ICR cells - also called regular Li-ion batteries, LiCo, unprotected lithium batteries, protected lithium cells - are now obsolete and should not be used for any ecig application.
Only use IMR or hybrid cells now. IMR = LiMn, lithium manganese rechargeable. Hybrid = lithium hybrid chemistry rechargeable.
The brands that can be found include AW, MNKE, Sony, Efest, Panasonic, Samsung, Orbtronic.
Basic Li-ion cells (ICR) should no longer be used for any electric/electronic vaporizer application.
It doesn't matter if they are protected or not - they are RIP.
