Batteries for all intents and purposes are a technical product, but this should not be a barrier to anyone’s understanding of battery technology and the purpose of batteries in a given application.
We realise that some companies like to make things ‘Tech-Heavy’, so that someone who is looking into their product range, with no prior experience, doesn’t have a clue what they are dealing with.
We are not one of those companies, we strive to Keep It Simple! With this in mind, we are cutting through the Jargon to help give you a better understanding of what batteries are and how they work! Here at Platinum we also provide a complete range of chargers for the batteries that we supply.
CCA stands for Cold Cranking Amps, which is relevant to the engine starting capability of the battery. CCA measures how well the battery will perform at certain temperatures. Platinum International uses the Society of Automobile Engineers or ‘SAE’ standard, which means the cranking performance of the battery is measured under controlled conditions at a temperature of -18˚C for 30 seconds.
For example, if a fully charged battery is rated at 590 amps SAE, it can produce 590 amps for a period of 30 seconds, at a temperature of -18°C. The voltage must drop below 1.2 volts per cell (7.2 volts for a 12 volt battery) during this test.
Ah stands for Ampere Hour, which is a measure of battery capacity or rather, how much energy can be stored in a battery. The higher the Ah rating, the more energy can be stored in the battery. The Ah rating is most relevant for slow drain applications, such as; Caravan & Leisure Vehicles; Marine; or other applications that take a large amount of energy from the battery over a prolonged period of time, these are also known as Deep Cycle applications.
Platinum International uses the ’C20’ or ‘20 hour’ standard for its automotive and leisure range. This means that a fully charged battery rated at 100 Ah (C20) can produce 5 amps (100 Ah divided by 20), for a period of 20 hours. Again this procedure is done under strict conditions at a temperature of +25°C, where the voltage must drop below 1.75 volts per cell (10.5 volts for a 12 volt battery).
A common misconception is that a 100Ah battery will produce 100 amps for 1 hour, 50 amps for 2 hours, 20 amps for 5 hours, 1 amp for 100 hours……etc. This is absolutely incorrect.
Depth Of Discharge (DOD), simply put, is how deeply the battery is discharged e.g. if the battery is 100% charged, the DOD is 0%. If however the battery is just 70% charged, the DOD is 30%.
A deeper discharge will have an effect on the service life of a battery, and for specification purposes it is important that the Depth of Discharge (DOD) is quoted. Platinum Deep Cycle batteries are rated at 50% DOD. A battery rated at 100Ah, which provides 120 cycles to 50% DOD means that 50Ah can be taken from the battery at least 120 times.
Yes. The battery on a conventional vehicle is solely designed to supply a high short burst of energy to start the car.
A caravan battery is required to supply a much lower current for a longer period of time, it will also be discharged and recharged many times.
This means that the technology and components differ from those of a standard starter battery, therefore use of a starter battery in a cyclic application would result in failure within the early months of service would be the result.
Yes. Again the battery on a conventional vehicle is designed to supply a high short burst of energy to start the car. Once the engine is running the vehicles charging system will replenish any energy taken from the battery and will supply all other electrical loads.
However, a Start-Stop battery is required to supply energy to the various electrical devices when the vehicle is stationary and the engine is not running.
This means that the technology and components differ from those of a standard starter battery, otherwise it would fail in the early months of service.
This depends upon the application. Vehicles at the premium end of the market tend to take Absorbed Glass Mat (AGM), whilst smaller entry level vehicles may take the Enhanced Cyclic Mat (ECM) battery. If the vehicle has brake regeneration, then the AGM battery must be used.
For battery replacement, an AGM must be replaced with AGM. ECM batteries must be replaced with an ECM battery, or you can sell up to an AGM battery.
ECM batteries are an evolution of the standard wet flooded battery. They have tin added to the plate grids and improved double layer separators, which provides longer life.
In addition to this the range has an increased reservoir of electrolyte acid, additional polyfleece scrim material on the plates & thicker plates which provide increased cyclic performance.
AGM technology utilises Absorbent Glass Material separators, which is a sponge like material that holds all of the acid solution. This makes the product 100% spill and leak proof as there is no ‘free flowing’ acid within the battery.
Also the negative plates have high carbon content, which allows for increased charge acceptance and a faster recharge, to work in line with brake energy regeneration.
A further distinguishing feature of the AGM battery range is the Gas Recombination technology. This keeps the Hydrogen and Oxygen within the battery throughout the charging cycle, therefore prolonging the life of the battery. A wet flooded battery may release some of these gases.
