The capacity of 18650 lithium-ion batteries is generally between 1200mah and 3600mah. To prevent short circuits, the positive and negative poles of 18650 lithium-ion batteries are separated. So its short circuit may have been reduced to its limit. A protective plate can be installed to prevent overcharging and discharging of the battery, which can also extend the battery life. How to detect the consumption of 18650 lithium battery pack batteries?
1. If the battery voltage is lower than 2.7V, you can use a charger (4.2V) to charge the battery. After ten minutes, if the battery voltage rises, you can continue to charge until the charger prompts full charge, and then check the full charge voltage.
2. Battery loss indicates that the battery voltage does not rise and the capacity decreases. Directly measure with a voltmeter. If the voltage at both ends of the 18650 battery is lower than 2.7V or there is no voltage. Indicates that the battery or battery pack is damaged. The normal voltage is 3.0V~4.2V (usually 3.0V batteries will have a voltage cutoff, 4.2V batteries will have a full charge saturation, and some may have 4.35V).
3.如果测量18650锂电池组,电池没有电压,这个时候有两种情况,一种是电池原来是好,长期亏电存放导致,这种电池是有一定几率恢复,一般是用锂电池脉冲激活仪(锂电池充放电仪)来对电池短时间多次充电,有可能修复。
4.检查电池容量,设置万用表为测量每小时通过的电流量,将两个金属杆放置于电池正负极金属端。
