CR2025 Battery: Features, Pinout, and Datasheet

The CR2025 battery is a non-rechargeable (primary) lithium coin or “button” cell that is 20mm diameter x 2.5mm thickness. The CR2025 battery has a high voltage of 3V, a capacity of up to 170mAh, depending on manufacturer specifications. 

The CR2025 battery is an extremely common lithium coin cell battery and is used in similar amounts and in similar applications as the CR2032.  The CR2025 is slightly better suited for use in products that have less available mounting space than those that would use a CR2032. 

On the other hand, the lower capacity (mAh) of the CR2025 will give a slightly shorter service life than a CR2032 when used in similar applications.

• Lightweight, High Voltage And High Energy Density
The battery voltage is 3V, almost double that of normal alkaline or manganese batteries. This means that the number of batteries required for equipment can be halved for maximum space-saving and weight reduction.

• Excellent Discharge Characteristics
Voltage characteristics remain stable even for a long period of discharge, greatly improving the reliability of equipment that uses the battery. Such equipment is also maintenance-free (battery replacement is seldom required).

• Excellent Leakage Resistance
The newly developed battery construction and electrolyte ensure maximum leakage resistance over a long span of time.

• Excellent Long-Term Reliability
Carefully selected active materials are used for the active material as well as for the electrolyte. These materials are sealed by Murata's innovative technology to minimize battery self-discharge. The annual self-discharge rate at room temperature and normal humidity is less than 1% of the nominal capacity.

• UL Approved Parts
Murata's Coin Manganese Dioxide Lithium Batteries are approved by UL. (UL1642 File No. MH12566)

• RoHS  Directive / European Directives
This product does not contain Mercury(Hg), Cadmium(Cd), nor Lead(Pb), and conforms to EC regulation values. (Directive 2006/66/EC, 2013/56/EU)
The Battery pack is excluded from RoHS directive (DIRECTIVE 2011/65/EU OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 8 June 2011 on the restriction of the use of certain hazardous substances in electrical and electronic equipment).
