18650常见锂电池组合参数,18是直径18mm,65是高度65mm,0表示为圆柱形电池.
单节标称电压一般为:3.6V或3.7V
充电电压一般为:4.20V(钴酸锂为4.2V-4.3V)
*小放电终止电压一般为:2.75V,低于这个电压容易导致电池容量严重下降乃至报废
*充电终止电压:4.20V
直径:18±0.2mm
高度:65±2.0mm
容量:1000mAh以上,常规容量为2200mAh-3200mAh,目前18650电池容量做得*的是LG,能做到3600mAh,但价格也不低。
为防止电池短路现象,18650锂电池的正负极是分开的。所以它发生短路现象的可能已经降到了极致。可以加装保护板,避免电池过充过放,这样还能延长了电池的使用寿命。4.电压高:18650锂电池的电压一般都在3.6V、3.8V和4.2V,远高于镍镉和镍氢电池的1.2V电压。
