Most durable 18650 battery?

Hi all, I was wondering what the longest lasting 18650 battery is and how long it would last in a UniqueFire UF-2160 or UniqueFire UF-2100 flashlight (both 1000 lumens)?

Panasonic's are great, they should last for several years when properly maintained.

Thanks for the suggestion. Are they the longest lasting batteries or are there others that would last even longer?

The best I know of.

Okay, thanks for your input.

Do you mean durability as in lifetime or are you talking about capacity?

Lifetime. What exactly would capacity be? (I'm a total noob with flashlights so sorry if it's a stupid question)

How much power it can put out for how long. Aka a 3100 mah battery can power your flashlight longer than a 2400 mah battery.
