Introduction: What Are Coin/Button Cell Batteries?

Coin or button cell batteries get their name because they are small and round, looking like coins. These batteries are mostly made of lithium. That makes them different from bigger, tube-shaped batteries like the AA ones. Button cells are smaller. You often find them in watches, calculators, medical devices, and more. These button cells use lithium chemistry, so they have a steady nominal voltage and long battery life.

CR 2016 Battery Overview

The CR2016 lithium battery is a small lithium coin cell that you can find in many common gadgets. It has a nominal voltage of 3 volts. It offers about 90mAh of power, so you get good battery life for gadgets that do not use a lot of energy. This battery comes with a diameter of 20mm and a thickness of 1.6mm. The size makes it perfect for things like calculators or a CMOS memory backup.

CR 2032 Battery Overview

The CR2032 lithium battery stands out because of its special size. This lithium coin cell battery has a nominal voltage of 3 volts. It has a thickness of 3.2 mm and a diameter of 20 mm. The battery usually holds between 220 mAh and 240 mAh, so it can last a long time in many tools. You can find this lithium coin battery in medical devices, calculators, and different types of electronic gadgets.

CR2032 VS CR2016：Key Differences

Diameter, Thickness, and Weight Differences

The size of the CR2016 and CR2032 3V batteries plays a big part in how they work and where you can use them. Both of these batteries have a diameter of 20mm. But CR2016 is 1.6mm thick, while the CR2032 is twice as thick at 3.2mm. This thickness makes a strong difference in the battery compartment fitting in many devices. When you look at weight, CR2016 is lighter at 1.6g, and CR2032 is heavier at 3.1g.

Capacity and Lifespan

When you check battery capacity, the battery CR 2032 gives about 220mAh to 240mAh. The CR2016 only offers around 90mAh. This is a big difference and means that the CR2032 gives longer battery life. So, the CR2032 is better when you need it to work for a long time, as it holds more energy.

Both of these batteries are good when it comes to shelf life. If you store them in the right way, they can last between 7 to 10 years. The CR2016′s smaller capacity makes it best for low-power things. But if you need to power medium-use devices or need longer use, then the CR2032 is a better pick.

Application Suitability – When to Choose CR2032 or CR2016

The CR2016 or the CR2032 can both work for you, but it really depends on what your device needs. If your gadget needs less power and has a small battery compartment, the CR2016 is a good choice. It works well for:

• Calculators and remote controls.
• Watches and alarm systems.

The CR2032 is good for things that need more power or run for a longer time. You can use this one in:

• Medical devices and CMOS boards.
• Fitness trackers and memory cards.

When you pick between these lithium batteries, you should check if the thickness fits with your device’s battery compartment.

Electrical Characteristics – Discharge Curves, Pulse Current, and Temperature Range

Both CR2032 and CR2016 have steady discharge curves, which is important if you want a battery that works well for a long time. The CR2016 has a low pulse current. On the other hand, the CR2032 can handle higher pulse currents. So, it works well for devices that use more energy. Both of them can work in temperatures from -20°C to 70°C. This means they will run well in many different climates.

Cost and Availability – Budget Considerations for Bulk Purchases

The price is not the same for CR2016 and CR2032 button cells. The CR2016 usually costs less, and it has a shorter battery life. The CR2032 will cost a bit more, but the battery life is better. People use it when they want the item to work well for a long time.

You can find both of these button cells in electronics shops, supermarkets, or on online sites. If you use a lot of these batteries over time, it can be good to buy in bulk. This is a good idea for CR2032 coin cell batteries since you pay more at first, but the battery life is longer, so you do not have to replace them as often. Reliable brands like PKCell make these button cells, so you can trust that these batteries work as they should.

CR2032 and CR2016 Comparison Table

Are CR2032 and CR2016 Batteries Interchangeable?

Both CR2032 and CR2016 button batteries give the same nominal voltage of 3 volts. But there is a big difference in their thickness. The CR2032 is 3.2mm thick, so it will not fit in places made for the thinner CR2016, which is only 1.6mm thick. If you put a CR2016 where a CR2032 is needed, it will lose power faster and not work as long.

Sometimes, people stack two CR2016 batteries to try to act like one CR2032 battery. This may fit in the space, but it does not give a steady voltage. It is always better to use the right battery your device asks for. This helps stop it from breaking or having problems.

Similarities Between CR2032 and CR2016

CR2032 and CR2016 both use the same lithium-manganese inside them and have a round design. This helps them give a reliable nominal voltage of 3.0V. These two batteries are 20mm in diameter. They also work well in the same temperature range, from -20°C to 70°C.

These batteries have a cylinder shape and a metal-button look. Their shelf life can be up to 10 years for both the CR2032 and CR2016. This is good for people who need them for memory cards or many kinds of electronic gadgets.

FAQs for Engineers and Procurement Managers

Can I use a CR2032 for my device designed for CR2016?

Using a CR2032 in a device designed for a CR2016 is not advisable. While both batteries share the same nominal voltage of 3 volts, the significant difference in thickness means that a CR2032 will not fit into the compartment of devices meant for a CR2016.

What is the shelf life of CR2032 and CR2016 batteries?

The shelf life of CR2032 and CR2016 batteries is usually between 3 and 10 years. The time depends on how you store them. If you keep these batteries sealed and in a cool, dry place, they last longer. This way, you get good performance from them when you need to use the batteries.
