In one embodiment of the present invention, the UPS (or a circuit included therein) estimates a remaining life (ERL) of the battery by considering various battery conditions, including, but not limited to, a predetermined battery life expectancy, whether the battery is being used to power a load, and battery temperature. If it is estimated that the ERL is low, or below a predetermined threshold, then the UPS (or a circuit included therein) is configured to notify a user that the battery needs to be replaced."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Estimated remaining life of a battery included in an uninterruptible power supply","description":"An uninterruptible power supply (“UPS”) is provided with a backup power supply that has an adjustable reserve power level that is based on a user's input and/or is configured to notify a user if a bat","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8471531","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
