An absorbent glass mat battery is also installed beneath the front left seat on some vehicles, depending on the equipment level. This type of battery has set electrolyte (which means it cannot leak), it has a fixed cycle and it is completely maintenance-free.
Absorbent glass mat batteries have greater resistance to weather conditions and are more resistant towards vibrations than conventional lead-acid batteries. In addition, absorbent glass mat batteries do not leak or become damaged if they are tilted or subjected to gravitational forces.
