ER14250 1/2AA 3.6V battery is a high energy lithium battery with a rated capacity of 900mAH, voltage of 3.6V, operating current of 50 continuous, 100 pulse, standard discharge of 0.5 mA and a cutoff. -Cut-off voltage of 2V.
If it is 14250M, it is high power type, with rated capacity 800mAH, voltage 3.6V, continuous working current 200, pulse of 400, a standard discharge of 2 mA. , and a cut-off voltage of 2V.
14250S is a high temperature type, with a rated capacity of 750mAH, voltage of 3.6V, continuous operating current of 50, 10 pulses, standard discharge of 2mA and voltage cut-off. of 14.5V.
The difference between 18650 lithium battery and ordinary 18650 lithium battery is as follows:
1. The capacity of lithium battery is different. The capacity of 18650 lithium battery is muchsmaller than that of ordinary 18650 lithium battery, which is less than 2000mah, about half as much.
2. The discharge current is different in size. The discharge current of 18650 lithium battery can reach about 20A, and the discharge current of ordinary 18650 lithium battery is about 1-3A.
3. The application scenarios are different. 18650 lithium batteries are mainly used in the production of new energy vehicle batteries. Ordinary 18650 lithium batteries are used in small digital devices and various power banks.
Detailed information:
The difference between the power of 18650 lithium battery and the capacity of 18650 lithium battery
1. The main features of 18650. Power lithium battery The material particles of the positive and negative electrodes are moresmall and have less energy density than ordinary 18650 lithium batteries. The separation materials and electrolytes used have better conductivity and conductivity.
2. The 18650 lithium battery contains more tab materials in the positive and negative electrodes than ordinary 18650 lithium battery (to reduce the internal resistance of the tabs and respond to higher current).
3. The 18650 battery supports high current discharge, which can reach a rate of 30C. Ordinary 18650 lithium battery only supports 1C discharge rate. (1C is equal to 1 times the capacity)
4. The capacity of 18650 battery is generally about 1/2 less than ordinary 18650 lithium battery if the capacity is 2000 mAh. is only 1000 mAh5. The maximum charging voltage of ordinary capacity 18650 lithium battery is 4.2V, and the voltage ofMaximum charge of power type 18650 lithium battery is about 3.65V.
The rated voltage of ordinary capacity 18650 lithium battery is 3.7V, and the rated voltage of the 18650 lithium battery power is 3.2V.
