button battery 2025

The common types of button batteries are as follows:

1. Button batteries generally have two types: rechargeable and non-rechargeable. The rechargeable ones include 3.6V rechargeable lithium-ion button batteries (LIR series), 3V rechargeable lithium-ion button batteries (ML or VL series) ; Non-charging includes 3V lithium-manganese button batteries (CR series) and 1.5V alkaline zinc-manganese button batteries (LR and SR series).

2. The more common button batteries are AG3, AG30, AG33 batteries used in toys and gifts, and batteries on computer motherboards. The model is CR2032 for CR2025 in electronic dictionaries, and CR2016 or SR44, SR626 for electronic watches. wait.

3. The English letter in front of the model name of the button battery indicates the type of the battery, the number indicates the size, the first two numbers indicate the diameter, and the last two numbers indicate the thickness.

Common typical models are: 6F22(9V), 4F22(6V), 15F20(22.5V), 10A(9V), 11A(6V), 23A(12V), 25A(9V), 26A(6V), 27A(12V) ), 476A(6V), 120H7D(8.4V), 2X625A(3V) and so on.

What is the difference between button battery 2025 and 2032

1. The thickness of the battery is different: the thickness of CR2032 is 3.2mm, and the thickness of CR2025 is 2.5mm; different thicknesses are suitable for different models.

2. Different capacity: CR2032 has 50-80mAh more capacity than CR2025. Due to its large capacity, it is mostly used in electrical appliances with higher power.

3. The discharge current is different: CR2032 can withstand a maximum continuous current of 20mA, while CR2025 usually can only withstand a discharge current of 10mA, so when choosing a model, you must match it according to the actual current used by your product.
