What’s the relationship between CR2032 and CR2016?

The CR2016 lithium coin cell is a primary lithium battery with a voltage of 3V. The CR2016 lithium coin cell is a 3V Lithium battery with a long shelf life for back up energy, great temperature resistance, and superior storage capacity. This lithium coin cell battery has a high energy density, durability, and stability, as well as long battery life in a variety of applications.

The CR2032 battery is a non-rechargeable (primary) battery that is very common today. It is a coin-cell battery that utilizes lithium chemistry. These batteries are used in a wide range of applications and are available from many retailers.

The duo of CR2016 and CR2032 batteries have the same diameter of 20mm. The first two numbers of the battery name ‘20’ stand for the diameter. 

Depth is the only visual difference between these 2016 and 2032 batteries. The CR2016 battery has 1.6mm and the CR2032 battery has 3.2mm. The last two numbers of the battery names such as ‘16’ and ‘32’ stand for their respective depth.

CR2016 Application

CR2016 power supplies have demonstrated their worth and are used more frequently than other power supplies with similar dimensions. The CR2016 battery is used in a wide variety of devices and applications including Watches, Calculators, PC notebooks, Electronic keys, Card-type radios, IC cards, Memory cards, Medical equipment, and CMOS memory backups.

CR2032 Application

The CR2032 battery is used in a wide variety of devices and applications including computer motherboards, car key fobs, watches, calculators, PDAs, electronic organizers, garage door openers, toys, games, door chimes, pet collars, LED lights, sporting goods, pedometers, calorie counters, stopwatches, and medical devices.

Each of the CR2016 and 2032 CMOS batteries works properly under the temperature range of 0°C to 60°C. But the range varies from battery to battery of different brands. If the operating temperature goes beyond the standard range, the battery will lose its capacity and the device will start malfunctioning or not work at all.

The weight of the CMOS batteries also varies with their depth. For CR2016, the weight is 2.3gram and for CR2032, the weight is 3.1gram.

The nominal voltage for both the 2032 and 2016 CMOS batteries is the same, which is 3V. Because of this shared feature, both of the batteries can act as a replacement for another one.

Capacity is one of the main differences between the CR2025 and CR2032 batteries. The 2032 CMOS battery offers more capacity which is 225 mAh. On the other hand, the 2016 CMOS battery capacity is only 90 mAh.

None of the 2032 and 2016 CMOS batteries are separately rechargeable. They only get charged via laptop while it is plugged in. 

CR2016 and CR2032 may vary in thickness, but they are identical in several ways.

They're both 3-volt versions, and none of them is rechargeable. However, it is important to remember that there are variations in ability. CR 2032 has a capacity of 240 mAh, while CR2016 has a capacity of just 90mAh. The CR2032 can provide 10 hours of use, while you only get about six hours from the CR2016, depending on the power you're using, of course.

Due to their equivalent voltage, there are several cases where CR2016 and CR2032 can be interchanged. However, the fact that they have different capacities and therefore different run times can cause problems. You will not get the power from the CR2016 that you will get from the CR2032, and some devices won't function at all.

Modern CR2016, BR2016, and LiR2016 batteries are made using no lead, cadmium, and similar heavy metals, but, they are nonetheless dangerous when swallowed.

With 20mm diameter, they are not easy to swallow, but just in case, keep them away from kids and pets. And if something like that happens, call emergency services right away.

Although they don't contain heavy elements, they can cause electrolytic reactions in the body that may be very harmful.

Fortunately, most CR2016 and similar batteries come in 'children safe' packages, making them generally inaccessible to children. IMHO, a very determined kid with scissors can open even such packages...
