These batteries are called IMR but their rated high current capability is fairly low for IMR cells.










The batteries show very good tracking and fairly constant capacity, they do also work fine at 10A.















Conclusion

They have a good performance, but cannot match some moderen high current cells.
I will rate them as acceptable.
