Not many that I have personally, but my current clamp ( uni-t 210E) starts reporting wrong numbers when the cells are under ~1.45V, it’s really bad. My meteo station modules seems to have a high cut off, although not as bad.
I’m wary of the potential self discharge rate of a li-ion cell coupled with a voltage converter, but more importantly they are extremely expensive.
One of my old Canon digicams would show low battery almost immediately (maybe take a half dozen photos first, that’s about all) with any NiMH. I put some lithium primaries in and they were good for a couple hundred pics.
Some devices don't really like NiMH batteries because of their voltage, but that doesn't mean they still are one of the best rechargeable NiMH batteries on the planet..
“Japan technology” would not be on the packaging. Plus some other details like the graphics don’t look right. Shame on people for copying Eneloops. Plus, correct me if I’m wrong, but the LSD Eneloops are made by FDK I believe. No one else makes them to my knowledge since it’s a trade secret.
The fake package mentions Min. 800mAh, which I have never seen on any AAA package.
Also, Japan Technoly.... whatever that means.
So funny to see the backside of the Chinese made Eneloops d_t_a ... it says with large letters: Eneloop Technology from JAPAN to the world.. but are made in China. Just an interesting detail I just noticed.
When I was a kid growing up in Sweden, the label on the honeyjar said in large writing, “Authentic Swedish Honey” and in smaller writing, “Made in Hungary”
