A 1616 battery does not have an expiration date. It does, however, have an average lifespan. This sort of battery usually lasts between 5 and 10 years.

A CR1620 battery, on the other hand, typically lasts 7 to 10 years. These batteries, obviously, have a longer lifespan. As a result, you'll see it in heavy-duty professions like computer equipment, video cameras, and various communication devices.

CR1616 and CR1620 are both non-rechargeable manganese-dioxide lithium batteries that have the same diameter of 16.0 mm, but they differ in height and thus the capacity and other features like drain currents and similar:

- CR1616 battery: 16.0 x 1.6 mm, 50-55 mAh,

- CR1620 battery: 16.0 x 2.0 mm, 65-80 mAh.

While most battery compartments that can accept a CR1620 battery can also accept a CR1616 battery, it is not recommended to replace a CR1620 battery with a CR1616 battery due to the lower capacity and somewhat lower maximum drain/pulse currents that can cause the device to malfunction.

Like all similar small and shiny objects (another button/coin cell batteries included), CR1620 batteries can be swallowed by kids and pets - that is why these batteries come in so-called 'pets-safe' and 'kids-safe' packages.

Although CR1620 batteries don't contain mercury, cadmium, lead, or any other toxic heavy metals and similar pollutants, they are very dangerous when swallowed - if swallowed, they can cause chemical burns and physical damage to internal organs.

If CR1620 batteries (or any similar battery) get swallowed, immediately contact the nearest emergency center (or doctor), explain what happened, and act according to their instructions.
