Tag Leonardo iMU Storage Consideration

The tags are equipped with Lithium polymer batteries. Over-discharging can damage the Tag's battery permanently. It should be noted that the battery would be at an over-discharged state by its self-discharge in case the cell is not used for a longer period. To prevent over-discharging, the tag’s battery shall be charged periodically to maintain between 3.7V and 4.1V.

👉🏻 We recommend storage the tags in a power-off state. Tag should be charged before storing it in the warehouse.

⚠️Once the Li-pol battery voltage drops below 3.0V, it is necessary to arrange the recharging within days. Otherwise, battery self-discharge can further deplete the battery, and it may not be rechargeable again.

Storage of tags in the power-off state

During long-term storage, it is recommended to check the condition of the batteries every 3 months, and if the voltage drops below 3.6V, the tags should be recharged.

Storage of tags in the power-on state

Only the tags with enabled Sleep mode can be stored in a power-on state. Otherwise, the tags would still transmit the UWB blinks, and the batteries would discharge quickly.

During long-term storage in the power-on state, the battery level should be checked every 2 months, and if the voltage drops below 3.6V, the tags should be recharged. If the tags in the warehouse are exposed to any vibrations that could wake them up from a sleep mode, the check period should be shortened.

Storage with Sleeping mode

Be sure the place where the tag with sleeping mode enabled is outside the busy area where frequent vibrations may occur. The vibration can wake up the tag, which then starts transmitting UWB blinks
