Car Battery issues and choices
At Cromwell Garage Ltd, we understand the essential role that car batteries play in the smooth operation of your vehicle. Modern car systems run numerous safety critical systems that are reliant on minimum voltages. If the voltage drops too low while starting the vehicle, it can trigger management warning lights from these sysytems causing them to be temporarily suspended. This guide will help you explore various car battery types such as lead-acid, absorbed glass mat (AGM), and enhanced flooded battery (EFB) to help you make more informed decisions as to when intervention is required.
Lead-Acid Batteries
The Traditional Choice
Lead-acid batteries are the most commonly used batteries in vehicles, renowned for their affordability and reliability. These batteries consist of lead dioxide and sponge lead, submerged in an electrolyte solution of sulphuric acid. They are durable and their lifespan is relatively longer compared to more advanced technologies, typically ranging from to 5 to 7 years.
Absorbed Glass Mat (AGM) Batteries
The Performance Upgrade
AGM batteries are designed with a special glass mat that absorbs the electrolyte, allowing for a spill-proof design. They exhibit enhanced performance, especially in high-drain applications such as start-stop vehicles and vehicles equipped with numerous electronic devices. AGM batteries generally have a shorter lifespan of 4 to 5 years but have faster recharging capabilities, making them an excellent choice for demanding driving conditions.
Enhanced Flooded Batteries (EFB)
The Ideal Compromise
Enhanced Flooded Batteries (EFB) offer an intermediate option between traditional lead-acid and AGM batteries. Designed to perform better under regular cycling, EFBs are a popular choice for vehicles that are frequently used for short trips. These batteries provide improved performance in terms of cycling ability and are generally more affordable than AGM alternatives, with a lifespan of around 3 to 5 years.
Choosing the Right Battery
Consider Your Needs
Modern batteries are maintenance free and only need a periodic check on the terminals to check for corrosion and security. Driving style influences how long batterys last. Too many short journeys will significantly reduce a batterys health. When selecting a battery, always replace like with like as although some batteries are more expensive their battery management systems are also configured so cannot be down graded due to cost.
