Discharge performance in normal temperature
Discharge capacity /standard capacity×100％
Charge with 0.2C5A standard charge in the condition of temperature 25ºC±5ºC, relative humidity 45％～80％ (if there is no especial statement, the charging way is same as this. ) Keep it for 10min and separately discharge with 0.2C5A &1C5A to cut-off voltage 7.5V, cycles for three times. One cycle capacity arrive standard, that’s to say it is qualified. (The below as the same)
Charging keep ability in normal temperature
Rest capacity≥standard capacity *90％
After standard charging，store it at 25ºC±5ºC for a month, and then discharge it to cut-off voltage7.5V by 0.2C5A. Then measure the capacity of cell.
Capacity≥ Standard capacity *80％
After 0.2 C5A standard charged ,discharge it with 0.2 C5A to 7.5V.rest for10min, cycles for 2000 times.
Capacity can be kept ≥80% Storage for 12months.
After standard charged, keep it for 12 months as a open circuit, discharging it until 7.5V by 0.2C5A, and then measure the leftover capacity. Measure its recovery capacity by 0.2 C5A /0.2C5A . Undertake 3 cycles, it passes when one cycle meets the standard.
Storage and Transportation
Based on the character of cell, proper environment for transportation of LiFePO4 battery pack need to be created to protect the battery.
During transportation, 50% SOC must be kept to ensure that short circuit, appearance of liquid in the battery or immersion of battery in liquid never occur.
Battery should be kept at -20℃～60℃ in warehouse where it’s dry, clean and well-ventilated.
During loading of battery, attention must be paid against dropping, turning over and serious stacking.
Warnings and Notice
In order to prevent the battery leaking, getting hot and exploding, please pay attention to preventing measure as following:
Never throw the battery into water, keep it under dry, shady and cool circumstance when not use.
Never upside down the positive and negative.
Never connect the positive and negative of battery with metal.
Never ship or store the battery together with metal
Never knock, throw or trample the battery.
Never cut through the battery with nail or other edge tool.
Never use or keep the battery under the high temperature. Otherwise it will cause battery heat, get into fire or lose some function and reduce the life. The proposed temperature for long-term storage is 10-45ºC.
Never throw the battery into fire or heating machine to avoid fire, explosion and environment pollution; scrap battery should be returned to the supplier and handled by the recycle station.
Never use the battery under strong static and strong magnetic field, otherwise it will destroy the protecting device.
If battery leaked, the electrolyte get into eyes, please don’t knead, please wash eyes by water and send to hospital. Otherwise it will hurt eyes.
If battery emit peculiar smell, heating, distortion or appear any unconventionality during using, storage or charging process, please take it out from device or charge and stop using.
Never cut the battery in socket directly; please use the stated charger when charging.
Check the voltage of battery and relevant connectors before using the battery. It can’t be used until everything turns out to be normal.
Before charging, fully check the insulation, physical condition and aging status, since breakage and aging are never allowed; the pack voltage must not be less than 7.5 V, if not, it’s abnormal and that battery needs to be labeled. The user should contact our Customer Service Dept and It can’t be charged until repaired by our staff.
The battery should be stored in half SOC. It needs to be charged once if not using for as long as half a year.
Clean the dirty electrode, if any, with a clean dry cloth, or poor contact or operation failure may occur.
