What is an AGM Battery?

The AGM or Absorbent Glass Mat battery is a new technology that has recently integrated into cars by manufacturers as a stop/start system that is helping to reduce environmental impacts on the modern world.

The stop/start system is growing rapidly with AGM batteries in constant demand. It has been created to reduce fuel consumption, CO2 emissions and contribute to a safer environment.

A stop/start system shuts off your vehicle while stationary and can be restarted once the driver puts pressure on the accelerator or clutch. By shutting the engine off after about 1.5 seconds and prolonging this until it is safe to drive off, this technology is designed to reduce fuel consumption and CO2 emissions by 5-10%. The AGM battery is cheap to manufacture compared to other strategies used to help reduce carbon emissions, making all vehicles more efficient and maintenance free.

The AGM car battery is becoming increasingly popular in new vehicles with car manufacturers such as Audi, BMW, Fiat and Volkswagen adopting the stop/start technology into their vehicles. The AGM battery is constructed so that it requires no ventilation and can be installed at any orientation.

There are several advantages of using a AGM battery that are more beneficial than the traditional style battery which are:

  • The stop/start battery helps to conserve fuel when at a standstill in awaiting traffic by turning off your engine helping to reduce fuel consumption.
  • The AGM battery has up to 50% more starting power than lead acid batteries, meeting the demands of larger vehicles and high powered engines.
  • Low maintenance and there is no risk of leaks or spills.
  • The stop/start battery has little risk of freezing and can operate in low temperatures making it easier to start your car in the winter months.

Vehicle manufacturers are increasingly demanding more AGM batteries to use in their new stop/start vehicles. The increase in the use of this new technology is working towards meeting the demands for EU legal requirements.

AGM batteries are a specialised meaning that when replaced need to be re-coded into your vehicle, therefore it is recommended that this is done by a professional only. This may seem like an inconvenience, however the pros out way the cons with cheaper running costs for consumers and environmental benefits that will help to reduce the impact caused on the environment. On average AGM batteries can cut C02 emissions by up to 8% more than your traditional battery. Stop/start technologies make driving easy.
