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 a 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
