1 Preface
This specification describes the type and size, performance, technical characteristics, warning and caution of the prismatic power cell. The specification only applies to IFP23140160-50Ah cell supplied by HEFEI HOYE ECOLIENG TECHNOLOGY CO., LTD

2 Definition
2.1Rated capacity:
Rated capacity=50.0Ah: The capacity obtained when a cell is discharged at 1C to
2.5 volts at 25 ± 2.5℃

2.2Standard charge method:
At 25 ± 2.5℃, charge to 3.65V at a constant current of1C, and then, charge continuously with constant voltage of 3.65V until the charge current drops below 0.05C.
2.3Standard discharge method:

At 25 ± 2.5℃, discharge to 2.5 V at a constant current of 1C.
2.4Standard discharge method:
From the date of production to the time when the capacity decreases to 80% of the initial capacity

7 Storage and qualitywarranty
7.1For different storage environment,pls check followingform

Temperature Storage time SOC capacity rentation
-20~35℃ ≤6 months 30%≤SOC≤60%
35~45℃ ≤3months 30%≤SOC≤60%

7.2 25storage

Storage time 30days storage 60days storage 90days storage 180days storage
Voltage drop standard/mV ≤5 ≤8 ≤10 ≤20

Shelf life: calendar life of 10 years or cycle life of 2000 times (based on first come) Regular maintenance
For storage cores that have been used for more than 6 months, the starting time is the delivery time of our cores; if regular maintenance is required, 0.5C current constant charging should be carried out to 3.6V, 3.6V constant voltage to 0.05C, 0.5C constant current discharging to 2.5V after 10 minutes, 0.5C constant current charging to 3.2V after 10 minutes, 3.2V constant voltage charging to 0.05C, and the process ends. If abnormal cores are found in the maintenance process, we should contact our company to deal with them in time

9.Warning and cautions in handling the lithium-ion cell
To prevent the possibility of the cell from leaking, heating, explosion, please observe the following precautions:
Don’t immerse the cell in water.
Don’t use and leave the cell near a heat source, such as fire or heater. Don’t discard the cell in fire or heater.
Don’t connect the positive and negative terminal directly with metal objects.
Don’t transport and store the cell together with metal objects such as necklaces, hairpins. strike, throw or trample the cell.
Don’t directly solder the cell.
Don’t pierce the cell with a nail or other sharp object.

 

Caution

If the cell leaks and the electrolyte get into your eyes, don’t wipe eyes, instead, thoroughly rinse the eyes with clean running water for at least 15 minutes, and immediately seek medical attention. Otherwise, eye injury can result. If the cell gives off an odor, generates heat, becomes discolored or deformed, or in any way appears abnormal during usage, recharging or storage, immediately remove it from the device or cell charger and stop using it.
