What’s the relationship between CR1616 and CR1632?

Lithium CR1616 is a button /coin cell battery, featuring a 16 mm (0.63 inches) diameter and 1.6 mm height  (0.06 inches) - hence the '1616' as a common part of most labels. Common CR1616 battery weighs in the 1.1 and 1.3 grams range. The CR1616 batteries can be used for laser pointers, insulin pumps, heart rate monitors, toys, watches, cameras, calculators, car security alarms, keyless car remotes, organizers, and computer equipment. They also work in extreme temperatures and hold power for up to eight years in storage.

The following is the 2D-Model of CR1616.

The CR1632 battery provides a consistent voltage supply while remaining lightweight enough for travel and storage. These batteries were designed with performance in mind, providing you with the long-lasting power you need to keep all of your gadgets running. These batteries can be found in a variety of gadgets, including calculators, cameras, heart rate monitors, and even toys, and can operate in a wide range of temperatures. The CR1632 battery has a long shelf life and a large storage capacity, making it a reliable power source for your tiny electrical gadgets.

The following is the 2D-Model of CR1632.

CR1616 Features

• The high energy density  (3V) with a flat and low self-discharge.

• Design, safety, manufacturing, and qualification follow Procell’s stringent battery standards, which incorporate parts of the ANSI and IEC battery standards.

• Economically packaged.

• Child secure packaging: tamper-proof pack with a double blister so that it is impossible for a child  to open without scissors 

• Operating temperatures  from -20℃～+70℃

• Good pulse capability

• High discharge  characteristics

• Stable voltage level  during discharge 

• Long-term reliability 

CR1632 Features

• Non-Rechargeable Lithium coin cell Battery

• Nominal Voltage: 3V

• Battery Capacity: 130mAh

• Continuous drain current: 0.19mA

• Peak drain current: 6.8mA

• Weight: 1.8 grams

According to the specifications, the two batteries have the same nominal voltage, which is 3V. 

A CR1616 battery is 1.6mm high, whereas a CR1632 battery is 3.2mm high. Remember, in respect of various works, the height of a battery also matters. It’s a crucial part of cell composition.

You may have heard of the use of CR1616 in Honda and Lexus key fobs. Aside from these, it can also be used in other car brands. The CR1616 is a reliable battery that can be used in a variety of electrical gadgets. These are as follows: 

• Glucometers

• Heart rate monitors

• Toys

• Computer backup equipment

On the contrary, CR1632 batteries are ideal for different helpful stuff. 

• Small PDA devices

• Wireless doorbell for house

• Electronic Toys

• Portable electronics

• Digital thermometers

• Digital altimeter

• Cyclocomputers

• Heart rate monitors

You won’t see any expiration date of a 1616 battery. However, it has an average lifespan. Generally, this type of battery lasts for approximately 5-10 years.  

On the contrary, a battery CR1632 usually lasts for around 7 to 10 years.

A single battery has several variations, each with its own label. Anyway, here are some popular CR1616 comparable battery labels:

• DL1616

• BR1616

• ECR1616

• 280-209

• GPCR1616

• LiR1616

• KCR1616

• 5021LC  

Now let us see the common labels for CR1632 equivalent batteries! Here they are:

DL1632, ECR1632

Same diameters

CR1616: 16mm 

CR1632: 16mm

Different thickness

CR1616: 1.6mm

CR1632:  3.2mm

Obviously, they are not the same size. CR1616 is 1.6mm in thickness while CR1632 is 3.2mm in thickness. And the thickness of TWO pieces of CR1616 equals ONE CR1632. Can I use 2 pieces of CR1616 to replace ONE CR1632? No. The two batteries are added together to form a series. Consequently, the current-voltage is 3+3=6V. 6V is bigger than 3V. If forcibly used, electronic products will be destroyed.
