CR1616 vs CR2025[Video+FAQ]: Differences and Similarities

The CR1616 is a coin cell battery that works in many smaller electronic devices. It is able to power key fobs, glucometers, heart rate monitors, toys, computer backup equipment, and more. One of its most popular uses is in the Honda and Lexus key fobs, but it is also used in many other car brands and devices. Having a battery you can rely on gives you peace of mind. No one wants to run out of power for his or her important devices. With these batteries, you can easily store them long-term so that you always have the power that you need.

Also known as 1616, L28, BR1616, or DL1616 batteries, these coin cell batteries use lithium technology and offer high charge density for longer life.

CR2025 is a coin cell battery. Coin cell batteries like CR2025 have many uses, they are usually used for small portable electronics devices such as:

• wristwatches

• pocket calculators

• automobile keyless entry transmitter

• hearing aids

They are generally of a compact size, 5-25mm in diameter and 1-6mm in height. The name defines the size of the battery as for CR2025, the first two digits are for the diameter and the second for the height or thickness of tenths of mm. Therefore, 20mm is the diameter of CR2025, and 2.5mm is the thickness.

Lithium button or coin cell batteries are a bit more expensive than alkaline, ones but last longer, weigh less, and have a wide operating temperature range.

• Lightweight, High Voltage, and High Energy Density

The battery voltage is 3V, almost double that of normal alkaline or manganese batteries. This means that the number of batteries required for equipment can be halved for maximum space-saving and weight reduction.

• Excellent Discharge Characteristics

Voltage characteristics remain stable even for a long period of discharge, greatly improving the reliability of equipment that uses the battery. Such equipment is also maintenance-free (battery replacement is seldom required).

• Excellent Leakage Resistance

The newly developed battery construction and electrolyte ensure maximum leakage resistance over a long span of time.

• Excellent Long-Term Reliability

Carefully selected active materials are used for the active material as well as for the electrolyte.

• RoHS  Directive / European Directives

This product does not contain Mercury(Hg), Cadmium(Cd), nor Lead(Pb), and conforms to EC regulation values. (Directive 2006/66/EC, 2013/56/EU)

Battery packs are excluded from the RoHS directive (DIRECTIVE 2011/65/EU OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 8 June 2011 on the restriction of the use of certain hazardous substances in electrical and electronic equipment).

pros

It comes with a lightweight coin-looking design

High voltage output

The energy density is very high compared to the size

Slow discharge increases the usable time

Great leakage resistance is included

Ensures long-term reliability

Cons

This battery is allowed for single-use

Non-rechargeable

Because CR1616 batteries and CR2025 batteries have the same voltage, they can be used interchangeably. However, because 2025s are a few millimeters thicker than the 1616s, they might not fit in cartridges that originally included 1616s.

       Although CR1616 should NOT contain mercury or any other heavy metal like cadmium or similar, they are small and compact and even kids can swallow them.

     That is why most manufacturers package their CR1616 and similar batteries in 'child safe' packages which require some strength to be opened without tools of some kind. If these batteries are swallowed, induce vomiting right away and call emergency services and act according to their instructions!
