicle!
Will it fit my car/van/truck?
Optima’s were never designed to be “direct” replacements for a standard production vehicles battery. Whichever one you choose, be sure that it can be fitted! The responsibility for this is yours, and yours alone! – If you cannot fit it, it cannot be returned, because there can be no guarantee that it has not been used. Therefore it becomes un-saleable! You wouldn’t like to receive a battery that has been “used” would you!
They come only in the sizes and specifications above. This is because they have such low internal resistance even the small size 3.7L batteries can produce huge starting currents and they will start any normal car!
They were intended to be used in “special” vehicles with specific “difficult” battery needs. They will undoubtedly be a major improvement over your “normal” standard automotive battery, (as well as some of the Optima “pretenders!) but may need some minor adjustments or fabrication to the hold down clamps or terminals/cables etc to fit your vehicle. If you are unlucky, both! If you are lucky it will just fit right in!
It may happen that the terminals are the “wrong” way around for your car. This is pretty easy to solve simply by turning the battery around. Or it can be fitted on its side! If the terminals are not the correct type then “converters” that go from Round DIN style, to the square bolt on type are available from places such as Halfords in the high street.
Download the pdf files to check measurements etc. Be sure! If you are not sure then get an Auto electrician or a qualified person to advise you.
