What is the difference between C and C4 batteries?

It's may not be easy to tell the difference between C and C4 batteries. People often use them interchangeably, but this can be dangerous if you are not familiar with how these batteries work or don't know what you're doing. This blog post will serve as your reference to help you identify both types of batteries to make an informed decision on which is the appropriate one for your needs.

What is the difference between C4 and C batteries?

C batteries, often known as "dry cell" batteries, are a typical kind of battery. These dry cell batteries are commonly used in portable devices. The C-size battery is a popular type that can be found in almost any store and is mostly sold in packs. In addition to being widely available at low costs, these batteries tend to have longer lifespans than other sizes since AA and AAA cells drain much quicker due to their smaller shapes.

If you've ever owned a remote control for your television or any other device that uses batteries and requires C-sized cells, then these are probably the most common type of battery in use today. They're also known as R14s after their designation by an electrical standards body called the International Electrotechnical Commission (IEC).

C4 batteries, on the other hand, appear to be the same as C batteries. A C4 battery has a capacity of 1Ah and will give 4A in max output power. The C4 means that the device includes four C batteries.

Both C and C4 batteries have the same voltage at 1.5V and provide a similar current, and provide power to devices such as toys, portable radios, flashlights, clocks, and more.

What are the types of C batteries?

There are two types of C battery – standard non-rechargeable and rechargeable. Both have their own strengths and weaknesses when compared to the other. They have their own set of advantages and disadvantages. So, before deciding which is best for a certain purpose, it's crucial to fully understand what they all have to offer.

1) Standard / Non-rechargeable C batteries

These batteries are great for powering devices with medium-to-high power consumption needs. These reliable and long-lasting batteries provide a good value, especially when used in high-drain appliances such as digital cameras or flashlights.

Remember that non-rechargeable batteries are not designed to be charged as there is a risk of ruptures, overheating, and, at worst, explosions. Standard alkaline batteries lack the capacity to store excess electrons; once all stored energy has been used up, they become inert. Rechargeables contain chemicals that can hold on to spare charges thanks in part due charging process, which refills their electron reservoirs making them able to recharge again later down the line.

2) Rechargeable C batteries

Rechargeable C batteries are sustainable, reusable, and can be recharged up to hundreds of times. Some rechargeable models come built-in with the device they power, while others require a separate charging adapter for their use. Some examples of these batteries are NiMH (nickel-metal hydride), NiCd (nickel-cadmium), and Li-ion (lithium iron).

How long do C batteries last?

Batteries have a huge impact on our everyday lives, but the answer to how long they last depend on many factors, such as how the batteries are used, the size, and the models attached to them. But on average, a C battery should last more than 18 hours. A standard 1.5v model can discharge at a rate of 200mA (milliamps), which is less than most common devices need to function properly.

The shelf life of a battery will tell you how long it can be kept unused. Primary batteries have the shortest shelf lives, and rechargeable secondary batteries are most effective when used immediately after manufacturing, but their lifespans depend on usage patterns as well.


Batteries are the lifeblood of many appliances and gadgets. Knowing what factors to consider when choosing a battery for your portable device can ensure that you are up with the best one.

In selecting a battery for an application, it's important to know about the various parameters associated with its operation. The actual reality is that there isn't one type of perfect battery suitable for all applications since no particular choice satisfies every parameter involved. If you want to make use of one property found in a certain selection, then naturally, some other properties will suffer and be depleted as well.

Your takeaway here is that you should be aware of what type of battery you are using because it will affect your charging time and how long your device can stay on during use before dying, so make sure you read up on the differences beforehand.
