CR2025 vs CR2032: The Differences
Let’s take a look at the difference between CR2025 vs. CR2032.
Differences in Dimensions/Battery Size
CR2032 has a thicker (3.2 mm) battery size than CR2025 (2.5 mm).
Most devices will accommodate both the batteries, but the CR2032 will sit more snugly in the battery compartment.
Battery CR2025 vs CR2032– Differences in Capacity
The CR2032 button battery has a better storage reserve capacity (235 mAh) than the CR2025 (170 mAh).
Your CR2025 will last you a shorter duration than the CR2032. The CR2025 will last for about 2-3 months under heavy load. In comparison, the CR2032 has a battery life of 3-4 months. However, for normal load usage, both the batteries have a storage time of 10 years.
A higher mAh capacity adds to the shelf-life and battery life as well.
Note that not every lithium coin cell battery will drain the same in different electronic devices. This factor will depend on the active device, dynamic loads, material quality applied to the lithium cells in the battery.
While a Lithium battery has a high initial discharge rate, its overall discharge rate is very low. That’s the reason why these batteries last longer than alkaline batteries.
Battery CR2025 vs CR2032– Can I Use a CR2025 Battery Instead of a CR2032?
Both the CR2025 and CR2032 batteries are interchangeable. However, some battery compartments meant for a thinner battery type, such as the CR2025 battery models, might be too small for the CR2032. The opposite is also true, where the CR3032 battery holder might be too big for the CR2025. It will give you an error message on the electrical applications you’re using.
Here’s what to do if you need to fit a CR2025 battery in a CR2032 compartment.
Take a piece of aluminum foil (you can also use another conductor), then push it into the space above the battery. Make sure you place the folded piece on the positive side of the battery.
If you find yourself with a compact size compartment, there’s nothing you can do.
Make note that a CR2025 will last for a shorter duration than the coin battery CR2032.
Another factor to consider is the device you will be using.
If you are powering a simple device like a toy or a remote, then you’d want to use the CR2025. In comparison, the CR2032 coin cell battery might be the preferred choice for active devices such as medical, hearing aids, pacemakers, digital watches, etc. These devices need a long shelf life, quality material, additional charge, and larger capacity.
Checking the appliance manual for the electrical devices will also tell you what typical capacity you need and the lithium battery to use.
Battery CR2025 vs CR2032–Alternate Options
Lithium batteries provide long-lasting, reliable power in comparison to alkaline batteries. However, product for lithium batteries are higher than product for alkaline batteries.
Button cell batteries are also more reliable due to their long-term discharge characteristics of 1%.
Of course, you can’t use a 3V battery to replace conventional batteries like a 12V battery or a 40 kW battery replacement.
In conclusion, both the battery options have similarities and differences. Both provide long-lasting, reliable power and are an alternative to traditional batteries.

A button cell resembles a button, thus the name. It’s a single-cell battery often used to power small devices like hearing aids and wristwatches.
Its diameter ranges between five to 25 mm (0.197 to 0.984 inches), while its height dimensions are between 1 and 6 mm (0.039 to 0.236 inches).
The battery has two terminals:
- The positive terminal is composed of stainless steel and lies at the bottom.
- The negative terminal is insulated and forms the top cap.
Button cells are famous for their longevity. They possess a low self-discharge, which allows them to keep their charge for a long time (especially in cases of inactivity).
Today, we’ll explore button cell batteries, their composition, and the different types.
Battery Cell Chemistry
There are four major categories into which cell batteries are grouped:
Alkaline batteries match other battery types in terms of size. However, they provide less stable voltage and less capacity than their lithium and silver oxide counterparts.
Silver-oxide batteries are known for their stable discharge. They’re often used in medical instruments and precision devices.
Mercury-oxide batteries have stable voltage but are no longer used because of their toxic nature. Incorrect disposal of the battery pollutes the environment.
For example, the United States, through its Mercury Act of 1996, prohibited the use of mercury in favour of mercury-free alkaline batteries.
Zinc-air batteries have the highest capacity compared to others. In addition to the ingredients packed in the cell, these batteries use oxygen from the air as a depolarizer.
They’re termed next-generation batteries, given their potential to hold more energy, their safety mechanisms, and potentially reduced cost per unit.
Battery Chemistry Comparison Chart
|Type||Typical label||Capacity (MAH)||Internal resistance (ohms)||Weight (grams)||Voltage|
|Silver-oxide||SR44, SR44W||150–200||5 to 15||2.3||1.55V|
|Alkaline||LR44, LR1154||100–130||3 to 9||2.4||1.5V|
The Electrochemical System
IEC 60086-3 is an international standard that defines battery cells using an alphanumeric code format.
The IEC 60086-3-5:2021 particularly provides the requirements, dimensions, designation and methods used to test batteries used for watches.
|Code||Name||Positive Electrode||Negative Electrode||Electrolyte||Nominal Voltage (V)||End-point Voltage (V)|
|M,N (obsolete)||Mercury||Mercury dioxide||Zinc||Alkali||1.35/1.40||1.1|
|Z||Nickel oxyhydroxide||Manganese dioxide, nickel oxyhydroxide||Zinc||Alkali||1.5||unknown|
C, S, and L types are primarily used in calculators, quartz watches, small PDA devices, and computer clocks. The P-type powers medical instruments and hearing aids.
R (the second letter in a battery model), defines a cylindrical form.
Rechargeable counterparts identical to primary batteries bear a different prefix that is not part of the IEC standard.
When inspecting a button battery, you may notice a 2-digit code. This represents a typical case size.
A code of 3 or 4 digits speaks for the cell’s height and diameter. In this case, the first 2 digits usually represent the exterior diameter in full millimeters (rounded down). This standard specifies exact diameters with no ambiguity. For example, a cell designated as 9 indicates a diameter of 9.5mm and nothing else.
|Code||Formal diameter (mm)|
- SR516 indicates silver, with 5.8 in diameter and 1.6 mm in height.
- CR2025 indicates lithium, with 20mm diameter, 2.5mm height, and 170 mAH.
- LR1154/SR1154 indicates alkaline/silver with a diameter of 11.6 and a height of 5.4. The alternative two-digit code for this is LR44/SR44.
The Cell Batteries Cross Reference Chart
The LR44 battery is of the alkaline type category, with equivalent batteries being A76, AG13, G13, LR1154, L1154, 154, etc.
