Development and application of the front terminal VRLA lead-acid telecom batteries for access network

The storage battery is very important for the quality and reliability of DC power supply system in the access network. The front terminal narrow telecom battery is the excellent selection to guarantee the safety and reliability of the system. In this text, the reasons of the failures of batteries in the access network are found by the post-mortem analyzation of the common 12 V UPS batteries which had failed to use for access network application, and some improvements in designing are proposed. We also present our opinions on selection and maintenance of batteries for access network.
