That is what’s normally quoted, whilst a LiIon is nominally 3.7V. But just as an aside (this is one of my bugbears), that’s using completely different definition for nominal voltage – the nominal voltage quoted for disposable batteries is the voltage when fully charged, whilst for rechargeables it’s the voltage mid-discharge. I suppose I should use 4.2V for the “disposable” LiIon on that basis, though for doing calcs it’s better to use the mid-discharge voltage of the alkaline, which is ~1.2V, much the same as NiMH.
I just find the whole thing rather repulsive though.
It is, but I’m struggling to raise my piss above the temperature of a warm bath, even when only compared with other consumer waste involved in portable electronics (says the man about to dispose of a smartphone which is less than 4 years old – though that’s probably still older than what most of you lot have).
😯 – I’m betting more go into landfill than recycling.
