Panasonic CR1632 3V Lithium Coin Cell Battery - Single Pack

The Panasonic CR1632 is a 3V lithium coin cell battery measuring 16mm in diameter and 3.2mm in height. It delivers 3V nominal voltage across a stable discharge curve, designed for low-drain devices including watches, calculators, car key fobs, fitness trackers and medical equipment where space constraints require a compact power source.

The lithium chemistry provides a 10-year shelf life from manufacture when stored at room temperature, allowing the battery to be kept as a spare without significant capacity loss over time. This makes the CR1632 suitable for emergency backup applications and infrequently-used devices where the battery may sit dormant for months between uses. The stable voltage output maintains consistent device function until near end-of-life rather than gradual performance degradation.

Operating temperature range runs from -20°C to +65°C, covering outdoor applications in cold climates and devices mounted in vehicle interiors subject to summer heat. The coin form factor slides into standard CR1632 battery holders used across consumer electronics, with the lithium composition providing higher energy density than alkaline alternatives of the same size. Each battery ships in blister packaging with child-safety features and mercury-free construction.

What devices use a CR1632 battery?

The CR1632 powers watches, calculators, car key fobs, bike computers, fitness trackers, glucose monitors and other small electronics requiring 3V power in a thin coin-cell format. The 16mm diameter and 3.2mm height fit standard CR1632 battery holders found across consumer devices.

How long does the battery last in storage?

Panasonic rates the CR1632 with a 10-year shelf life when stored at room temperature in original packaging. This allows batteries to be kept as spares without significant capacity loss, making them suitable for emergency devices or infrequently-used equipment.

Can the CR1632 be used in extreme temperatures?

Yes. The operating temperature range of -20°C to +65°C covers outdoor winter use and devices left in vehicles during summer. The lithium chemistry maintains stable voltage output across this temperature range, unlike alkaline cells which lose capacity in cold conditions.

Is this battery rechargeable?

No. The CR1632 is a primary (single-use) lithium cell and cannot be recharged. Attempting to recharge a non-rechargeable lithium battery can cause leakage or rupture. Dispose of used batteries at designated recycling points.
