I need to know the difference

[Crazyk187]

Can anyone tell me the difference between these 2 batteries?? The blue 1 is from a chinese laser I bought..... I put it in my 405 and it worked for like 10 seconds and now I have nothing..... did I fry my driver or the diode??..... I don't know how to tell if it is protected battery or unprotected battery and if that even matters??

Throw the blue cell away.
