• These batteries also power the same variety of devices.
• Their shelf-life is also identical when stored under the same conditions.
• They have the same long-term discharge characteristics of approx. 1% self-discharging rate

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.

Summary

In conclusion, both the battery options have similarities and differences. Both provide long-lasting, reliable power and are an alternative to traditional batteries.

The only difference between CR2025 vs. CR2032 you need to account for when choosing one of these two batteries include:

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

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

Silver-oxide batteries are known for their stable discharge. They’re often used in medical instruments and precision devices.

Mercury-Oxide Batteries

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

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

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.

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.

Package Size

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.

• 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.

Silver-oxide batteries can replace these alkaline batteries, with equivalent batteries being SR44, SR44SW, SR44W, SB-B9, 303, 357, etc. These silver oxide batteries are often used in watches (that explains the W in the label).

The table below indicates different labels and equivalents, depending on the manufacturer.

Note: The indicated labels can change over time without prior notice

Frequently Asked Questions

What Do Letter Suffixes on Cell Batteries Mean?

Consider an example like the SR44W, which denotes a silver-oxide battery. The additional letters that appear in the designation type (W in this case) are indicative of the electrolyte used:

• No letter: means the electrolyte is organic.
• S indicates that the electrolyte is made of sodium hydroxide
• SW may be used in low drain quartz watches without chronograph functions, alarm, or light.
• P means that the electrolyte is composed of potassium hydroxide
• W may be used in high drain cameras, quartz watches, and calculators. In other words, the battery complies with the IEC 60086-3 standard for batteries used on watches.

Besides The Type Code, Which Other Marks Should Be Indicated on Cell Batteries?

Watch (and other cell) batteries contain:

Which of the Two Is Better, SR44 or LR44?

LR44 is the cheaper of the two and enjoys a specialty with toys and general use applications. Conversely, SR44 batteries’ specialty is in marine functions in electronic devices.

This is because LR44 batteries quickly drop below the 1.4V threshold, while the silver-oxide SR44 maintains at 1.55V virtually all the time. That said, it is easier to replace an LR44 with an SR44 than vice versa.

Duracell Button alkaline batteries are the most common in the market. They exist in LR43, LR44, LR54, and 625A sizes, with a 5-year guarantee in storage.

What Dangers Do Button Batteries Pose?

Be careful with children. They are likely to swallow button batteries since they look like coins — making them a choking hazard.

Can Button Batteries Explode?

Yes. Avoid mixing chemistries. Lithium button batteries react when different sizes are combined or when mixing chemistries, leading to overload and bursting.

Can Button Batteries Explode?

Yes. Avoid mixing chemistries. Lithium button batteries react when different sizes are combined or when mixing chemistries, leading to overload and bursting.

CR2430 Battery Features and Specifications

CR2430 batteries are non-rechargeable Lithium Manganese Dioxide (LiMnO2) button/coin-cell batteries featuring physical dimensions of (D x H) 24.5 x 3.0 mm (~0.9646 x 0.1181 inches).

CR2430 batteries feature a nominal voltage of 3.0 volts, a cutoff voltage of 2.0 volts, and a nominal capacity of ~270-320 mAh. as usual with the batteries, an actual capacity depends on the battery age, storage temperature, drain conditions (current, temperature), and similar.

The standard discharge current of CR2430 batteries is ~0.2 mA, while the pulse current depends on the pulse length, but generally, it is in the 7-15 mA range.

Thanks to the Lithium Manganese Dioxide (LiMnO2) chemistry, the CR2430 battery features a very low self-discharge rate (at room temperature), with most brands having a shelf life of 5-10 years. if the storage/discharge temperature is increased, the self-discharge rate is increased, too.

Standard labels of button/coin-cell 24.5×3.0 mm round batteries are CR2430 (IEC) and 5011LC (ANSI), but other labels are used as well, not just for CR2430 batteries, but also for other batteries of this size, but using other chemistries as well.

These labels include DL2430 battery, ECR2430 battery, KCR2430 battery, KECR2430 battery, BR2430 battery, KL2430 battery, LM2430 battery, ML2430 battery, etc.

CR2430 alternative batteries like DL2430, ECR2430, etc., are just customized CR2430 labels used by some battery brands (Duracell, Energizer. ). nonetheless, these batteries are standard CR2430 batteries.

BR2430 vs. CR2430 Battery

The typical capacity of the ML2430 battery is ~100 mAh, with a standard continuous discharge current of ~0.5 mA, a maximum continuous discharge current of ~10 mA, and a maximum pulse current of ~20 mA.

The number of charging cycles varies, but generally, it can withstand at least several hundred charging/discharging cycles.

ML2430 batteries feature the same voltage as CR2430 batteries, better drain features in terms of maximum current, and a larger self-discharge rate.

However, these batteries should not be considered equivalents since devices that use ML2430 batteries often have built-in battery chargers. and charging a CR2430 battery can be dangerous.

For short, if your device uses an ML2430 battery, replace it with an ML2430 battery. If your device uses a CR2430 battery, it can be replaced with an ML2430 battery, but don’t expect it to last a long time.

LiR2430 battery features lithium-ion chemistry, with a nominal voltage between 3.2 and 3.7 volts, depending on the actual chemistry.

Nominal capacity is in the 90-100 mAh range with maximum continuous discharge current up to 20 mA (0.2C).

Charging voltage depends on the battery chemistry, but for the 3.6-3.7V batteries, it should be kept to 4.2 volts or somewhat lower.

LiR2430 batteries may withstand 300-500 charging/discharging cycles using proper battery chargers, even when being discharged almost completely.

CR2430 and LiR2430 batteries should not be considered directly interchangeable unless explicitly stated by the manufacturer of the device in question. voltage difference is not large, but nonetheless, it can cause certain devices to malfunction, or it can even destroy sensitive devices.
