Please use only genuine alkaline batteries.
Do not use IKEA or Daiso batteries.
The light stick requires high output; if battery level falls below 80%, it may not function properly.
During concerts, batteries drain quickly. For best performance, always use new batteries for each concert.
When storing the light stick, remove all batteries completely. If batteries remain inside, power may drain even when not in use, and the light stick may be damaged.
Always use brand-new batteries when installing.
Insert batteries in the correct direction:
Spring side = Negative (-)
Insert the socket correctly:
Raised part = Upward direction
