Looking very careful on the shrink wrap, it is possible to see the battery type.

I am not very impressed with the capacity, but the voltage is high compared to 4.2 volt batteries.

Test at 4.3 volt charge

Reducing the charge voltage to 4.3 volt, looses about 120mAh in capacity.

At 4.2 volt, the capacity is down with about 360mAh and the voltage advantage is gone.

Conclusion

Being a Sanyo battery it is very good, but I wonder about the low capacity, it might be due to age (If I read the datacode correct the battery is from 2010).
