For motorcycle riders, the battery needs to do more than simply start the engine. It must cope with vibration, limited space, varying temperatures and periods of inactivity. AGM (Absorbent Glass Mat) batteries offer several advantages over conventional flooded lead-acid batteries, making them a popular choice for modern motorcycles.
One of the biggest benefits is improved vibration resistance. AGM batteries use glass-mat separators to hold the electrolyte in place, helping prevent movement and reducing the risk of damage from the constant vibration experienced by motorcycles. This can contribute to improved reliability and battery life.
AGM batteries are also sealed and maintenance-free. Unlike conventional flooded batteries, they don't require regular checking or topping up of electrolyte and are designed to be non-spillable when handled correctly. This makes them particularly useful in motorcycles where the battery may be installed in different positions or in locations that are difficult to access.
Another advantage is strong starting performance. AGM technology generally provides good cold-cranking performance and can deliver the high current required to start modern motorcycle engines, including those with higher-compression engines and electronic fuel injection.
AGM batteries also have lower self-discharge rates than many conventional flooded batteries. This makes them better suited to motorcycles that may spend extended periods in storage. However, maintaining the battery with a suitable motorcycle battery charger or maintainer during long periods of inactivity is still recommended.
A worthwhile upgrade for your motorcycle
While conventional lead-acid batteries remain a cost-effective option, AGM batteries provide a combination of reliability, vibration resistance, maintenance-free operation and starting performance that makes them an excellent choice for motorcycle applications.
For riders looking for a dependable battery with minimal maintenance, upgrading to AGM can be a worthwhile investment.
