Test Conditions

Electrical Characteristics & Test Condition
Testing Conditions: Ambient Temperature: 25±5℃; Huminity:45%~75%.

NO	Items	Criterion		Condition
1	Min Capacity	≥250Ah		Rest for 1 hour after fully charged, then discharge with 0.33C current until the battery reaches the cutoff voltage. you can stop and define the Discharging current*time value (Ah) as battery capacity.
2	Cycle life (DOD%100)	≥2000cycle		Charge / CC(0.33C)/CV(14.6V); End current : 0.05C; Rest time : 1h; Discharge / CC(0.5C); End voltage : 8.0V; Repeat above process until discharge capacity is no more than 80% of normal value. Accumulated times is defined as cycle life.
3	Discharge Temperature Characteristics	-20℃	≥70%	At 25±5℃ discharge the battery with the current of 0.33C to the cut-off voltage. Store the battery at various temperatures for 2h and discharge the battery with 0.33C to the cut-off voltage. Record the ratio between discharging & charging capacity.
		0℃	≥80%
		25℃	100%
		55℃	≥95%
4	Charge Retention ability	remain capacity≥90%		Charge the battery to full capacity and store it for 28days, and then discharge it with 0.33C to the cut-off voltage.

 

 

 

 

Features:
The battery uses imported original big brand ion batteries, with a small internal resistance, big capacity, cycle times and more, no memory effect, etc; internal circuit for multiple protection design, can prevent over charge, over discharge, over current; production process quality inspection and monitoring the use of computers to ensure superior battery performance.

How to choose a suitable battery pack?

• battery voltage is the same with the original.
• battery size same with the original. Or similar/smaller.
• battery plugs same with the original (check the plug diagram)

Match the above three conditions, in general, this battery can be used.

The larger of MAH, the longer use time. Different voltage, battery size, shape, can be same voltage, because the battery combination of different ways, the shape is not the same. You can leave a message about your old battery, please pay attention!!!
