Not having the longer lasting battery life it's battery framing so fast I had using it for more than a year and the problem continues
And also not ease to use it's not as friendly in work as the others are Luminous inverter is not good for long life running but the battery is superb but the charger is quite bad.in my home we have two inverter bought for luminous and the warrenty period of charger 18 months given and the battery warrenty is given 24 m
