I have heaps of these in the yard, and as always, they tend to die after a while.They are the stand alone/ cheapo battery type.

Naturally, you only get what you pay for I guess, but why do they not seem to last long, and can they be refreshed.

Seems odd that we buy these things to avoid electricity usage, and probably burn tons of carbon disposing of all the dead one's too?

My bin seems to like em!!
