This is a AA sized LiIon cell. As a LiIon cell it has 3 times the voltage of a NiMH cell and about 1/3 the capacity, i.e. the energy contents is about the same.
The cell is not designed for high current, but for capacity.

The marking is added by the dealer, the actual Sanyo marking is present, but very difficult to see (As usual for Sanyo).

The cell does very good up to 1A, but above 1A it runs into problems.

Conclusion

This cell is very good, but the performance is slightly below other copies of the cell I have tested, probably because it has been in storage for some time.
