Battery for light brick

Jasiek

Hi,
I've just got a red 2x3x1,1/3 light brick with no battery inside. I believe this is a brick 54869: http://brickset.com/parts/design-54869. Or 98782: http://brickset.com/parts/design-98782. Used in e.g. Sonic Boom or Sunshine Home.
Does anybody know or is able to check what kind of battery does it have?
Many thanks!
Jan

@Jasiek, those bricks need two LR41 (1.5 V). Usually it is mentioned in the instructions, like on the bottom of page 4 for #31038

Thank you very much! I couldn't find it in online instructions - too tiny letters, I think ;)
Cheers!

And if you have fat fingers, a pair of tweezers can help too.
