Nearly OEM for way cheaper
These have been great backup batteries overall, and perfect for the price. I haven't noticed any usage issues with my M50 Mark II with these (on-time seems about the same). The only point against them is that it seems like the OEM battery holds a charge longer when not in use, so I have to remember to top them off the night before if I've got a big day planned. Not sure if it's phantom drain or something about my use case causing it though.
