Lithium VS Titanium

The so-called titanium are just alkaline batteries with a higher price tag and maybe some slightly improved chemistry. Performance difference as measured on CPF is quite small. Lithiums really are a lot better than alkalines but the voltage is a little higher and they're very expensive. Really it's best to use NiMH for almost everything unless there are specific reasons to use something else.
 
The titanium line are just slightly improved alkalines, with only a very slight improved runtime. No improvements in storage or heat affects, like you get with lithium.
