8. Memory Backup Circuit Design Suggestion
存储器备份电路设计建议
A primary lithium battery is not rechargeable, when used for memory backup in combination with another power
source; current may flow into the battery from the other source. A protection diode and resistor into the circuit is
needed to avoid battery charging or over discharging. Select a silicon diode or a diode with minimum leakage
current, and design the circuit so that the amount of charging due to leakage current will not exceed 2% of the
nominal battery capacity over the total period of use.
当用于与其他电源组合的存储器备份时，主锂电池不可再充电；电流可能从另一个电源流入电池。需要
在电路中使用保护二极管和电阻器以避免电池充电或过度放电。选择具有最小漏电流的硅二极管或二极
管，并设计电路，使漏电流引起的充电量不超过总使用时间内标称电池容量的 2％。
While used for memory backup, the following circuit shall be applied:
用于内存备份时，应使用以下电路：
9. Warranty 保质期
6 months warranty for sample battery after date of production. One year warranty for finished battery after the
date of production.
样品电池保质期为（出厂之日起）半年；产品电池保质期为（出厂之日起）1 年。
