What is an AGM Battery?

AGM batteries are a unique variety of sealed lead acid batteries, and are the most common sealed lead acid battery by far. AGM stands for “absorbent glass mat”, and refers to the fiberglass mats that holds the electrolyte suspended between the lead electrode plates. Because the acid is not “free”, AGM batteries can operate at much lower temperatures and have a much lower internal resistance than standard SLA batteries. The very low internal resistance of an AGM battery allows the battery to be charged and discharged very quickly.

What is a Sealed Lead Acid (SLA) Battery?

Sealed lead acid batteries are the most common battery found in scooters and motorcycles. A sealed lead acid battery contains electrodes of lead and lead oxide suspended in sulfuric acid. As the lead and the sulfuric acid combine, there is a significant electrical discharge as a byproduct of the chemical reaction. This discharge in turn powers your scooter’s motor or electric ignition system. Sealed lead acid batteries have a low power-to-weight ratio compared to other commercially available batteries, which makes them ideal for high current applications such as mobility or recreational scooters.

What is the difference between a Deep Discharge (Deep Cycle) Battery and a Starting Battery?

Different construction materials and electrode plate composition gives the two battery types their unique properties. Deep discharge (deep cycle) batteries have thicker plates and are designed for long and slow discharge cycles; starting batteries have a thinner plate and are designed for quick bursts of high energy. In general, a deep cycle AGM battery is used in long range electrical applications, such as mobility scooter or power chairs, and a starting battery is used in electric ignition systems for gasoline powered street scooters.
