Pretty good battery
I have purchased several of these batteries and they have worked just fine, but in the last batch one of the batteries only lasted two weeks, and now I am stuck with it because I can’t return it since it’s been 30 days since I purchased them

Prefect size, good construction
Fits perfectly and replaces the ones that came with the original unit.
