Cycle Life
|
Charging and discharging battery as blew conditions 0.2C standard charge to 3.65V end-off 0.2C standard discharge to 2.0V cut-off Continuous charge and discharge for 500cycles ,the capacity will be measure after the1500th cycle
|
≥80% of initial capacity |
|
3 |
Capacity retention
|
The battery to be charge in accordance with standard charge condition at 20~25℃,then storage the battery at an ambient temperature 20~25℃ for 28 days. Measure the capacity after 30 days with 1C at 20~25℃ as retention capacity
|
Retention capacity ≥85% |

This battery pack is specially design for Mobile Radio, the LIfePO4 batttery pack can used for wide range device by assembled to various size\ voltage and capacity.
15-25days after order confirmed and the buyer arrange the payment
Battery Pack was protected by double thick plastic bag one by one,
3 sets for one strong paper carton
The outer carton stick Standard international transport label with UN38.3 certification
The batteries should be stored at room temperature, charged to about 30% to 50% of capacity.
We recommend that batteries be charged about once per half a year to prevent over discharge.
The period of warranty is one year from the date of shipment. TAC guarantees to give a replacement in case of cells with defects proven due to manufacturing process instead of the customer abuse and misuse.
