Those things are made so cheap that it doesn't even pay to replace the batteries. Once they start having problems it's time to replace. Nobody, including the manufacturer, supports them. Used to spend time prying swollen gel-cells out only to find that the thing cooked them when charging. Decided a long time ago, if the UPS doesn't work tell the customer that they have to replace it. Don't waste your time.
