Pretty much nothing uses NiCad batteries any more, even before the RoHS regulations restricted the products that NiCad batteries could be used in due to their low energy density and complex maintenance requirements.
Pretty much everything electrical that you can pickup is powered by Li-ion batteries these days, E-Cigs and Vapes included.
Lithium disposable and Lithium-Ion rechargeable batteries are considered to be the same by air transport restrictions anyway.
I stand corrected.. didn't realize they were Lithium
