Abstract

Load, internal resistance, ambient temperature, and dis-charge cycle greatly influence of life health estimation for valve– regulated lead acid batteries, as load increases, it is directly proportional to the depth of discharge. Other operating conditions such as float voltage are strictly observed as the battery manufacturers already identified this threshold. Batteries deployed in good power grid with relatively few cycles during its life and in the event that a discharge occurs, the coup de fouet modeling technique where the dis-charge voltage versus reserve charge characteristic or the unified approach can be used to predict battery characteristics. The above – mention parameters are highly significant in determining useful life health estimation of valve-regulated lead-acid batteries. As revealed in this study, telecommunication and other allied stakeholders carefully understand the technology and ensure that basic requirements meet like consideration on air-conditioning system in the battery room, the load are monitored and not to exceed the recommended threshold as these aforementioned parameters are highly significant on the useful life health estimation of valve-regulated lead-acid batteries
