Lead-acid batteries are the workhorse battery of standby power. Safe, reliable, and cheap, they dominate industries like telecom and utilities where backup batteries are essential in maintaining uninterrupted operations. Today, tens of millions of Valve-Regulated Lead-Acid (VRLA) batteries are in use at millions of sites across the country.Managing these batteries is not easy for the companies that buy them. Most of the time, the sites where these DC power systems are deployed are unmanned and remote. These deployment sites include remote broadband locations, railroad switching stations, or some other type of site where there is a durable cabinet housing industry equipment and the DC power system. In these cases, batteries are subjected to the elements: oppressive heat during the summer, cold during the winter, dust and humidity, animals, and more. The robustness of VRLAs to withstand these factors make them such a great choice in these applications, but the environmental pressures will affect reliability and battery life.
