Are alkaline or lithium batteries better?
user
Alkaline batteries are more common and tend to be cheaper than lithium batteries, but they don’t last as long.  Many lithium-ion batteries can last for ten years, while alkaline batteries are typically much less reliable.  Which do you have now?
assistant
So are the lithium worth the extra money then?
user
They are if you need to have a battery that lasts a long time.
assistant
So if I don't want to change it often lithium would be the way to go?
user
Right, but if you want a battery that will last a long time you should definitely go for lithium.  Lithium is much more common than alkaline batteries are, but they are much more expensive than the typical alkaline batteries.

Unless you need a battery that only lasts a few months, then an alkaline battery might be better.  Lithium-ion batteries have a higher cost per battery cycle.
