A maintenance free battery requires little maintenance during normal use and it is sufficient to add water instead of an electrolyte containing sulphuric acid
A maintenance free battery has a relatively short shelf life when compared with standard batteries
Since it is sealed, the water in maintenance free battery is not lost through evaporation thus accordingly it is not necessary to top up the cells with water
Recharging of a maintenance free battery is neither required nor possible

Enhances safety by serving two independent lines in a divided line brake circuit
Enhances safety by activating the brakes using vacuum pressure in the event of brake fluid loss
Supplies equal fluid pressure to each line of a divided line brake circuit, thereby preventing the brakes from dragging on one side
Boosts the brake fluid pressure to reduce the force required to depress the brake pedal
