Can i use this with a aaa lithium battery or does it really need to be alkaline?

Use rechargeable AAA batteries. These small bright flashlights eat batteries. Each battery only lasts 40-45 minutes; tops. Alkaline AAA start out brighter because they are at ~1.60 volts DC. Rechargeable AAA batteries start out at ~ 1.42 to 1.45 volts DC depending on your charger. Difference in runtime is noticeable, but negligible. These lights are not meant as a main light for more than 30 minutes. They are primarily for intermittent use. The cheaper ThruNite Ti2 will NOT work with rechargeable AAA batteries.

Header description says i4e, detailed description says i3e. why the difference?

Hi dear customer, the correct name is "I3E", not "I4E". We're so sorry for this. This is the display problem with Amazon system. We have already responded to Amazon. Thanks!

Does anyone know the runtime with a non rechargeable lithium battery?

I’ve had mine for almost 3 years the standby is amazing, I’ve only changed the battery once, it lights up every time without fail. I’d say continued use maybe like 30 minutes

Se puede usar TR 10440?

Sorry, it can not use. The voltage is beyond 2v, we do not recommend use. Thank you!
