Discharge at low rates gave up to 25% over actual capacity (42% above rated capacity). Excellent results for both charging and discharging, the lower temperature derating for cold weather installations compared to lead acid, low self-discharge properties, excellent resistance to electrical and mechanical abuse, absence of either memory effect or a minimum charge rate acceptance level make Nickel Cadmium Pocket Plate Batteries ideal for solar applications. Examples of typical commercial installations, some of which have been operating reliably for over twelve years, are presented and discussed.","PeriodicalId":177302,"journal":{"name":"INTELEC - 1979 International Telecommunications Energy Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122647860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lead acid batteries can easily be recharged, methods for the conservation of the charge are even very simple. The required capacity and number of cells in correspondence to the specified time can easily be calculated. The following requirements should be fulfilled: 1. Full capacity and stable voltage for an extreme long lifetime, 2. effective floating and a minimum loss of water, 3. no passivation effects under charge and discharge conditions, 4. insensibility at increased ambient temperatures, 5. no damage of the battery after a deep discharge, 6. uniformity of single cell voltage and individuel acid densities in all cells, 7. short circuit resistance, 8. maintenancefree for long intervals, 9. minimal requirements for installation and putting into service, 10. safety against explosions, 11. mechanical stability (transportation, installation), 12. indication of the state of charge and the state of aging.","PeriodicalId":177302,"journal":{"name":"INTELEC - 1979 International Telecommunications Energy Conference","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125729332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
