Coin cell lithium battery Philips CR2025 4-pack (CR2025P4-01B)

Philips CR2025 is a lithium coin cell battery sold as a 4-pack. Each cell provides a nominal voltage of 3V and is designed for compact, low-drain electronics such as key fobs, wristwatches, calculators, small medical devices, and remote controls. The pack format makes it convenient for replacing exhausted CR2025 cells and for keeping spares on hand for devices that require long shelf life and stable voltage output.

Advantages

The Philips CR2025 delivers consistent 3V output over its useful life, offering stable performance in low-drain applications. Lithium chemistry provides a long shelf life and good performance across a range of temperatures. The 4-pack presentation gives multiple replacements in a single purchase and reduces the need to buy individual cells repeatedly. The cells are compact and lightweight, fitting standard CR2025 compartments without modification.

Suitable for

• Car key fobs and remote keyless entry systems
• Wristwatches and small electronic timepieces
• Calculators and small handheld electronics
• Medical devices requiring low-drain, long-life cells (verify device compatibility)
• TV, audio and other household remote controls

When it may not be suitable

The CR2025 is intended for low-drain devices; it may not provide sufficient current for high-drain electronics or devices that demand sustained high power output. It is not a rechargeable cell and should not be used in applications designed for rechargeable batteries. Always verify the device manufacturer's recommendations for battery type and size before replacement.

Key specifications

• Nominal voltage: 3 V
• Cell type: Lithium coin cell
• Size designation: CR2025 standard dimensions (approx. 20 mm diameter, 2.5 mm thickness)
• Pack quantity: 4 cells per pack
• Typical use: low-drain, long shelf-life applications

How to use

Before installing a new CR2025 cell, switch off the device if possible and check the polarity marking in the battery compartment. Insert the cell with the correct orientation, ensuring it seats fully and the contacts are clean. After replacement, verify device operation. Dispose of used lithium coin cells according to local regulations or recycling programs; do not incinerate or expose to fire. Keep spare cells in original packaging until use to preserve shelf life.

What to consider before purchase

• Confirm that the device requires CR2025 size and 3V lithium chemistry
• Check device polarity and compartment access for safe replacement
• Consider storage conditions—cool, dry place to maximize shelf life
• Verify local disposal or recycling options for button cells

Usage recommendations

For reliable long-term performance, store Philips CR2025 cells in a cool, dry environment and use them before the manufacturer’s recommended expiry date. Replace all batteries in multi-cell devices at the same time and avoid mixing old and new cells to prevent uneven discharge and potential leakage issues.
