measured on 0.5C discharge till the voltage,discharge to2.75V, the capacity is ≥2800mAh
Cycle Life:
Charging and discharging battery as blew
conditions 0.5C standard charge to 4.2V end-off1C standard discharge to 2.75V cut-off Continuous charge and discharge for 500cycles ,the capacity will be measure after the 500th cycle
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 28 days with 0.2C at 20~25℃ as retention capacityThe battery to be charge in accordance with standard charge condition at 20~25℃,then storage battery at an ambient temperature 20~25℃ for 28 days.
Measure the capacity after 28 days with 0.2C at 20~25℃ as retention capacity the Retention capacity
should be over 80%

Period of Warranty
The period of warranty is one year from the date of shipment. We guarantees to give a ccin case of cells with defects proven due to manufacturing process instead of the customer abuse and misuse.
Storage of the Batteries
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.
Other The Chemical Reaction
Because batteries utilize a chemical reaction, battery performance will deteriorate over time even if stored for a long period of time without being used. In addition, if the various usage conditions such as charge, discharge, ambient temperature, etc. are not maintained within the specified ranges the life expectancy of the battery may be shortened or the device in which the battery is used may be damaged by electrolyte leakage. If the batteries cannot maintain a charge for long periods of time, even when they are charged correctly, this may indicate it is time to change the battery.
