Features

Product Features

01

LARGE CAPACITY: Typical capacities for 18650 lithium batteries range from 1800mAh to 2600mAh.
02

LONG SERVICE LIFE: Under normal use, the cycle life of the battery can exceed 500 times, which is more than twice that of standard batteries.
03

HIGH SAFETY PERFORMANCE: By separating the positive and negative terminals, the battery is effectively protected from potential short circuits.
04

NO MEMORY EFFECT: The battery does not have to be fully drained before recharging, which makes it more convenient to use.
05

SMALL INTERNAL RESISTANCE: The internal resistance of polymer batteries is lower than that of ordinary liquid batteries, and the internal resistance of domestic polymer batteries can be as low as 35mΩ.

4	Delivery voltage	3.80~3.9V		Within 10 days from Factory
5	Charge Voltage	4.2V±0.03V		By standard charge method
6	Standard charging method	To charge to 4.2V, a constant current of 0.2C and a constant voltage of 4.2V are applied. The charging process then continues until the current decreases to or below 0.01C.		The battery is charged at a constant current of 0.2 times capacity (C) while maintaining a constant voltage of 4.2V. The charging process continues until the current decreases to or below 0.01 times its capacity (C), which typically takes about 6 hours.

13	Storage temperature for a long time	-20~25℃60±25%R.H.		Do not store batteries for more than six months without charging. If the battery is stored for six months, it is recommended to charge it once. In addition, if the battery has been stored for three months, be sure to charge the battery with a protection circuit.

Cell Electrical Characteristics

No	Items	Test Method and Condition	Criteria
1	Rated Capacity at 0.2C(Min.)0.2C	The capacity of the battery should be measured after standard charging. This measurement should be performed by discharging the battery at a rate of 0.2 times the battery capacity (0.2C) until the voltage reaches 3.0 volts.	≥1765mAh
2	Cycle Life	The battery should be charged at the standard rate of 0.2 times its capacity (0.2C) until the voltage reaches 4.2 volts. It should then discharge at the same rate until the voltage drops to 3.0 volts. This charge and discharge cycle should be repeated continuously for a total of 300 cycles. After completing the 300th cycle, the capacity of the battery should be measured.	≥80% of initial capacity
3	Capacity retention	Batteries should be charged under standard charging conditions at a temperature between 20 and 25 degrees Celsius. After that, the battery should be stored in an environment with an ambient temperature of 20 to 25 degrees Celsius for 28 days. After the storage period, the capacity of the battery shall be measured by discharging at a rate of 0.2 times capacity (0.2C) at a temperature range of 20 to 25 degrees Celsius. The resulting capacity measurement will be considered the battery’s retained capacity after 30 days.	Retention capacity≥85%
