3. Performance Comparison: OEM vs. Aftermarket Batteries
How Do OEM and Aftermarket Batteries Perform Differently?
- Cell Type Comparison: OEM batteries often use 18650 cells, while many aftermarket batteries use 21700 cells. The 21700 cells offer higher energy density, allowing the battery to provide longer run times within the same volume.
- Runtime and Power Performance: Through real-world testing, we compared how both OEM and XNJTG aftermarket batteries perform under load. The results indicate that aftermarket batteries tend to deliver longer run times with similar power output, providing better cost-efficiency.
| Battery Model | Cell Type | Max Capacity | Avg. Runtime (Standard Load) | Avg. Temperature Performance |
| OEM 8.0Ah | 18650 | 8.0Ah | 1.5 hours | Moderate |
| XNJTG MAK-40V-LI-10-21700 | 21700 | 8.0Ah | 2.0 hours | Lower |
- Temperature Control and Stability: Aftermarket batteries often feature more advanced thermal management systems, ensuring stable performance in extreme conditions (high/low temperatures), which reduces the risk of overheating or freezing that can shorten battery life.
