The CR2354 is a 3V Lithium coin battery that provides a lot of power for various devices and applications. Wristwatches, medical gadgets, auto keys, toys, calculators, and digital memory backup devices use Panasonic CR2354 batteries. We’ll look into CR2354 batteries in this article, but first, let’s define Lithium Non-Rechargeable 3V Button/Coin Cell Batteries.
Lithium Non-Rechargeable 3V Button/Coin Cell Batteries
Most lithium button/coin batteries are primary (non-rechargeable) 3V batteries. Lithium is the negative electrode, while manganese dioxide or carbon monofluoride is the positive electrode.
The labels of manganese-dioxide lithium batteries begin with the letter ‘C,’ and their operating temperature range is typically between -20°C (-4°F) and 70°C (158°F). 3.0 V is the nominal value, and 2.0 V is the cutoff voltage. A typical example is a CR2032 battery, which is about 225 mAh.
The operating temperature range for carbon-monofluoride lithium batteries usually is between -30°C (-22°F) and 85°C (185°F). The cutoff voltage is 2.25 V, and the nominal voltage is 2.8 V. The BR2032 battery, for example, has an average capacity of 190 mAh.
BR and CR batteries are often compatible, and the slightly lower voltage of BR batteries isn’t a problem for most popular applications. However, BR batteries are preferred over CR#### batteries for equipment that operates in severe temperatures.
Rechargeable lithium button/coin cell batteries have become available on the market. LiR is the most frequent brand name, and the nominal voltage is 3.6 or 3.7 volts. Although they have a smaller capacity than non-rechargeable CR or BR batteries, they may be charged and discharged multiple times (up to or even more than 1000 times). LiR2032 (or LIR2032, ML2032, etc.) batteries have a capacity of 50-80 mAh.
Only use LiR cells to replace CR or BR batteries if the device still works with 3.6V power (instead of 2.8 or 3.0V). This 0.6V differential can cause problems with the device’s operation and potentially harm it. 1000+ charging/discharging cycles, on the other hand, can save you a lot of cash.
What is the CR2354 Battery?
The CR2354 is a 3V Lithium coin battery that can be used in various devices and applications. Wristwatches, medical gadgets, auto keys, toys, calculators, and digital memory backup are common for Panasonic CR2354 batteries.

● Long-term dependability
● Coin Cells: -30oC to +60oC
What is CR2354 used for?
Applications. The LITHIUM COIN CR2354 is used in various applications, including digital watches, calculators, laser pens, vehicle keys, exercise equipment, and medical devices like a clinical thermometer and a tensiometer. The batteries have been shown to operate well in appliances that cannot use traditional batteries.
Which Are Better Silver-Oxide or Alkaline Batteries?
Although silver-oxide and alkaline button/coin cells have identical dimensions and nominal voltages, they differ in capacity, self-discharge rate, operational temperature range, and other factors. Alkaline batteries are used in many devices powered by button/coin cells, and many people ask if these may be replaced with silver-oxide batteries.
When stored at 20-25°C, alkaline batteries have a nominal voltage of 1.5V, a cutoff voltage of 0.9V, and a typical yearly self-discharge rate of 10-15%. Alkaline batteries have a 2-3 years shelf life when stored at an average temperature.
Silver-oxide batteries, on the other hand, have a nominal voltage of 1.55V, a cutoff voltage of 1.2V, and a typical yearly self-discharge rate of 2-10% when maintained at 20-25°C; they have a shelf life of 2-5 years, often even longer, when stored at ambient temperature.
However, it is critical to note that the actual voltage of silver-oxide batteries is relatively stable during discharge, and the output voltage only drops to 1.2V at the very end of the battery life (depending on temperature, current, battery age, and other factors). Silver-oxide batteries are also available in low- and high-drain forms.
Low-drain variants have a very low self-discharge rate (annually) and are designed for devices that don’t require high-drain pulses. The self-discharge rate of high-drain silver-oxide batteries is in the 5-10% range (annually), although they can resist strong current pulses.
Examples are remote controls, essential chain lamps, automotive key fobs, digital watches with LED lights and alarms, and other gadgets that use high-drain batteries. Many brands are transitioning to multi-drain batteries with a low self-discharge rate and the ability to give solid current pulses when required to avoid customer misunderstanding and help them choose the proper silver-oxide battery, thanks to technological advancements.
In addition, silver-oxide batteries have a 10-40 percent higher capacity under the same conditions – due to the more steady output voltage and bigger capacity, silver-oxide batteries have a 15-50 percent higher energy density than alkaline batteries.
So, if you’re wondering whether or not you should switch to silver-oxide batteries, the answer is that it depends. Although silver-oxide batteries are more expensive, I believe the performance improvements justify the price difference.
While modern alkaline and silver-oxide batteries do not contain dangerous metals such as mercury or cadmium, electrolytic reactions can occur, resulting in chemical burns if they are eaten.
Contact the local emergency center, describe what happened, and follow their recommendations if they are swallowed by children or dogs (or anybody else).
Features of Panasonic Lithium Coin CR2354 Batteries
Very stable
After ten years, Panasonic lithium coin CR2354 batteries retain 90% of their original capacity. They are chemically very stable because of lithium and manganese dioxide, which results in very low self-discharge. They tested long-term discharge at all operating temperatures and under low-load discharge conditions.
Applications
From memory backup to digital watches, calculators, laser pens, auto keys, fitness gadgets, and medical equipment like a clinical thermometer and a tensiometer, the LITHIUM COIN CR2354 has a wide range of applications. In appliances where traditional batteries cannot be utilized, the batteries have been shown to operate well.
Powerful
Thanks to the Panasonic lithium coin CR2354 battery, even extremely compact gadgets can now have a powerful energy source. After all, one lithium battery can replace two, three, or even more traditional batteries. The battery also has a high voltage of 3V, meaning it can deliver a lot of power in a small package.
Reliable and Safe
There is a lot of corroborating data on the performance of Cr2354 batteries that short-term accelerated tests cannot determine. These repeated tests were carried out on the various safety and performance characteristics of the Lithium Coin CR2354 and the effects of environmental factors such as temperature. As a result, Panasonic batteries have been approved under the UL safety requirements in the United States, and their excellent reliability and safety have gained great recognition globally.
What to look for when purchasing
Choosing an excellent CR2354 battery is critical when replacing one because the power source is often what determines whether or not the electronic “unit” will function properly in the future. When purchasing a CR2354 battery, it’s critical to remember the following points: The product should be available as soon as possible. The temperature range is as wide as possible while the machine operates. Technical specifications and battery parameters must match those of the replaced battery.

Is it possible to use cr2354 and cr2032 interchangeably?
CR2354 is the number. 3V is the nominal voltage. diameter 23mm, thickness 5.4mm
The nominal voltage of a CR2032: 3V size: 20mm diameter x 3.2mm thickness. It cannot be replaced because of the difference in size.
What’s the difference between a BR2325 battery and a CR2325 battery?
The BR2325 is 22.5mm in diameter, while the CR2325 is 22.9mm. It appears that it will still fit in the holder.
What is the difference between lithium batteries CR and BR?
When subjected to temperatures at the high end of the operating temperature range, CR-type batteries are slightly less resilient than BR-type batteries and can rapidly rise in self-discharge.
Is it possible to use a 1632 battery instead of 1620?
The 1632 battery is identical to the 1620 battery in terms of volts and appearance. Depending on your needs, replacing a Cr1632 with a Cr1620 isn’t a bad idea, but you’ll get less use out of the Cr1620. They’re both 3.0v batteries with a 16 mm diameter.
