The difference is as follows:
1. Different sizes
The numbers behind CR represent the battery size. The first two are in diameter, and the latter two indicate thickness.
2032 CR Button Cell = 20.0*3.2 mm
2025 CR Button Cell = 20.0*2.5 mm
2. Different capacity
2025 is thinner than 2032, so the capacity is less, and the service life is shorter. CR2032 and CR2025 are 3V lithium manganese butt batteries. The voltage of the two is the same.
3. Disted current
CR2032 can withstand a maximum continuous current of 20mA. In contrast, CR2025 usually can only withstand 10mA discharge current, so when selecting the model, it is necessary to match according to the actual current of your product.
Extended information:
The button battery model can be classified based on a single standard, such as structure, voltage, and dimensions, and composite buttons can be classified. Practical button lithium batteries are generally marked by structure and shape size.
The button battery can be divided into two types: charging and non-filled. Standard charging butt batteries include the 3.6V LIR series and 3V ML series, and LV series. The non-charging button battery includes 3V CR series, 1.5V LR series, and 1.55V SR series.
The button battery model consists of English letters and numbers. The English letters in the front represent the nature of chemical power, and the four Arabic numerals of the suffix represent the battery size.
The buttons are small in shape and are generally used in the reserve power of electronic products, such as computer motherboards, electronic watches, electronic dictionaries, electronic scales, calculators, etc., with diameters ranging from 4.8mm to 30mm and 1.0mm to 7.7mm.
