I haven't really seen the use of switching to a Lithium rechargeable from my Eneloop standard/pro's. They are new to the market and seem super expensive. Also the major players in the rechargeable AA/AAA market (Energizer, Eneloop, Ikea Ladda, etc) haven't offered a Lithium version yet that I've seen, so can't exactly compare quality with so few competitors.
That said, I have heard of Tenavolt. Very little reviews on Amazon (not hard to hit a good rating in only 40 reviews if paid, decent if not). Reviews say they last a while but die quickly once they hit 70% which makes sense because they're intended to hold a constant 1.5v through the full charge instead of dropping voltage slowly like traditional rechargeables. They claim fast charging at less than 2 hrs, 1000 cycles, and high capacity.
If you're using rechargeables right then you don't care how fast they charge since you should always have fully charged backups ready to swap in immediately while you charge the dead ones. So that's not really a benefit to me.
The capacity is a bit confusing. Most of the references on Amazon say mWh instead of mAh, the standard metric used for battery capacity. Though I did find one picture that references mAh. If mWh is an error and they are truly mAh, then we can compare to others and the values advertised are higher than any other rechargeable AA/AAA I've seen. For AA, Tenavolt claims 2775 mWh/mAh versus Eneloop Pro's 2600 mAh. For AAA, Tenavolt claims 1110mWh/mAh versus Eneloop Pro's 980 mAh. So not really a big difference, but higher. A quick search on Amazon shows others advertising as much as 3600 mAh AA's, but there doesn't seem to be good third-party testing to verify claims of lithium batteries yet.
1000 cycles is twice as many as advertised for Eneloop Pro's, while also having higher capacity than the pro's. Still half the cycles of standard Eneloop, but 1000cycles for that high capacity seems great.
At $8.75/battery regular price, the Tenavolts don't offer enough benefit to justify the price to me. $3.50/battery from this deal is much more reasonable, but again without a lot of data out there to backup claims, not sure these are really better than Eneloop Pro.
Worth a shot?

The last time I looked into this kind of battery, I discovered that they had a lot of problematic issues. I doubt anything has changed in the last two years, or they would be more popular.
Bad in low-drain usage
Bad longevity (few recharge cycles before they die)
Debouncing issues when empty
Expensive, low-value
A word of caution is that you need to keep these separate from NiMH rechargeables and not accidentally use them in a standard charger, only with a charger designed for lithium. Never did it but recall reading that not only would it not work but could potentially damage the battery or worse. Also, likewise probably damage NiMH if used in the Tenavolt supplied charger..
