Sealed Maintenance Free batteries are widely used where minimal maintenance and space requirements are the main considerations. There is no water loss during the charge- discharge cycle and the battery works on the oxygen recombination principle.

• SMF batteries do not need any maintenance or water topping.
• High CCA-RC
• SMF batteries are the safest of all batteries to use because they do not emit any toxic gases.
• A long battery life and perform well throughout its life.
