This battery has a very solid build, the disadvantage of this build is the length of the battery.





The button top is high and larger in diameter than normal button tops.




The battery has a clear outer wrapper.

















Conclusion

This battery uses a very good cell, but does not fit in all equipment due to the length.
I will rate this battery very good, with the exception of the length.
