CR2025 lithium coin cells — five-pack

This pack contains five 3 V lithium button cells sized to the CR2025 standard. They power small everyday devices such as car key fobs, glucose monitors, pedometers, watches and calculators. Each cell measures 20 mm by 20 mm by 2.5 mm and is supplied new in retail packaging. The chemistry is non-rechargeable lithium metal.

Wide temperature range and long shelf life

The cells operate from minus 4 °F up to 140 °F, so they remain reliable in cold mornings and hot interiors. An anti-leak design and low self-discharge chemistry give up to 10 years of storage life when kept properly. They replace common equivalents including ECR2025, BR2025, LM2025, DL2025 and KT-CR2025.

Capacity and device limits

A single CR2025 suits low-drain electronics that draw only microamps to a few milliamps. It will not sustain high-current loads such as bright LEDs, motors or wireless transmitters for long. Devices requiring a thicker 2032 cell or a rechargeable chemistry cannot use this size. The five-pack covers multiple fobs or sensors but offers no reserve for power-hungry applications.

Questions about this item

How many cells come in the pack and is that enough for my key fob?

The pack contains five CR2025 lithium coin cells. A typical key fob uses one cell, so the pack covers multiple replacements or spares for other devices.

The listing says 3 V — what does that deliver in a real device?

Each cell supplies a steady 3 V output with lithium chemistry, maintaining voltage across a temperature range of -4 °F to 140 °F for reliable operation in fobs, glucose monitors and pedometers.

Does the CR2025 size match the 2025, ECR2025 or DL2025 codes on my device?

Yes. The cell measures 20 x 20 x 2.5 mm and fits any device specifying 2025, ECR2025, BR2025, LM2025, 5003LC, DL2025, CR2025, KT-CR2025, 280-205 or SB-T14.
