CR1616 vs CR1620 Battery
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.
BR1620 vs LiR1620 vs ML1620 vs CR1620 Battery
BR1620, LiR1620, and ML1620 batteries are very rare batteries and are not commonly used in everyday situations.
BR1620 battery is a non-rechargeable carbon-monofluoride lithium battery, it features somewhat lower capacity and lower drain current than the CR1620 battery, but it has a very low discharge rate and wider temperature range. The nominal voltage of the BR1620 battery is 2.8-3.0 volts and the cutoff voltage is 2.0-2.25 volts, depending on the exact chemistry.
LiR1620 battery is a rechargeable lithium battery, featuring lower capacity than the CR1620 battery, but can be recharged many times. Also, its nominal voltage is 3.6-3.7 volts and not all devices designed for the CR1620 battery support the use of the LiR1620 battery. The self-discharge rate of the LiR1620 battery is up to 5% per month.
ML1620 battery is a rechargeable lithium manganese-dioxide battery, with a nominal voltage of 3.0 volts and can be used instead of a CR1620 battery. However, it is used rarely due to the lower capacity, stronger self-discharge rate, etc.
CR1620 Safety Issues
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.
