In this 2 part video I demonstrate how to revive deeply discharged optima battery’s that will no recharge in a conventional way. Plus show how to re-purpose …
Optima yellow batteries are a first class choice for your car,boat,caravan,motor home and many other applications.
Why should you choose an Optima Yellow Top Battery?
Optima batteries are of course a part of the giant Johnson Controls Empire. There is no doubt in my mind that these batteries are a top class, heavy duty product. The batteries come in three different top colours, blue, red, and yellow.
The red and the yellow tops are very similar types of batteries. The red battery is a starter battery and this is its primary mission. This battery has slightly more CCA (800 cold cranking amps) than the yellow top battery and will crank your engine over time and time again that is the batteries main job.
All the Optima batteries are AGM batteries and are completely sealed. That is one of the reasons that these batteries are used on all types of racing cars and are fitted to the interiors of many normal road cars; because they are sealed then they do not spill and can be used in the cabs of cars without any fear of acid spills should the car be involved in any accidents either on the road or on the racetrack.
The battery technology is also different to a normal lead acid battery, because of the shape of the batteries plates. The normal type battery has rectangular shapes lead plates but the Optima batteries use what they call “spiral” plates that make up each cell. They are made of individually wound cells that are made up of two pure lead plates, that have been coated with an exact amount of lead oxide, one plate is the positive plate and the other is a
The two plates are then separated with a very thin layer of glass fibre, (this is the glass matting part of an AGM battery). In the case of Optima this fibreglass is of a very fine texture. This fibre glass is what absorbs the electrolyte and also keeps the plates apart.
The parts are then coiled up, by a special piece of machinery which forms a complete spiral-cell, Optima; describe the finished cell as looking like a “jam roll” or an “arctic roll” perhaps. These calls are then placed into the special shaped casing that has to be a perfect fit. The casing can only be made from brand new polypropylene, because there may be some impurities in recycle materials.
Each battery is made up of 6 spiral-cells each with a value of 2.1 volts for a starter battery and 2.2 volts for a deep cycle battery.
The Optima yellow Top battery has everything you may need in a car battery and more
This battery is a true high performance battery and will cater for as much power as you may need for your car electrics. The yellow top can also be used for starting fork lift trucks and indeed tractors, such is the power that is produced by this product.
It is excellent for use with cars that are fitted out with many electronic gadgets, such as large stereo systems and in car DVD systems, The systems can be used without the car engine being switched on, because these batteries are very deep cycle they can totally discharge and recover when the car re-starts the engine and the alternator comes back into play.
Driver of 4×4 vehicle that carry winches on-board also find that the Optima yellow top will provide enough power to do the winching and then recover with charging. As I have said earlier this battery also functions very well as a forklift battery, tractor battery, or on many other applications.
The yellow top will on average work 3 times longer than a standard lead acid battery and because the cells are so tightly packed into the casing the battery will stand up to 15 more times the vibration of the said normal lead acid battery.
These batteries are totally sealed and maintenance free and can be fitted in any position on the vehicle. These batteries will give you the best starting power available. All in al the Optima product is top class, but the drawback is the price, they are at least double the price of other products, but price is not always everything.
