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!

YellowTop-S 5,5L 
£ 319.00 Total, includes delivery mainland UK (Not Northern Scotland)

Optima Yellow Top 5.5 L is the first larger spiral wound lead/acid battery on the market to combine deep cycling with high cranking amperage.
It is suitable for forestry, building and construction equipment and for mid-size distribution trucks and special vehicles with electrically-powered accessory equipment.

Yellow Top U-4,2L (dual terminals - electrically similar to S variant below)

£ 259.00 Total, includes delivery mainland UK (Not northern Scotland)

OPTIMA YellowTop U 4,2L provides power for special vehicles with winches, engine heaters, large audio
systems, and other energy demanding applications that requires a battery with extra high capacity. The OPTIMA Yellow Top U 4,2L handles all of the above throughout the entire discharge cycle. It has the capacity to maintain high voltage during discharge, allowing you to utilize all of the stored current to a much greater degree than in traditional batteries. This, in combination with its low internal resistance, can also improve the sound of your car stereo. The U-model comes with additional GM-side terminals.

YellowTop S-4,2L
£ 249.00 Total, includes delivery mainland UK (Not northern Scotland)

OPTIMA YellowTop 4,2L provides power for special vehicles with winches, engine heaters, large audio
systems, and other energy demanding applications that requires a battery with extra high capacity. The OPTIMA Yellow Top 4,2L handles all of the above throughout the entire discharge cycle. It has the capacity to maintain high voltage during discharge, allowing you to utilize all of the stored current to a much greater degree than in traditional batteries.

To KEEP your new batteries fully charged and in top shape!

Solar Battery Charger! Around £20.00 - Everyone would benefit from one of these! So I have 2!!! You can just leave them sat on the parcel shelf/dashboard and plugged into the Cigarette lighter socket permanently... And I don't sell these (yet!)

(Dealers? Please contact me!)

12V Solar Battery Charger works to keep your car battery fully charged!  The charger converts solar energy to 12 volt DC current, to compensate for small steady battery drains caused by clocks, lights, radios, and other accessories. No installation necessary, simply plug the Solar Battery Charger into your vehicle's cigarette lighter socket and mount on the dashboard. Great for cars, trucks, SUVs, boats, RVs and more! Note: The Solar Battery Charger is not intended to recharge a battery that has been completely discharged. One of these Sun powered battery maintainers plugged into your cigarette lighter will help stop your battery getting discharged if you don't use your vehicle regularly! Available from lots of places on line or from electronics stores like "Maplins" etc...
