What is the reason why the lithium battery pack is not paired and cannot be charged?

Overview:The failure of the Lithium Manganese Dioxide battery for digital cameras to be charged is due to the imbalance of the voltage and internal resistance of each single cell, which exceeds the pairing standard.

The failure of the Lithium Manganese Dioxide battery for digital cameras to be charged is due to the imbalance of the voltage and internal resistance of each single cell, which exceeds the pairing standard. After the battery pack is used, the difference in capacity increases beyond the internal balance capability (usually 8 to 10 mA) that the charge control chip can provide. The single-cell voltage difference caused by charging cannot be effectively balanced and failed. The difference in terminal voltage of different capacity batteries will continue to accumulate and the chip will be locked. The battery pack is not charging properly.

such as:

There is a section that reaches 4.20v, the whole group stops charging, and the cycle is repeated several times. After the residual power is inconsistent, the battery with the best performance becomes the bottleneck, because the residual power is the most, and the one is flushed to 4.2v, and the other residual power is less. It may only be charged 1/3 of the capacity. The difference in the terminal voltage of different capacity batteries will continue to accumulate and the chip will be locked. The battery pack is not charging properly. If you want to learn more about 3.6V 2000mah Li-SOCl2 battery,you can contact us.
