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

Attentions


For safety usage, please be careful on below:


Warning!


1. Do not immerse the battery in water and keep it dry when not using;

2. Do not strike, throw or subject the battery near a fire or in extremely hot conditions;

3. Charge with specified charge according to charging requirement;

4. Do not reverse the positive (+) and negative (-) terminals;

5. Do not put the battery into a fire or apply direct heat to it;

6. Do not short-circuit the battery by connecting wires or other metal objects to the positive (+) and negative (-) terminals;

7. Do not ship or store the battery metal objects, such as necklaces, hairpins, etc;

8. Do not knock, throw, tread, bend, etc;

9. Do not directly solder the battery terminals;

10. Do not pierce the battery casing with a nail or other sharp object.
