Light Brick 2 x 3 - How long can it work? And can it be damaged?

[Kalais]

Hello, was wondering how long can part 54930c02 be turned on before battery goes down?

Also it will not be damaged if I turn it on for like 3-4 hours?

I do not have one of these, but I do have another question to add: Do those bricks have a replaceble battery?

I'm not sure about the first two questions, but as for the battery it is replaceable. There is a screw on the bottom of the brick that can be removed to open it up and replace the two LR41 batteries in it.

As it's quite a simple circuit with two batteries, some conductive metal, some of it bend to make a contact, and a LED, I can't see any real potential for damage. I have one where the batteries have died, but I have no idea how long it had been on.

Okay, lets put some minds at ease.

the leds used in modern 2x3 light bricks should have a burning lifetime of 10k+ hours.  damaging an LED, usually is the result of voltage surges (having blown up a few myself) and the light brick doesn't have the ability to do that.

frankly the LR41 button cells will die on you most often as a LR41 cell has only a nominal 30 mah capacity. without doing the math, the cell pair should last for a day or so continous.  the led run like that a long time.
