CR2025 Battery,3V Lithium Coin Cell Battery for Compact Power Needs

Overview of CR2025 

CR2025 Battery are standard 3 Volt lithium batteries, commonly used in watches, cmos, car keys, electronic toys and calculators.

These coin-shaped batteries, also called button cells, are part of a family of small, round batteries commonly used in compact electronics.

The name CR2025 tells you about its size and type:

•  "CR"means it's a lithium manganese dioxide battery
•  "20"means it's 20mm in diameter
•  "25"means it's 2.5mm thick

It is part of the broader button cell battery sizes family and a go-to option for electronics engineers and product developers.

We stock many different brands of cr5 battery from the world's leading manufacturers.

RFQ –   CR2025 and CR2032 Batteries

Q1: Can I use a CR2025 battery instead of a CR2032?

hey might look similar, but they're not exactly the same.
Both have the same diameter (20mm), but the CR2032 is thicker (3.2mm vs. 2.5mm for the CR2025).
If your device is designed for a CR2032, using a CR2025 could lead to a loose fit, poor contact, or shorter run time. It might work in some cases, but it's not ideal.
Quick Tip:
If you're in a pinch and only have a CR2025, you can fold a small piece of aluminum foil and place it on the positive side (+) to make up for the 0.7mm gap. This helps ensure contact.
However, this is only a temporary solution and not recommended for long-term use.

Q2: What are the safety tips when using CR2032 or CR2025 batteries?

Store CR2025 and CR2032 batteries in a cool, dry place, away from heat and moisture. Never try to recharge them, as they can overheat or leak. Avoid short circuits by keeping the battery ends away from metal. Do not mix old and new batteries or different brands. Keep the battery safe from physical damage, and check for leaks or swelling regularly. Keep these batteries out of reach of children and pets to avoid choking hazards. Always dispose of used batteries properly by recycling them through local programs.

Q3：How long a CR2025 battery will last?

A CR2025 battery has a shelf life of up to 10 years if not damaged and in storage in a cool, dry place. That means its battery remains in good shape, even after spending years in storage.

In typical use, its runtime depends on the device:

• In a car key fob, 3 to 4 years.minLength of 3 characters!
• If it is used in a tracking device or a remote then it will last approximately 1 year
• In a watch or calculator, that period may span 2 to 5 years

CR2025 is slightly lower power than CR2032, so it may not last quite as long in battery-hungry devices.

Q4:What uses a CR2025 battery?

this kind of cr2025 cell can be used in different small devices and space is limited. Common uses include:Car key fobs,Watches,Calculators,Motherboards (for use as CMOS memory),Remote controls,Toys and games,Garage door openers,Pedometers and Fitness Trackers,LED lights,Small medical devices. It is a favored alternative when the device requires a thin, flat battery.
