摘要：典型的锂离子纽扣电池规格已在系统电源的情况下提供了10年的电池寿命。最终用户应该评估中的具体应用的预期寿命，特别是对那些超过典型的商业环境，需要持续10年以上。这篇文章给读者的主要因素，影响一生的IC系统电源或备用电源锂电池，可供电的概述。Maxim > Design support > App notes > Battery Management > APP 1793 Keywords: lithium, battery, rtc, real-time clock Dec 03, 2002 APPLICATION NOTE 1793 Lithium Coin-Cell Batteries: Predicting An Application Lifetime Abstract: The typical specification for lithium coin-cell batteries has been to provide a 10-year battery lifetime in the absence of system power. End users should evaluate the anticipated lifetime in their specific application, especially for those that exceed typical commercial environments or that need to last more than 10 years. This article gives the reader an overview of the major factors affecting the lifetime of an IC that can be powered by either ……
