Xtar 18700 2400 mAh (Black)



Official specifications:

• XTAR 18700 2400mAh Protected Li-ion Battery
• Voltage: 3.7V
• Battery Capacity: 2400mAh
• Size(mm): 68.90 (length) x 18.30 (body diameter)
• Net Weight: 47g

The battery is called 18700, because it is nearly 70 mm long, but protected 18650 can be just as long, only unprotected batteries are 65 mm long.








The protection does not allow the battery to sustain 5A current draw.











The two batteries has slightly different internal resistance and trip current (This might be related).





Conclusion

This battery is best for lower load and easily holds the specified capacity.
It is using a unspecified cell, but with Xtar behind it I will call it good battery.
