2022年6月8日 · 锂离子电池的电压都是3.7V,有时候放电电压会下降,一般会从4.2V下降到3.0V左右,所以电池上标的电压不是稳定输出电压。 锂离子电池的标准电压就是3.7V左右,所以3.7V和3.8V没什么差别,就是3.8V充电可能更足一点。 锂离子电池使用过程中放电的平台电压是3.7v,而4.2v指的是充电满电时的电压。 常见的18650锂离子电池,电压都是标3.6v或者3.7v,充满电的时候是4.2v,这跟容量关系不大,18650电池从1200mah到4000mah,3.7V是指电池…

Why does this battery use 4.2 V when its nominal voltage is 3.7 V?
2024年6月3日 · I changed my headphone power circuit and I noticed it was using 4.2 V to charge a 3.7 V battery. I am confused why it is using 4.2 V. I know to charge a battery you need more voltage than its rating, so you can supply energy to separate electrons. How do we get the exact value of 4.2 V. Why not 4.3 V or 3.9 V, why exactly 4.2 V?

今天,银行下调存量房贷利率了!为啥有人4.2,有人4.3? - 知乎
按照规定,存量首套房贷款利率,广州的下调的下限是:LPR+0。 但这个LPR并不是指当下的LPR(即4.2%)。 因为,下调利率时,还与买家当时选择 “ 重定价日 ”有关,也就是“你合同上写的,每年更新房贷利率的日子”。 我打个比方,你原来是固定利率,然后合同上写的更改房贷利率的时间是每年的1月1日。 那么,还没有到第二年的1月1日之前,你的LPR基数,就是按照之前的,而不是现在的LPR(4.2%),所以也就有了差别。 而后面取消固定利率后,新的买房人,发放 …
