How log do the batteries last ?
The sample batteries included at purchase are for demo purposes only and don't laast very long. Good alkaline batteries should last several weeks with standard intermittant use. The wide task light uses more power than the flashlight.
How can I install the batteries in litezall 400 lumens
Unscrew the cap at the bottom of the light and remove the batteries. Insert 3 new AA (alkaline strongly recommended) batteries, positive end first. Replace the cap.
