The fact is that 1.5V Li-ion batteries are just not great. Chemistry determines the voltage. Alkaline is 1.5V, NiMH is 1.25V. Li-ion is 3.2 or 3.7V, so they use a buck converter to step it down to 1.5. This (as far as I am aware) means you can't (or shouldn't) use a "standard" NiMH/Li-ion charger. It's why you frequently see these with USB-C ports on them, or they come with their own special charger. Furthermore, buck converters are notorious for phantom drain, so the bad reviews indicating poor battery life make sense.
A more respectable manufacturer might use better converters, but I'm not sure I'd buy any 1.5V Li-ion: https://www.amazon.com/EBL-Lithiu...B0DK2N
If you have a device that simply must have 1.5V and can't use the 1.2-1.3V NiMH, just buy alkalines. Otherwise, use quality NiMH and call it a day.
Anyone using these in their external blink cams ?
You CAN get AA size lithium batteries, but they WLL fry most 'normal' AA driven devices.
The capacity for lithium is often give in mWh, which is why you see that instead of mAh. It is actually 'more' correct, but also confusing.
The buck driver/step down maintains the 1.5v (good), but at the expense of voltage conversion losses, heat production, electronic interference, and increased voltage losses over time (not good).
HOW MUCH of each of those compromises varies WILDLY among the hoard of batteries out there.
Xtar is very good. Hixon is good, Tenavolt is decent, EBL....and the new myriad of 'no name' Chinese batteries making exaggerated claims, not so much.
