6.4.4 Notes during charging
 Charge current at the end of charge is over 0.05 C10A, which may result in permanent damage on
battery appearance and battery life; pay more attention to charging voltage.
 The used charger should have digressive automatic constant voltage device, please contact us if
use other kind of charger.
 If the ambient temperature is not 25°C, temperature compensation should be applied on the
voltage,
 using the formula is U=U25°C - K×(T -25)
 T—ambient temperature; K—temperature compensation coefficient
 Judgment on charge end point, usually, if the battery charge can meet any one of the below listed
condition, it can be regarded as the charge end point.
a)
Charged value is not less than 1.2 times of the released value.
b) The current is less than 0.005C10A (C10 = rated capacity of the battery) during the final
period of charging.
c)
The current is steady for 5 hours during the final period of charging.
