I brought a microtek UPS years ago, and within a month the backup of the product becamed worst. I called the service centre and on checking defects the replaced my battery with a new one,
But again after 2 years, the backup became worst just it gave 15 mins backup after full charge and supply electricity to only two fans and CFL bulbs .
The product was not good and my money was wasted after buying it worst experience ever from microtek product.
