| Dimensions | 310 x 114 x 15 mm |
| Weight | 887.8 g |
| Capacity definition
The nominal capacity originates from the manufacturer’s data sheet, if available. When the data sheet is unavailable, the nominal capacity is estimated. Batemo measured the C/10 capacity by discharging the cell at an ambient temperature of 25°C from 100% with a constant current of 6.00A (0.1C) until reaching the voltage of 2.7V. The thermal boundary condition is free convection. |
nominal 60.0 Ah C/10 61.1 Ah |
| Current definition
All quantities are measurement results from the Batemo battery laboratory. The continuous current is the highest current that completely discharges the cell without overheating it. Therefore, the cell is discharged from 100% state of charge (SOC) at an ambient temperature of 25°C with a constant current until a residual state of charge of 10% and either the lower voltage limit of 2.7V or 90% of the maximum surface temperature (54°C) is reached. The peak current is the current that the cell can supply for 5 minutes. The cell is therefore discharged from 100% SOC at an ambient temperature of 25°C with a constant current until it reaches either the lower voltage limit of 2.7V or the maximum surface temperature of 60°C after 5 minutes. For cells that reach the maximum surface temperature, the measured current is taken directly as the peak current. For cells that do not reach the maximum surface temperature after 5 minutes because they reach the lower voltage limit first, the measured current is multiplied by a correction factor that estimates the current that would have heated the cell to the maximum surface temperature within 5 minutes. The thermal boundary condition is free convection. These operating conditions may be outside the cell manufacturer’s specification. |

All quantities are measurement results from the Batemo battery laboratory. The continuous power is the highest power that completely discharges the cell without overheating it.
