I don't use recharbles and/or alkaline except in the summer months. But I, don't use headlamps that much in the summer so they don't get that much use.
I do use them a lot in the other three seasons where the daylight hours are less.
Recharbles don't work in cold temps, alkaline barely work, but die quickly in the cold.
And since I use my headlamps a lot more in cold weather for reading and hiking in the dark, I am forced to use standard AA lithium's.
They don't pollute the way other batteries do, contain less toxic substances.
Lithiums store their charge far longer than other batteries, last far longer, work well in the cold and are much lighter.
