The battery is 12 volt 9 ampere. I bought it from Kushtia to use in a UPS. But while installing it in my UPS, I connected black instead of red. My UPS got damaged and burned right then. Now what will I do with the battery, so I am selling it. If anyone wants to take it, contact quickly. The battery is completely new, I didn't even get the chance to use it before the UPS broke down. Therefore, if anyone wants to take it, you can come, see, test and take it.
