There are two reasons why lithium batteries cannot be charged at low temperatures.
< br >
1, low temperature leads to the battery itself performance degradation affecting charging.
< br >
2, the equipment protection does not allow charging.

Under normal circumstances, the recommended standard charging time for lithium batteries is 15 hours, how is this calculated? As said before, the charging current is related to C, generally set to 0.1C charging current, so calculated, in theory should be 10 hours, but generally considering the problem of charging efficiency, the manufacturer recommends 1.5 times the charging capacity, so the standard time is 15 hours.
Yadi lithium battery can not be charged at low temperature, which may be a problem with the battery. You need to get it repaired at Artie's.
