The Ultimate Guide to Choosing a CR2016 Battery for Your Device

In this blog, we will equip you with everything you need to know about CR2016 batteries, ensuring you choose the right one for your device and replace it with ease.

What does CR2016 Mean?

The CR2016 Battery is a small yet powerful power source that keeps many common devices running. Despite its small size, this lithium coin battery can power everything from key fobs and auto remotes to calculators and medical gadgets.

What are CR2016 Batteries Used for?

Because of their small size and consistent performance, CR2016 batteries are extremely adaptable and can power a broad variety of devices. Here are some common examples:

• Key fobs and car remotes: Key fobs and car remotes use CR2016 batteries to deliver signals that unlock doors and trigger security measures.
• Calculators: Many compact calculators rely on CR2016 batteries for extended operation.
• Watches: Some digital watches and fitness trackers use CR2016 batteries.
• Hearing aids: Certain hearing aids use CR2016 batteries for inconspicuous and long-lasting functioning.
• Medical devices: Medical gadgets, such as glucose monitors and thermometers, may use CR2016 batteries.
• Gaming devices: Wireless controllers for certain game consoles may use CR2016 batteries.
• Motherboard memory backup: The CMOS battery on a computer motherboard frequently uses a CR2016 battery to save BIOS settings even when the machine is turned down.

How to Install CR2016 Battery?

The process of installing a CR2016 battery is uncomplicated. This is a general guide:

1. Identify the battery compartment: Locate the battery compartment on your smartphone. It may be secured with a screw or a simple latch. For more specific instructions, refer to your device's manual.
2. Open the Compartment: Open the chamber carefully, following the device's instructions.
3. Remove the Old Battery (if applicable): When changing an old battery, make note of the positive (+) and negative (-) indications. Remove the old battery gently using your fingertips or a nonmetallic instrument.
4. Orient the New Battery: The new CR2016 battery should have positive (+) and negative (-) markings. Match these markings to the symbols in the battery compartment.
5. Insert the New Battery: Carefully insert the new battery, following the positive and negative marks. Make sure it fits snugly in place.
6. Close the Compartment: Close the battery compartment securely according to the directions on the device.

Important Tips:

• Avoid contacting the positive and negative sides of the battery with bare hands for long durations. This may slightly degrade battery life. Use a tissue or plastic tool as needed.
• Batteries should never be disposed of in normal trash. Refer to your local recycling rules for safe disposal techniques.

How to Test a CR2016 Battery?

If your gadget is not performing as intended, it may be time to test the CR2016 battery. Here's a simple approach for utilizing a multimeter:

1. Set the Multimeter: Set your multimeter to DC voltage mode with a range of 1.5 to 3 volts (most multimeters include a 2-volt setting).
2. Touch the Probes: Carefully touch one multimeter probe to the battery's positive (+) terminal and the other to the negative (-) terminal.
3. Read the Voltage: The multimeter's voltage reading should be between about 3 volts (when fresh) and 2.8 volts (still usable). A reading substantially lower than 2.8 volts indicates that the battery has to be replaced.

How to Replace CR2016 Battery?

Replacing a CR2016 battery is comparable to the installation process described above.  Take these steps:

1. Turn off the device: Turn off your device before replacing the battery.
2. Locate and open the battery compartment: Locate the battery compartment and open it following the device's instructions.
3. Remove the old battery: Using your fingers or a nonmetallic instrument, carefully remove the old battery. Take note of the positive (+) and negative (-) markings for future reference when using the new battery.
4. Inspect the battery compartment: While the container is open, check it for signs of corrosion or damage. If you notice corrosion, carefully wipe the contacts with a dry cotton swab dipped in rubbing alcohol. Allow it to dry completely before inserting the new battery.
5. Insert the new battery: Find the positive (+) and negative (-) marks on the new CR2016 battery. Match these markings to the symbols in the battery compartment.
6. Secure the battery: Insert the new battery carefully, following the positive and negative marks, and making sure it fits snuggly.
7. Close the compartment: Close the battery compartment securely according to the directions on the device.
8. Power on the device: Turn on your device and see if it functions properly.

Are CR2016 and CR2032 Interchangeable?

CR2016 and CR2032 batteries perform similarly but differ significantly in size. Here's the breakdown:

• Size: The CR2032 is slightly larger than the CR2016. It is 20 mm in diameter (the same as CR2016) but 3.2 mm thick (compared to 1.6 mm for CR2016).
• Capacity: Because of its greater size, the CR2032 has a higher capacity (mAh) than the CR2016, allowing it to potentially store more power and last longer.

CR2016 Battery vs CR2032

Here's a breakdown of the key differences between CR2016 and CR2032 batteries:

Size:

• Both lithium coin batteries have a 20mm diameter.
• CR2016: Thinner to 1.6mm.
• CR2032: At 3.2mm, CR2032 is twice as thick as CR2016.

Capacity:

• CR2016: CR2016 has a lower capacity, often 75-90mAh.
• CR2032: Higher capacity, often 210mAh to 240mAh (almost double that of CR2016).

Applications:

• Due to the size difference:
  • CR2016: Suitable for products with low battery capacity, such as slim watches or compact remote controllers.
  • CR2032: Can be used in a broader range of devices due to its larger capacity, especially those requiring longer battery life, such as:
    • Medical devices (such as glucose monitoring and hearing aids)
    • High-usage remote controllers.
    • Fitness trackers and pedometers.
    • Several electronic toys and gaming gadgets

Interchangeability:

• In some cases, a CR2032 may fit into a compartment meant for a CR2016 (depending on space). However, it is generally not advised because:
  • The bulkier CR2032 may exert pressure on the device's components.
  • The device may not utilize the larger capacity of the CR2032, resulting in wasted battery life.
