These are non-rechargeable, so I suppose they are supposed to compete with teh Energizer Ultimate Lithium batteries. Project Farm does a video where he compares other non-rechargeable AA Lithium batteries to the Energizer ones.

Read the one star reviews. After removing the fake ones, these must suck, especially at the premium price.
3500mAh at standard LiIon voltage would of course be absurd in the size of a AA. I'm not sure what the marketing psedo math is here. Maybe they mean 3500mWh. Which would still be high.
Anyway these typically use a buck converter to step down the the 3.7V of LiIon down to 1.5V, and that circuit remains active regardless of load, resulting in a strong self-discharge effect. Making this quite poor for a low drain device like a tv remote.
They can work well in high drain digital devices that are sensitive to voltage drop, cause they're going to give you 1.5V until they suddenly die. But I'd choose a more reputable brand.
Edit: As someone points out below, these are non-rechargable lithium batteries, so most of the above does not apply.

They figure the average person won't know the difference, so good to point it out when you see it.

This is Lithium-metal battery, which is generate 1.5V naturally. It does not need the dc-dc converter. That is why it can pack this huge amount of 3500mAh. For the Lithium rechargeable battery, the voltage is 3.7V, it will need the dc-dc converter. And it capacity is limited.

Totally missed that, thanks. In light of this, the reviews about dead batteries after a week are pretty alarming.
