Description
LG INR18650 MJ1 Lithium-Ion Cell
Single cylindrical rechargeable lithium-ion cell, model INR18650 MJ1, button-top terminal. The product listing identifies it as an 18650 cell.
- Model: INR18650 MJ1
- Format: 18650
- Nominal voltage: 3.635V in LG Chem’s specification (the source listing says 3.7V)
- Capacity: LG specifies 3500mAh nominal and 3400mAh minimum; the listing claims 3400mAh (±9%)
- Standard charge: 0.5C (1.7A) to 4.2V, then constant voltage with current taper, per the manufacturer specification
- Maximum charge current: 3.4A per manufacturer specification; the source listing instead states 2A maximum and recommends 1A
- Terminal: button-top, according to the listing
- Weight: 47g, according to the listing
The manufacturer specification describes a 400-cycle test with at least 80% of minimum capacity under its defined high-drain conditions; the source listing claims 500–1000 charge cycles. These are different claims and depend on test conditions.
Listing inconsistency: the French product is configured as a simple item, but its attribute also lists 3000mAh and 3400mAh without separate product variations. The title and model identify the MJ1; verify the exact cell and capacity marking. The listing’s 3400mAh figure is the manufacturer’s minimum capacity, not its nominal rating.
Use only a suitable lithium-ion CC/CV charger configured for this cell, with correct polarity. Never short, crush, puncture or expose the cell to heat; stop using it if damaged, swollen or unusually hot. Keep it away from metal objects that could bridge the terminals. The product is sold as a single cell.
