Difference of LF280 and LF280K
1.Dimension(Height and Tabs Distance)
Height:
LF280: 204.8*72*173.6mm VS LF280K: 207*72*173.6mm
Tabs distance:
LF280: 90±0.3mm, LF280K: 123.0±0.3mm
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±2)℃, 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
