What is a CR2032 battery? 

A CR2032 battery is a non-rechargeable (primary) lithium coin or “button” cell battery that is 20mm diameter x 3.2mm thickness. The CR2032 battery has a voltage of 3 volts and a capacity of up to 240mAh, depending on manufacturer specifications. The CR2032 is the most common lithium coin cell battery currently used. Commercial uses of the CR2032 battery range from car key fobs and motherboards to security system pannels and weapons sighting systems. The CR2032 can also be fitted with connection tabs that allow the battery to be fitted in almost any position needed. The compact size but relatively high capacity, service life, and consistant discharge make the CR2032 battery an ideal choice for a wide variety of applications. 

The CR2032 battery is also known as 2032, 5004LC, AWI L14, BR2032, BR2332, CR2032, DL2032, EA2032C, ECR2032, L2032, LF1/2V, LM2032, RFA-35, and Seiko SB-T15.

How Long Do a CR2032 Batteries Last?

Battery storage life can depend on a variety of factors including material quality, storage conditions, storage time, humidity, physical damage, or temperature. Ideally you would want a battery made of high quality materials, stored in a climate controlled and dry area, with no physical damage. Energizer claims that their lithium coin cell batteries have up to 10 years of shelf life when properly stored. As far as service life this will depend greatly on the application. A CR2032 battery in a car key fob may last up to 4-5 years before needing replacement as the use of the battery is very intermittent. A more active device such as the new Apple Air Tag which allows constant tracking of objects will only last about a year.

What Uses a CR2032 Battery?

The CR2032 battery is used in a wide variety of devices and applications including computer motherboards, car key fobs, watches, calculators, PDAs, electronic organizers, garage door openers, toys, games, door chimes, pet collars, LED lights, sporting goods, pedometers, calorie counters, stopwatches and medical devices.

What is a CR2025 battery? 

A CR2025 battery is 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 slighlty shorter service life than a CR2032 when used in similar applications.

 The CR2025 battery is also known as 280-205, 5003LC, BR2025, DL2025, ECR2025, and SB-T14, AWI L12, Citizen 280-205, Duracell DL2025, ElectroChem 3B980, Energizer ECR2025, Eveready CR2025, Fuji CR2025, I.E.C. CR2025, Kodak KCR2025, Maxell CR2025, NEDA 5003LC, Panasonic CR2025, RadioShack CS0155, RadioShack CS1005, RadioShack UBATL0006TAZZ, Rayovac KECR2025, Saft LM2025, Sanyo CR2025, Seiko SBT14, Sony CR2025, Toshiba CR2025, Varta CR2025, and 2025.

Energizer claims that their lithium coin cell batteries have up to 10 years of shelf life when properly stored. As far as service life this will depend greatly on the application. A CR2025 battery in a car key fob may last up to 3-4 years before needing replacement as the use of the battery is very intermittent. A more active device such as an IoT tracking device, which allows real-time, tracking of objects will only last about a year. This slightly shorter service life can be attributed to smaller capacity of the CR2025 battery.

What Uses a CR2025 Battery?

Similar to the CR2032 battery the CR2025 battery is used in a wide variety of devices and applications including computer motherboards, car key fobs, watches, calculators, PDAs, electronic organizers, garage door openers, toys, games, door chimes, pet collars, LED lights, sporting goods, pedometers, calorie counters, stopwatches and medical devices. Like we previously mentioned, the CR2025 battery is slightly better suited than the CR2032 to be used in devices which have limited mounting space in the battery compartment.

What are the similarities between CR2032 and CR2025 batteries? 

The CR2025 and CR2032 are both 3-volt lithium coin or button cells that measure 20mm in diameter. In terms of technology, both CR2025 and CR2032 batteries have the same voltage, chemistry, and diameter. Both batteries can power small devices like calculators, computer motherboards, fitness appliances, laser pens, POS systems, security devices, sensors, smart carport keyless entry devices, wrist watches, and various medical devices such as clinical thermometers, glucose monitors, heart pacemakers, and tensiometers. Both the CR2025 and CR2032 batteries from the same manufacturer will have the same shelf-life if stored in similar conditions. 

  Most major battery brands like Duracell, [ZEUS](https://www.bettlink.com/manufacturer/zeus-battery-products) Battery Products, [Panasonic](https://www.bettlink.com/manufacturer/panasonic), Philips, Maxell, Murata (formerly [Sony](https://www.bettlink.com/manufacturer/murata-electronics)), Renata, and others carry both the CR2025 and CR2032 batteries in their product catalogs as they are two of the most widely used batteries worldwide.

What’s the difference between CR2032 and CR2025 batteries? 

The obvious difference between the two battery types would be thickness. The CR2032 is 3.2mm thick while the CR2025 is 2.5mm thick. Because the CR2032 is 0.7mm thicker than the CR2025, it has a higher capacity (mAh) to deliver current to the load. A standard CR2032 can nominally deliver 225mAh while the average CR2025 can nominally only deliver 160mAh. Due to the smaller capacity, the thinner battery may not last as long and may need to be replaced sooner.
