I have experienced this with green lasers bought from China. 5mW to 30mW pen types.
If the batteries are left in overnight, the next day the laser does not work well (it is not as bright as usual).
Also, if the laser is turned on for 1 minute, the laser loses power after 1 minute.
Is this a heating issue or something? Only happens with the green lasers I have bought.
Very confused by the power loss simply by leaving the batteries in over night.
Thanks.
