CR2025 battery Dimensions

CR2025 battery dimensions

CR2025 vs CR2032

Battery	Anode	Cathode	Maximum voltage	Capacity	Nominal diameter	Thickness
CR2025	Lithium	Manganese Dioxide	3.7V	170mAh	20.0mm	2.5mm
CR2032	Lithium	Manganese Dioxide	3.7V	220mAh	20.0mm	3.2mm

Thickness

The main difference is thickness; the CR2025 battery is 2.5mm thick, and the CR2032 battery is 3.2mm thick. The CR2032 battery can be used for snugly battery rooms.

Capacity

The CR2032 battery has a high thickness and provides a high capacity of 220mAh, and the CR2025 has 170mAh. So CR2032 works longer. Such as in high-drain applications, the CR2025 works for two to three years, and the CR2032 works for 3 to 4 years.

The high mAH capacity also has an effect on working life, like CR2032 has a longer working life than CR2025.

Weight

The CR2032 battery has a weight of 3 grams, and the CR2025 weight is 2.6 grams. If your device is not weight constrained, then we can replace CR2025 with CR2032. .

Durability

The high capacity for a battery comes with a higher mAh rating, and high mAh are provided for a longer working life. The battery with a capacity rating of 100mAh will retain current 100mA for one hour.

The CR2032 battery can increase its rating to 240mAh, and the CR2025 battery rating is 170mAh.

Similarities Between CR2032 and CR2025 Batteries

The cutoff voltage for these batteries is three volts.
Both have a 20mm diameter, and both are lithium-ion batteries with a temperature range of -30 to 60 degrees Celsius.
Both are used for the same devices energizing.
Both have a constant working life for the same storage conditions, and they have longer equivalent discharge features, which is a 1% self-discharge rate.

Factors to Consider for Using CR2025 Instead of CR2032

Voltage

There is a certain working voltage value for any device. So the battery must have the required voltage for that device to function normally. Replacing the CR2025 with the CR2032 for maintaining voltage is important, and both batteries provide three volts.

Current

The device has a certain current drawn for working conditions as a voltage value. The CR2025 and CR2032 both have 0.2 mA current, so we can replace them.

How Long Do CR2025 Batteries Last?

CR2025 batteries are used for car key fobs with a working life of about 3 to 4 years. In IoT, tracking devices are used for one year.

CR2025 Discharge Features

The CR2025 battery is used for portable applications. The working life of a battery is based on working temperature, discharge current, and dynamic loads.

If there is 20 mA current for 20 degrees. For these conditions, the mAh capacity of the battery is 163 mAh. So if we draw current 163 mA, then the battery will work for one hour, and if there is 81.5 mA current, the battery will work for two hours.

If the battery uses 20 mA, it will work for 8.15 hours.
