Isn’t it frustrating when you insert a button cell battery into a gadget only to get an error message?

Don’t worry. You aren’t alone. Since several battery types look similar, most people can’t tell them apart.
It’s also challenging to remember the battery names. Battery CR2025 vs. CR2032—they’re long, and they’re confusing.

There’s also a clear scarcity of information on 3V button cells, which doesn’t help at all.

A CR2025 battery is a generic designation for a non-rechargeable (primary) lithium coin battery. It’s got a cutoff voltage of 3 Volts.

The CR2025 coin battery model has a battery storage life of 10 years.

These popular CR2025 batteries have a very low self-discharge, making them the most preferred alternatives for traditional batteries.

A CR2025 flex PCB is a flexible printed circuit board designed to hold a CR2025 coin cell battery.
This type of PCB is commonly used in small electronic devices that require a compact and lightweight power source.

The flexible design of the PCB allows it to be bent or twisted to fit into tight spaces or conform to the shape of the device.
The CR2025 battery is soldered onto the PCB and provides a reliable power source for the device.

The flex PCB is typically made of thin, flexible materials such as polyimide or polyester, and can be customized to fit the specific needs of the device.

types of cr2025 flex pcb

There are several types of CR2025 flex PCBs available, including:

1. Single-sided flex PCB: This type of PCB has a conductive layer on one side and an insulating layer on the other.
It is commonly used in low-cost and low-complexity applications.

2. Double-sided flex PCB: This type of PCB has conductive layers on both sides,
which allows for more complex circuit designs. It is commonly used in more advanced applications.

3. Multi-layer flex PCB: This type of PCB has multiple conductive layers separated by insulating layers.
It is commonly used in high-density and high-performance applications.

4. Rigid-flex PCB: This type of PCB combines both rigid and flexible materials to create a hybrid board.
It is commonly used in applications where both flexibility and rigidity are required.

5. Sculptured flex PCB: This type of PCB has a three-dimensional shape, which allows it to fit into unique and irregularly shaped devices.
It is commonly used in medical and aerospace applications.
