Questions about this item

How do I install the LIR2032 3.6 V battery and which way does the positive side face?

Slide the cell into the holder with the marked positive side up; the flat 20 mm diameter face is the positive terminal, and the 3.2 mm thickness fits the standard 2032 cavity.

When will the 40 mAh lithium-ion cell need replacing?

Rechargeable lithium-ion chemistry typically delivers several hundred charge cycles; replace the 3.1 g cell once run-time in your device falls below half of the original 40 mAh capacity.
