The is the button top version of the cell.










Good tracking between the cells and also constant capacity at any load, this looks good.














Flat top version

The is the flat top version of the cell.



This version also has good tracking between the cells and also constant capacity at any load, this looks good.
I expect they are using the same cell, i.e. they must have the same performance.






















Conclusion

The batteries has a good capacity for IMR batteries, even though it is lower than rated. The performance is also good, even at much higher current than they are rated for.
There is a very small difference between flat top and button top, the button top increases the resistance slightly.
I will rate this battery acceptable.

Thanks for the test info, it’s very Appreciated.

Excellent as always sir!

Group buy! :smiley: This product is no longer available.

Manufacturer/seller site, you can buy singles there (or so it says)

I do not understand the protection test :frowning: What does this mean? It has protection and it works?
Thanks for clarifying!

It has no protection.

In the protection I increase the current until the protection trips or I hit my limit (7A in this case). The curve will stop when the protection trips. Here it does not stop but continues all the way to the limit, i.e. not protection or it has a very high limit. Being an IMR cells it is no surprise that it is missing a protection.
