Some Information to Keep You in the Know
- Battery Types. Car batteries come in two main types, starting batteries (used for kick-starting a vehicle) and AGM (Absorbent Glass Mat) /gel batteries for car audio. The later are a higher quality, higher capacity deep cycle battery which uses up to 80% of their capacity (though they’re more expensive).
- Efficiency and Capacity. An efficient battery saves you time and money. Deep cycle batteries such as AGM, Gel and Flooded lead are the most efficient and boast the greatest capacity. The higher the C20 capacity the longer the battery will perform with the car off.
- Maintenance. The maintenance of a battery is directly correlated to how the battery is sealed. Flooded lead requires more maintenance whilst AGM/Gel requires the least.
- Mounting Flexibility. Flooded lead batteries are required to be maintained upright. AGM and Gel batteries which are 100% sealed can be placed in any orientation.
- Safety. Abused batteries may lead to a gas build-up and explosions. AGM and Gel batteries have a lower probability of exploding due to less usage of H20 to Hydrogen.
