  • Two-pack delivers 3.1 g lightweight cells for portable builds

LIR2032 3.6 V rechargeable button cells

These lithium-ion button cells deliver 3.6 V nominal voltage in the standard 2032 footprint. Each cell stores 40 mAh and weighs 3.1 g. The two-pack suits devices that accept the higher voltage of rechargeable lithium-ion chemistry.

Replaces hundreds of disposable CR2032 cells

One LIR2032 can replace 200 primary CR2032 batteries, cutting waste and long-term cost. The jump is worth it only for equipment designed for 3.6 V operation; devices built for 3 V primaries may malfunction or be damaged.

Simple drop-in when voltage matches

Installation is a direct swap in any 2032 holder, measuring 20 mm by 3.2 mm. What usually goes wrong is inserting them into 3 V-only gear — always confirm the device supports 3.6 V before fitting.

Questions about this item

Will the 20 mm diameter LIR2032 fit the same holder as a CR2032?

Yes, the cell is the same 20 mm diameter and 3.2 mm height as a standard CR2032, so it drops into any CR2032 socket.

Is there a polarity tab or notch to watch for when inserting the 3.6 V cell?

The positive side is the flat face marked with the + symbol; insert that side toward the spring contact and the negative rim toward the case wall.

After roughly how many charge cycles will the 40 mAh capacity drop noticeably?

The lithium-ion chemistry has no memory effect and is rated for long service life, typically retaining usable capacity well beyond 200 full charge-discharge cycles.
