Luminous Inverlast Tubular Battery: Batteries for long life.

I would like to share my experience of luminous inverlast battery. I had bought this battery in 2007. Now I have been using it for almost two years. It is a very user friendly and very low maintains equipment if we can care this properly it is giving very good services. First I want to tale about its Colure plastic box has being provided very good look for Luminous Tubular battery. It is an eco friendly battery. After using two years I have no problem with this battery. So I am very satisfied by this product. I am using this battery with luminous sine wave inverter that is also a very user friendly product. I can say It is justifying its costs. So I can recommend this product to other people also. I think luminous is not a bad company in service also because when ever I called their people they had come very promptly and now they are starting there toll free help line also. But I have some advice for luminous they should be more prompt on their servicing.
