Battery life

Battery life depends on usage, but as a rough guide:

  • Standby: ~12 months with 8 × quality alkaline cells
  • Active (10 unlocks/day): ~9 – 10 months
  • Low-battery warning: the Battery lamp (red) lights up on the outer body
tip

When the low-battery indicator appears, replace all 8 batteries at once with a matching fresh set. Do not mix brands or chemistries.
