One of the users in a remote country tells me that their UPS (SmartUPS 700) is beeping once in every +/- 3 houres and there is red light burning that indicates that the battery should be replaced. The battery also indicates that it's fully recharged?
What seems strange is that it is fully recharged, why should it be replaced ?
Should the battery really be replaced and if so, is it easy enough to do for non-technical people to do it by themselves ?
Thanks in advace for your answers,
