I got one of those cheap ones that you got to shake. As soon as I got
it home I noticed inside the semi-clear case that there is a disk
battery inside. This thing comes apart easily. I removed the battery
and found that I would have to shake it continually to keep the led
glowing. The battery is a lithium disk, similar to ones used in a
watch but about the size of a nickle. As far as I know, they are not
rechargable. Thus the shake generator is of little use at all. The
batteries are around $2, the flashlight was $5, so I'll likely replace
the battery when it dies, but in realitym the whole concept is just a
joke. About the only time the shaker is doing anything is while
shaking it, and what good is that when trying to see in the dark.
