TAFEL 139AH CELL
01139Ah Nominal Capacity
The cell combines 139Ah nominal capacity with a 3.65V nominal voltage, providing approximately 507.35Wh of calculated nominal energy per cell.
02Stated Maximum Discharge Rate
A maximum discharge rate of 3C corresponds to 417A based on 139Ah. Confirm the permitted duration and operating conditions before selecting the cell for a load profile.
03Prismatic Aluminum Housing
The rectangular aluminum housing can be considered for space planning in custom modules. Two stated dimension sets are available and require confirmation against the actual cell version.
04Approximate Cell-Level Specific Energy
Using the stated nominal energy and approximate 2.4kg cell weight, the calculated cell-level specific energy is approximately 211.4Wh/kg.
TAFEL 139AH CELL
This 139Ah NCM cell may be evaluated for custom mobility, industrial power or energy-storage battery projects. Suitability depends on the application’s load profile, available space, temperature conditions and system-level requirements.
Before selection, confirm the exact cell model and dimensions, terminal arrangement, current-rating duration and available batch documentation. A completed pack requires an appropriately designed BMS, cell monitoring, electrical protection and thermal management.

Is 417A a continuous discharge rating?
The stated maximum discharge rate is 3C / 417A, but its duration has not been confirmed. Please verify whether it is continuous or time-limited before designing the system.
Which dimensions apply to the supplied cell?
Two dimension sets have been provided: 44 × 220 × 103mm and 44.5 × 220 × 102mm. Confirm the exact version and dimensional drawing before ordering.
How is the 507.35Wh energy figure calculated?
It is the approximate nominal energy calculated by multiplying 3.65V nominal voltage by 139Ah nominal capacity. Actual usable energy depends on operating conditions and system design.
