Li-Polymer 3.7V 25 Ah (75212223) Battery (DGR)


Untitled DocumentFeatures Tenergy Unique High-Capacity Li-Po Single CellHigh operating voltageEnergy density is high, volumetric energy density of 350Wh/L and gravimetric energy density of 135Wh/kg.No memory effectSelf-discharge is less than 10% per monthCharge/discharge cycle characteristics are excellentSafety characteristics are excellentThe battery has a wide discharging temperature range of -20 °C to +60 °CThe capacity in amp-hours is guaranteed, and will be exceeded most of the time. Item Spec Note Model 75212223/25000mAh Charge Voltage 4.2V End-of-charge voltage 4.2V CCCV Nominal Voltage 3.7V CellVoltage between 3.6V ~3.9V before shipping Nominal Capacity ≥25000mAh@ 0.2C Discharge Nominal Capacity refers to the capacity of0.2C discharge with 2.75V cut-off voltage, after charging with standard method. Cycle Life ≥ 300 Times One cyclereferto onecharge period and Then one discharge period.Test condition:Charge0.2C to 4.2V Discharge0.2C to 2.75VThe cycle life is the cycle times whenthe discharge capacity is about 80% of the rated capacity. Self-discharge Residual Capacity>90% After standard charging, storied at25°C±0.5°C for 30 days, then measure the capacity as item 4. Impedance Typical:10mΩMax15mΩ After standard charging, measure th internal resistance with AC1KHz Max. Charge Current 1.0C Max. Discharge Current 1.0C Discharge Cut-off Voltage 2.75V Operating Temperature Discharge:-10℃~ +60℃Charge0 ℃~ +45℃ Cellsmust be storied at 3.6V-3.9V. During long period storage, cells should be maintained every 90 days. The method is to do a charge-discharge cycle with standard method, then charge to3.7—3.9V. Storage Temperature -20 ℃~+45℃ Cell Weight Approx 0.65Kg Cell Dimension Length:223mm Max Width:212mm Max Thickness:7.5mm Max Measured with weighting 300gf at25℃ 0.5℃ Not including Tabs Cautions CAUTIONwhen working with Li-ion cells, they are very sensitive to charging characteristics and may explode if mishandled.User should have enough knowledge on Li-Ion rechargeable batteries in charging, discharging and assembly before use.We are not responsible for any damage caused by misuse or mishandling of these Polymer Li-Ion batteries3.7V 25000mAh (75212223)Datasheet
