SMF battery is totally maintenance free and has longer cyclic life, thus compensating the initial higher cost. One of the important aspects of battery life in relation to the use of equipment is the cut off voltage set in the equipment. If properly maintained, the sealed battery can give sufficient back up time. Let us see the tips to increase the life of UPS and Inverter battery.
