Ⅷ Frequently Asked Questions About C Battery

 

Ⅰ What is a C Battery?

The C battery (also known as the R14 battery) is a type of dry cell battery that is commonly used in medium-drain applications such as toys, flashlights, and musical instruments. A C battery has a length of 50 mm (1.97 in) and a diameter of 26.2 mm (1.03 in).

 

The voltage and capacity of a C-size  battery are determined by the chemistry of the battery and the discharge circumstances  . The rated voltage is 1.5 volts. Alkaline C batteries have a capacity of up to 8000 mAh, whereas rechargeable NiMH C batteries have a capacity of up to 6000 mAh. Zinc-carbon C batteries typically have a capacity of 3800 mAh. The C battery size, like the D battery, has been standardized since the 1920s. Since the 1950s, the AAAAA, and N sizes have been widely used.

 

 

Under current ANSI battery nomenclature, the C battery is marked "14," while in IEC standards, it is designated "R14."

 

Ⅱ Types of C Battery

C batteries are classified into two types: regular (non-rechargeable) and rechargeable. Both C battery types have advantages and disadvantages when compared to one another, therefore it's critical to grasp the distinctions and choose the finest sorts of C batteries for your individual application.

 

2.1 C-Size Primary Battery 

The C-size primary battery is not rechargeable and must be discarded. The battery life of this disposable battery varies depending on its chemistry and other usage variablesAlkaline, Lithium, Lithium Manganese Dioxide, Lithium Sulfuryl Chloride, Lithium Thionyl ChlorideLithium Bromine ChlorideLithium Poly-carbon Monofluoride, Carbon ZincNickel Metal Hydride, and Nickel Cadmium are some of the battery chemistry options for this dry cell.

 

Alkaline

Because of its low cost, wide availability, and ease of use, the Alkaline C battery is a popular primary battery. It can be found on the shelves of nearly every convenience store, retail store, battery wholesaler, and even smaller shops near you. The nominal voltage of the Alkaline C cell is 1.5V. The majority of Alkaline batteries have a longer shelf life. While some are prone to leakage, others have been redesigned to be nearly leak-free and much more robust than before.

 

Primary Lithium

Non-disposable cell versions of primary Lithium or Lithium C batteries exist. These may have a 3.6 volt voltage and different mAh values. The run time of a battery is typically determined by its mAh rating. As a result, a higher grade indicates a longer run time.

 

The following are the primary features of lithium.

 

- Longer shelf life than typical alkaline batteries

- Lasts longer when used in the appropriate applications and equipment

- More expensive than alkaline cells

- Not prone to leakage

 

2.2 Rechargeable C Battery

Lithium-ion, Lithium Polymer, and other Lithium-based chemistries are used in rechargeable C batteries. NiCd (nickel cadmium) and NiMH (nickel metal hydride) (NiMH). Unlike the major variations, rechargeable C batteries are more practical for most people because they are more dependable due to their endurance than disposable ones. As the name suggests, you'll need a compatible charger for your C-size rechargeable batteries. Most convenience stores, direct suppliers, and battery wholesalers sell rechargeable C batteries with chargers in combo packs.

 

When compared to other battery types, rechargeable C batteries are noted for their long-lasting performance and prolonged battery life. Because they may be used for a long period of time, rechargeable C batteries are a much better option because they are less expensive and can be recharged 500 to 800 times.

 

When you buy a rechargeable C battery, it usually comes with a separate charger for your convenience. Alternatively, some, such as flashlights, musical instruments and various toys, are neatly incorporated into the gadget. Rechargeable C batteries come in several varieties, including Lithium-Ion, NiCd, and NiMH.

 

Rechargeable Lithium

Lithium-ion or other Lithium-based battery packs are also available for rechargeable batteries. These are intended for laptops, PLCs, and other similar applications. Rechargeable Lithium cells are typically more expensive than others, but they are lighter.

 

Nickel Cadmium (NiCd)

Nickel Cadmium is a type of rechargeable battery that has a memory effect. It is hazardous to the environment. It also has a low energy density. However, there are still some situations in which consumers prefer NiCd batteries. Consider factors such as low cost, high discharge rate, high temperature, quick charge time, and long life. The majority of consumers and company owners continue to employ NiCd chemistry in their daily activities. These batteries are intended for use in biomedical equipment, power tools, two-way radios, and professional video cameras.

 

Nickel Metal Hydride (NiMH)

Another rechargeable battery with the C standard size is the Nickel Metal Hydride (NiMH) chemistry. It has a higher energy density than the NiCd variety. NiMH batteries are eco-friendly since they contain no hazardous metals and are recyclable. NiMH batteries have a cycle life that spans from 180 to 2000 cycles. The energy density of NiMH batteries ranges from 140 to 300 Wh/L. The specific power of NiMH batteries ranges from 60 to 120 Wh/kg. The "specific power" of the battery ranges from 250 to 1000 Wh/kg. The nominal cell voltage of NiMH batteries is 1.2 volts. C batteries have various voltages in general.

 

Ⅲ C Battery Voltages

Voltage is the electrical charge strength of a battery. Batteries are distinguished by their nominal cell voltages. The nominal voltage of a cell defines the capacity of the battery in ideal conditions.

 

3.1 C 1.5V Battery

Primary C batteries typically have a voltage of 1.5V. C batteries with a nominal voltage of 1.5V are suitable for most everyday household products.

 

Typical Applications:

- Radios

- Toys

- Clocks

- Remote controls

- Musical Instruments

 

3.2 3V C Battery

C batteries with a nominal cell voltage of 3V are uncommon in everyday household applications. They are widely utilized as professional batteries in a variety of industries for a variety of professional applications.

 

 Typical Applications:

- Smart gas meters

- Mining applications

- Monitoring oil tank level

- Petrochemical facilities

- Gas and leak detectors

 

3.3 3.6V C Battery

These batteries have a greater voltage and are intended for industrial and professional use. These are typically made of lithium. These will be used in the next generation of microelectronics. In most cases, the battery's permanent connection to the circuit is intended to ensure the application's reliable functioning across a wide temperature range.

 

Typical Applications:

- Industrial Applications

- Buoys

- Professional Electronics

- Measuring Equipment

- Automatic meter and professional meter readers

 

When it comes to C battery voltages, you may also get NiMH C High Temperature, NiMH raised button high power cell, and many more C cells with 1.2V as the nominal voltage.

 

Ⅳ C Cell Battery VS. 26500 Battery

C cell batteries and 26500 batteries are both cylindrical batteries that are commonly used in home appliances, toys, flashlights, musical instruments, and so on.

 

The chemistry type of C cell batteries and 26500 batteries differs, as do their nominal voltage, capacity, internal resistance (drain type), shelf life, application, and other characteristics.

 

C cell batteries have physical dimensions of 50.0 mm (1.9685 inches) in height and 26.2 mm (1.0315 inches) in diameter.

 

26500 batteries have a 50.0 mm height and a 26.0 mm diameter, whereas 25500 batteries have a 50.0 mm height and a slightly smaller 25 mm diameter.

 

26500 batteries are more prevalent than 25500 batteries due to their greater resemblance to C cell batteries.

 

Because C batteries are larger than AA (50.5 x 14.5 mm) and A (50.0 x 17.0 mm), they can be replaced by these cells with a plastic size adaptor, but capacity will be lost.

 

MN1400 batteries, MX1400 batteries, 343 batteries, U11 batteries, LR14 batteries, R14 batteries14A batteries, 14D batteries, E93 batteries, and so on are all classified as C batteries.

 

C battery, MN1400, LR14, and R14 are the most prevalent labels.

 

Both C cell batteries and 26500 batteries are available in a variety of chemistries and are classified as either primary (non-rechargeable) or secondary (rechargeable).

 

Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH), alkaline (zinc-manganese dioxide, for example), and zinc-carbon batteries are all examples of C cell batteries, whereas lithium batteries are examples of 26500 batteries.

 

4.1 Rechargeable  (Secondary) 26500 Battery

Rechargeable lithium 26500 batteries use a variety of lithium chemistries, including IMR (LiMn204 - Lithium Manganese Oxide), INR (LiNiMnCoO2 - Lithium Manganese Nickel), IFR (LiFePO4 - Lithium Iron Phosphate), ICR (LiCoO2 - Lithium Cobalt Oxide), or any other similar/hybrid (LiNiCoO2 - Lithium Nickel Cobalt Oxide, LiNiCoAlO2 - Lithium Nickel Cobalt Aluminum Oxide, etc.) technology.

 

Their nominal voltage ranges from 3.2 to 3.7 volts, and their nominal capacity ranges from 3.0 to 6.0 Ah - again, some types are designed for low-drain applications, while others are designed for high-drain applications.

 

While both rechargeable and non-rechargeable lithium batteries are interchangeable, devices designed to be powered by C-cell batteries with nominal voltages of 1.2 - 1.5 volts should not be powered by lithium 26500 batteries due to the large voltage difference (more than 2x) – such voltage difference may damage the device.

 

Some newer devices, such as LED flashlights, toys, and portable radios, are designed to be powered by either C-size batteries or 26500 batteries, regardless of voltage difference - these devices feature small DC/DC converters that ensure proper internal voltage is always available regardless of input voltage.

 

Note: Only gadgets that clearly declare that they CAN be powered by C-cell batteries or 26500 batteries should use these batteries. Other gadgets should be powered by only one type of battery, as specified by the manufacturer!

 

4.2 Non-Rechargeable (Primary) C-Cell and 26500 Batteries

Non-rechargeable Zinc-Carbon C cell batteries have a nominal voltage of 1.5 volts and a nominal capacity of 3.0 - 4.0 Ah. They are low-drain C-size batteries that are relatively inexpensive. They also have a shelf life of 2-4 years.

 

The most popular C-size battery chemistry is alkaline non-rechargeable C cell batteries. These batteries have a nominal voltage of 1.5 volts and a capacity of 6.0 - 8.0 Ah.

 

Alkaline batteries are more expensive than zinc-carbon batteries, but they have a higher capacity and a longer shelf life, sometimes 7-10 years or more.

 

Alkaline batteries are designed for medium-drain applications such as LED torches, portable radios, toys, and similar items.

 

Non-rechargeable lithium C size/26500 batteries are generally Lithium Thionyl Chloride (Li-SOCl2) batteries with an exceptionally low self discharge rate (1% per year), great capacity, and the ability to function at low temperatures.

 

Lithium Thionyl Chloride (Li-SOCl2) batteries, on the other hand, have a relatively high internal resistance and are appropriate for low-drain applications.

 

Furthermore, after being on standby for several years, they do not produce their nominal voltage immediately - this duration varies according on the model.

 

Lithium Thionyl Chloride (Li-SOCl2) C cell/26500 batteries, on average, have a nominal voltage of 3.6 volts and a capacity of 8.0 - 10.0 Ah - they can store 2.5 - 3x more energy than alkaline C size batteries.

 

Ⅴ C VS. C2 VS. C4 VS. C8: Are all C Batteries the Same?

C cells are not all the same; some are better suited to specific uses than others, and some last longer when utilized in common applications.

 

Let us distinguish each for a better understanding. C batteries are a form of dry cell battery that is commonly used in portable electronics. They provide power to devices such as flashlights, musical instruments, and other objects that require medium to high consumption rates in order to function correctly.

 

C2 alkaline batteries are the most prevalent type of alkaline battery. They're frequently used in cameras, toys, and other gadgets that require a long shelf life before being recycled or discarded.

 

There are several types of C and C2 batteries, but they are all very similar. The most significant difference is most likely the voltage - C batteries are 1.5 volts each, whereas C2 batteries are 3 volts each. Aside from that, they are nearly the same size. So, if you need a higher voltage battery, go with the C2s; otherwise, either type would suffice.

 

The fundamental distinction between C4 and C8 batteries is that C8 batteries have a higher capacity, which means they can carry more charge. C4s often have a shorter lifespan than C8s. Finally, C8s typically discharge slower than C4s, making them better suitable for high-drain devices such as digital cameras or game consoles.

 

Furthermore, depending on the manufacturer and use, C cell batteries may have varying voltages and capacities.

 

Ⅵ C Batteries Buying Guide

The Most Important Features to Consider

1. Performance

When shopping for new C batteries, one of the first things to examine is their overall performance, which is ultimately determined by two factors: capacity and discharge rate. A C battery's capacity, measured in milliamps per hour, is simply how much charge it can hold before being entirely discharged (mAh). The bigger the mAh, the longer the battery usually lasts. C batteries are only rated at 8,000 mAh capacity. Discharge rate is vital to consider with total capacity because a high-capacity battery is not as good if it discharges at a much faster rate than a low-capacity battery. If you're wondering about the batteries you already own, you may use battery testers to measure their performance.

 

2. Battery Type

When it comes to C batteries, there are just two options: alkaline or rechargeable. Alkaline batteries are the most common and least expensive form of battery. However, they are just one-time usage, so you must dispose of them once they have been discharged. Non-rechargeable batteries are ideal for flashlights and emergency packs. Because you can keep charging rechargeable batteries after they've been discharged, they obviously provide long-term use. There are several varieties of rechargeable batteries available, including lithium batteries, NiMH batteries (nickel-metal hydride), NiCd batteries (nickel-cadmium), and others. For toys and gadgets you know you'll use for a long time, we recommend NiMH rechargeable batteries.

 

3. Shelf Life

Another consideration when purchasing new C batteries is how long they will endure without being used, often known as shelf life. The shelf life of alkaline batteries is the amount of time they can be stored without being used before they must be discarded. When it comes to rechargeable batteries, shelf life is frequently used to refer to how many times they can be recharged before needing to be replaced. We recommend buying C batteries with a minimum shelf life of five years, while the best options have a shelf life of up to ten years.

 

Ⅶ Conclusion

C batteries are cylindrical standard batteries that are larger than AA and AAA dry cells but smaller than D cells. C-size cells are available as both primary and rechargeable batteries. Understand your batteries and the individual battery requirements for your devices. It will assist you in optimizing the performance of both the battery and the gadget.

 

Because each battery chemistry has its own features, a thorough study of battery chemistry, battery design and engineering, brand, and other aspects is critical in obtaining the finest batteries for every application. Proper storage, handling, usage, disposal, and recycling procedures are also essential for everyone to follow.

 

There is no single rule to follow when looking for the best battery in the world because each battery is unique, designed for either low or high-drain applications, and comes with additional features that come at a cost. Choose the best battery replacement for your smartphone. It will not only extend battery life but also the performance of your device.

 

Ⅷ Frequently Asked Questions About C Battery

1. What are C batteries used for?

The C battery (also known as the R14 battery) is a type of dry cell battery that is commonly used in medium-drain applications such as toys, flashlights, and musical instruments. C batteries accounted for 4% of alkaline primary battery sales in the United States in 2007.

 

2.What is C in lithium battery?

The battery C Rating is the current at which a battery is charged and discharged. A battery's capacity is often rated and labeled at the 1C Rate (1C current), which means that a fully charged battery with a capacity of 10Ah should be able to generate 10 Amps for one hour.

 

3. Can you use C batteries in place of D?

If you only have C batteries for your D-battery equipment, a few quarters can occasionally make up the difference. It's hardly a long-term solution, but it'll suffice in a crisis. You'll normally only need 3 or 4 quarters (or less than $1!) for each battery to be modified.

 

4. What is the difference between AA AAA C and D batteries?

This is when the size of the battery comes into play. The D size battery has a higher current rating than the C, AA, and AAA size batteries. Even though an AA battery and a AAA battery both have a voltage rating of 1.5, the AA battery will deliver greater current than the AAA battery.

 

5. Do C batteries have more power than AA?

C Batteries

 

The C battery has the same voltage as an AA or AAA cell (1.5 volts), but it has a milliamp capacity of 8,200. When translated to watt-hours, the figure becomes 12.3 watt-hours, indicating the difference in battery capacity between the smaller AA and AAA batteries and the bigger C batteries.
