Recharging of a maintenance free battery is neither required nor possible
A maintenance free battery has a relatively short shelf life when compared with standard batteries
A maintenance free battery requires little maintenance during normal use and it is sufficient to add water instead of an electrolyte containing sulphuric acid
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
Compensate for variations in the relative positions of the differential and the wheels which result from bumpy road surfaces or other similar driving conditions.
Absorb any difference in speed between the left and right wheels when the vehicle is turning
Absorb the vibrations transferred from the surface of the road
