Well, primary lithium cells are among the highest shelf life commercial batteries. If shelf life is important, why are you running on rechargeable?

- dmritard96 9y agoI'm not - we ship our stuff with alkalines. but regardless of what current chemistries are best at today, one time use blows. Lets say we get 1 year on our alkalines and would get 1.8 years on lithium, after just a couple years, I will have one or two sets of battery waste even though we are specc'ing our hardware for at least 6 years (when we expect a decent number of units flash memory to start dying. There aren't yet good reusable batteries with good shelf life but there are plenty of applications where that would substantially prevent waste and generally make things simpler. I'm agnostic/indifferent to chemistry (assuming their externalities are similar, which they're not btw), but having a few AAAs for my whole life would be fantastic and probably reduce the environmental consequences of society quite dramatically.

Their self-discharge characteristics are pretty decent. 6 years is probably pushing it, I guess.
- dmritard96 9y agoYeah these aren't bad. Only complaint on these is the discharge curve. For some reason they run a little low for their middle voltage range making them work for devices designed/spec'd to run at that lower voltage point. Out of curiosity, anyone know any good sources for ultra low power consumption battery performance charts? Does anyone publish these?
