I have this UPS: Powercom KIN-1000APRM, which uses 3 of these batteries: Kung Long WP8-6S 6V 8AH. This is a 1U UPS, so the replacements have to be an exact match in dimesions, as there is no room for anything bigger, and I don't want to lower the capacity. I am not able to locate these batteries anywhere! If you have a trusted source, please check if you can get these batteries. It's a great UPS, but I am starting to think that they were a bad investment :/
