I own 1x 5100 and 2x 5150. They appear to have the same lens, same darkness, and overall the same performance. They have the same fit and shape (as far as eyes, nose, band, ears are concerned). The 5100 has a mass of 23.0g, 5150 is only 22.5g. Likely the same mass except for the different cell size.
Speaking of, and as you mentioned, both glasses use 1x 3 volt lithium primary button cells. 5100 uses CR2025, 5150 uses the smaller CR1620. For those unfamiliar, a CR2025 is 20mm diameter by 2.5mm thick, CR1620 is 16mm x 2.0mm.
That might lead one to think that the 5150 wouldn't last as long, if only for a lower capacity cell. It seems likely that Samsung revised the wireless chip to make up for the difference, though.
I haven't spent any time looking, but it may be possible that one of those cells is more commonly available than the other (I think CR2025 might be more common).
The 5100 have a nosepiece that slides/hinges open almost like a CD Walkman, whereas the 5150 uses a twistlock cell door that is turned with a coin or stiff thumbnail. I suppose the cell door on the 5100 is far more easy to accidentally break. Something to consider if the person/people changing the cells might be clumsy or lack finesse.
In summary, they are effectively almost identical except for the cell.
I have experienced poor cell life with both models. I have had all three for just over a year, having viewed about one or two dozen hours of 3D. They are all now dead, so on the 5150s, I've moved on to the included spare cell. It almost seems like the glasses have a small vampire draw when powered off (so they'll die in a year whether used or not)
Oh, one more thing. The 5150 comes with a spare cell, whereas (if I'm remembering correctly) the 5100 only came with one cell. Certainly a convenience, when the cells are so expensive if purchased at a drugstore.
Any other questions?
