Test/Review of Xtar 18700 2400 mAh (Black)

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.

thanks!

Am I correct in comparing this with the 2600mAh test that this one has more capacity up to 3A discharge? This 2400mAh battery measures 2410 at 3A discharge and the 2600mAh measures 2377mAh at 3A (I know - pretty much the same capacity). I guess what I am saying is that it seems these 2400's are just as good as the 2600's if you are only discharging at 3A or less. Save a little money buying the 2400's then?

Yes, these the capacity of these batteries looks very good, but you has to stay below 3 to 4 ampere. You can also see it in my summary thread.

@HKJ: I'm just gonna post here but this could be put under any of your threads: thanks for your work, it's really REALLY appreciated. One can hardly guess how much work it is for only one battery, but you are doing so many.. so.. well, thank you. I'd hug you if you were here. :P

Good to see some results from the XTAR's. This seems to agree with what Old4570 (I think that's who it was) found when he compared 2400's and 2600's. They were almost the same capacity. But the 2600's are Sanyo cells and are supposed to do better under load.

Instead of (black) you might call them (blue) because the writing on the label is blue. All of their cells, I think, are black. At least the 2600's are. Maybe the 2200's aren't though.
