Rechargeable cylindrical Li-ion cell
A 6000mAh, 21Wh 21700-format cell engineered to unite high energy with strong discharge capability. The 60Q supports up to 60A discharge at room temperature, 12A maximum charging and a 150A pulse for 2 seconds under the specified conditions.
INR21700 / 60Q Specification Rev. A - May 5, 2026
Core ratings are stated under the test conditions defined in the product specification. System-level performance depends on cell temperature, pack design and control strategy.
Electrical, mechanical and environmental parameters for engineering evaluation and pack integration.
*The 110A temperature-cut discharge and 150A/2s pulse ratings are specified as not for cycling.
Relative capacity results from the specification help engineers compare output across discharge rates and temperatures.
| Discharge current | 1.2A | 6A | 18A | 30A | 50A |
|---|---|---|---|---|---|
| Relative capacity at room temperature | 100% | 97% | 95% | 95% | 90% |
| Discharge temperature | -40°C to 2.2V | -20°C | 0°C | 25°C | 60°C |
|---|---|---|---|---|---|
| Relative capacity at 6A | 50% | 70% | 85% | 100% | 100% |
Cycle results are tied to the exact charging, discharge, rest and temperature limits shown below.
| Charge condition | Discharge condition | Rest periods | Specified result |
|---|---|---|---|
| 6A CC to 4.2V, then CV to ≤300mA | 6A CC to 2.5V | 10 min after charge; 30 min after discharge | ≥80% initial capacity after 800 cycles |
| 6A CC to 4.2V, then CV to ≤300mA | 30A CC to 2.5V or 75°C | 10 min after charge; 30 min after discharge | ≥80% initial capacity after 300 cycles |
The specification reports no explosion and no fire under its defined forced-discharge, overcharge, external short-circuit, drop, heating and crush test methods.
This is a rechargeable Li-ion cell, not a protected consumer battery. Use only with a validated battery-management system, suitable current protection, qualified thermal design and a charger configured for the stated limits. Do not short-circuit, crush, disassemble, immerse, reverse-connect or expose the cell to fire. Do not mix cells of different makes, types or models.
Specifications shown here summarize Amprius INR21700/60Q Product Specification Rev. A dated May 5, 2026. Verify the latest manufacturer specification and validate performance in the final pack before design release.
