Panasonic CR2025 3V Lithium Coin Cell Batteries - 6 Pack

The Panasonic CR2025 is a 3V lithium coin cell battery measuring 20mm in diameter and 2.5mm thick, supplied in a blister pack of six cells. Each battery uses lithium manganese dioxide chemistry to deliver stable voltage across a wide operating temperature range from -20°C to +65°C, making them suitable for devices used both indoors and in vehicle environments.

Designed for low-drain devices that require occasional bursts of power rather than continuous discharge, CR2025 batteries are commonly fitted in car key fobs, remote controls, fitness trackers, bathroom scales, digital thermometers, calculators, and small LED lights. The 20mm diameter and 2.5mm height make them one of the thinner coin cells in common use, fitting battery compartments where space is limited. Each cell carries a nominal capacity of approximately 165mAh, though actual runtime depends on the device's power draw.

Panasonic rates these batteries with a shelf life of up to 10 years when stored at room temperature in the original packaging, which means they can be kept as spares without losing significant charge. The lithium chemistry retains voltage better than alkaline alternatives in cold conditions and maintains consistent output until the cell is nearly depleted, avoiding the gradual voltage fade that affects some other battery types. The six-pack format suits households or workplaces replacing batteries across multiple devices.

CR2025 batteries are also known under alternative manufacturer codes including SB-T14, 280-205, DL2025, ECR2025, and BR2025, though slight performance differences may exist between brands. The Panasonic variant uses the company's Cell Power Lithium technology, which refers to their manufacturing process for maintaining internal resistance and extending usable life under intermittent discharge patterns typical of remote controls and key fobs.

What devices use CR2025 batteries?

CR2025 batteries are commonly used in car key fobs, remote controls, fitness trackers, bathroom scales, digital thermometers, calculators, small LED torches, and glucose meters. Any device requiring a 3V coin cell with a 20mm diameter and 2.5mm thickness will accept a CR2025.

How long do CR2025 batteries last?

Shelf life is up to 10 years when stored in the original packaging at room temperature. Once fitted in a device, runtime depends on power draw. In a typical car key fob used several times daily, a CR2025 may last 1-2 years. In a rarely-used remote control, it may last 3-5 years.

Can I use a CR2032 instead of a CR2025?

No. While both are 20mm in diameter and deliver 3V, the CR2032 is 3.2mm thick compared to the CR2025's 2.5mm. A CR2032 will not fit in a battery compartment designed for a CR2025 because it is too thick.

Are these batteriesrechargeable?

No. CR2025 lithium coin cells are single-use primary batteries and must not be recharged. Attempting to recharge them can cause leakage, overheating or rupture. Use only in devices designed for non-rechargeable coin cells.
