AGM battery quick facts

Are you looking for a reliable, durable, and long-lasting solution to keep your vehicle running smoothly?

AGM batteries are your ultimate driving companion, providing superior electrical performance and consistent starting power.

Don't let inconvenient setbacks disrupt your journey on the road. Whether you're heading to an important meeting, picking up the kids, or simply running errands, AGM batteries provide the peace of mind that comes with unwavering reliability and remarkable efficiency.

Discover what sets AGM batteries apart from other battery types as we share essential insights to get you acquainted with this high-performance solution.

AGM stands for "Absorbent Glass Mat"

AGM, which stands for "Absorbent Glass Mat," describes the unique internal battery design. Inside the battery, sulfuric acid is soaked up by special separators made of absorbent glass. These separators spread the acid evenly and keep it in constant contact with the battery grid. As a result, AGM batteries deliver reliable electrical output and excellent performance you can count on.

AGM batteries suit high-performance vehicles and advanced start-stop systems

AGM batteries are ideal for use in high-performance and advanced start-stop vehicles. Their fast charging and discharging capabilities and enhanced cyclic stability make them a reliable and efficient option for vehicles with these high electrical demands.

AGM batteries are designed to handle a high number of charge and discharge cycles

AGM batteries are engineered to withstand a high number of charge and discharge cycles. This means they can be drained and charged repeatedly without significant degradation in performance or capacity.

Such capability is crucial in applications where the battery undergoes frequent charging and discharging, such as in start-stop vehicles. The AGM technology and internal design of the battery enable it to efficiently handle these cycles, making it a reliable and long-lasting solution for demanding applications.

AGM batteries are sealed and maintenance-free

AGM batteries are designed with a sealed construction. Unlike traditional lead-acid batteries, AGM batteries are sealed during manufacturing and do not need periodic checks of the electrolyte levels. This sealing process helps prevent electrolyte leakage, making them safer and more convenient to use.

While AGM batteries are maintenance-free, they still benefit from some simple maintenance practices to optimise their lifespan and performance. For instance, keeping the battery terminals clean and free from corrosion and ensuring the battery is properly charged.

AGM batteries can only be replaced with another AGM

When it comes to replacing car batteries, AGM batteries follow a "like-for-like" replacement rule, meaning they should be replaced with another AGM battery.

Alternatively, if a vehicle is manufactured with an EFB battery, drivers have the option to opt for a "like-for-like" replacement with another EFB or upgrade to an AGM battery for a "like-for-better" replacement. Upgrading to an AGM battery brings several advantages, including increased fuel efficiency, improved electrical performance, and more reliable starting power, especially in extreme conditions.
