STRANGE: 2 TrusFire 14500 Flames Differ by 2mm in Length

STRANGE: 2 TrusFire 14500 Flames Differ by 2mm in Length. I'm pretty sure I bought these from the same place. They both seem to work OK. Is this kind of variation normal??

protected?

I always use protection. Hehe.

Kuma, check the bottom of the cells. Do they look the same? If not, longer one prob has a protection circuit.

The longer one is a somewhat smaller diameter at the bottom.

Definitely sounds like those are protected.

EDIT

In which case yes, it's perfectly normal
