I was planning to change inverter batteries for quite some time finally I bought luminous tubular batteries. Earlier I was using batteries from some local manufacturer. One of my friend recommended me to buy batteries from luminous because he recently purchased sine wave inverter and quite happy to share his experience with me. One of the key advantages of owning luminous product is the long battery life. I would also like to mention its 10-year life cycle, which is unique to Luminous. One of the common problems with inverter battery are leakage and corrosion but this battery provides excellent protection against the above mentioned evils. These batteries also perform well under extreme condition because I kept my inverter in my balcony. I bought these batteries for Rs, 7990, which justifies its price when we compare to its robust quality. In my opinion these batteries are perfect for my need and requirements .
