Difference of LF280 and LF280K

1.Dimension(Height and
Tabs Distance)


LF280: 204.8*72*173.6mm VS LF280K: 

Tabs distance: 

LF280: 90¡À0.3mm,  LF280K: 123.0¡À0.3mm

2.Cycle Life

LF280: 3500cycles,   LF280K: 6000cycles

(Under the 300kgf clamp, after standard charged and 30mins rest, discharge to 2.5V cut-off with the current of 0.5CA at (25¡À2)¡æ, and then start the next cycle. end with the capacity decreasing to 80% of the initial capacity. The number of cycles is defined as the cycle life of the battery)

3. Max. charge / discharge current

LF280: 1C,  LF280K: 2C
