A Novel Couple - But Faithful and Dependable

Abstract

Fiamm have introduced a new lead-acid battery for telecommunications duty which employs a hybrid construction, using low antimony-selenium spines for the tubular positive plates and lead calcium grids for the negative plates. The new battery features low self-discharge and good float charge characteristics. Very low water consumption combined with high electrical efficiency make the battery virtually maintenance-free. These claims are based on laboratory tests and extensive field trials carried out in collaboration with SIP (the Italian Telephone Operating Company), as reported in the paper, which also outlines the advantages of the new hybrid block-battery as a rechargeable power source for alternative energy schemes.
