How to Decide Which C Battery is the Best for You

It’s doubtful that batteries are anyone’s favorite thing in the world, lol. These things can be vexing, no joke. Aside from the fact that choosing them is a tug of war, as you have to keep your head in the right place with the thousands of promises (real and unreal) made by many manufacturers, there’s also the challenge of performance.

Lots of batteries today come with so many promises and grossly underperforming capacities, which is why we said that batteries are vexing things. Anyway, we are not here today to talk about the many flaws of batteries; we instead want to walk you through getting the best one.

Okay, so whether you need batteries for your drone, or your camera, or your flashlight, or your robot, or for anything else, there are some basic things you must know.

First, not all batteries work for all kinds of devices or projects; you’ll have to get batteries as your device or project demands. And equally important is the fact that batteries contain really toxic stuff, so you might want to be careful about leaking and disposal so you don’t hurt the environment or, even worse, yourself or loved ones.

This guide will teach you how to deduce the capacity of your battery. This way, you’ll know what to expect by reading the values on the pack, and no manufacturer will be able to bamboozle you with cock and bull stories.

There are quite a few things to talk about, so we will quickly move out of the way so you can get the full gist from the other sections of our guide. And as you read through our reviews, don’t forget to keep the Bonai Rechargeable C Batteries in mind. As the name suggests, they are rechargeable and can maintain 80% charge for 3 years while stored. Enjoy!
C batteries aren’t too expensive, thankfully, which means that you do not have to consider getting a cheap C battery. Aside from the environmental hazards they pose, some of these cheap guys might leak, and we all know how toxic that can be, not to mention the obvious fact that they underperform and need constant replacement.

Anyway, with between $5 and $75 or a bit more, you should be able to get a pretty good battery. What affects the cost will usually be the number of batteries you want, of course, and the chemistry of the battery, as we will soon explain. Usually though, alkaline batteries are the least expensive, while Lithium batteries cost relatively more.

Additionally, you can opt for rechargeable batteries, will require a bit more of an upfront investment, but because they don't require replacement as often, in the end you could be spending less overall.

Getting the best C batteries can be a difficult task, but if you look out for these features, then you should be okay. Check them out:
  • Chemistry
  • Nominal Voltage
  • Capacity
  • Discharge Rate
Let’s get into the details already!
Construction and Design
The first thing we will discuss is the chemistry of C batteries. Batteries can be classified into different categories based on their chemistry, and we will see those categories now:

NiMh: This is the most popular of all the categories of batteries, probably because it offers the most value. Also, it’s rechargeable and, because it has next to zero memory effect, it attains full capacity with every charge, without losing any part of its capacity.

NiCd: These guys are getting phased out fast. Although they quite resemble the NiMh, they are quite different in the sense that they have memory effect. So, quite unlike their distant cousins, if you don’t completely drain out the battery, and you recharge it to full capacity regardless, your battery will begin to lose capacity little by little.

Alkaline: A reason this type of battery is quite common, in spite of the hazards it presents to the environs, is that it’s the least expensive of the different types. The only problem is that they are only inexpensive options if you just need them short term; otherwise, the need for constant replacement makes them quite costly options.

Lead Acid: Although pretty weighty, these are high capacity and they are pretty affordable, too.

LiPo: These have started becoming the in-thing in the world of batteries today. One, they are lightweight; two, they have pretty good capacities; three, their discharge rates are really high. But then, you have to be sure that this is the battery you want to use before buying your electronics, as the voltage increases by 3.7volts.
Performance and Ease of Use
Now, nominal voltage: This is the voltage at which a motor delivers its highest power output in relation to its efficiency ratio. When a motor is operated at this voltage, you can be assured of a long life.

Capacity: This helps us determine the length of time a battery will keep working when operating at a particular voltage and when discharging at a particular discharge rate. So, say you choose a 12-volt, 2-Ampere/hour battery set – it means that these batteries will power a motor that consumes 2 Amperes of current for one hour non-stop, or one that consumes 1 Ampere for 2 hours, or one that consumes 0.5 Ampere for 4 hours. You get the trend, right?

Finally, the discharge rate: You have to choose a battery that discharges properly at the required current, else the device to be powered won’t run. So, ensure you look out for that.

By the way, if you are one of those people who really likes to get into the technical stuff, MIT put together a guide to understanding battery specifications that you can check out.

C Battery FAQs

What Are C Batteries?
C batteries are dry cells designed to fit in certain types of devices. Just like AA, AAA, and D batteries, this particular type is used on portable devices. Even though unfamiliar to most people, these batteries tend to outlast the small-sized AA and AAA batteries. The other name for C batteries is the R14s, as designated by IEC (International Electrochemical Commission). They measure 1.97 inches (50 mm) in length and 1.03 inches (26.2 mm) in diameter. The C batteries on the market exist in different voltage levels, namely 1.5 V, 3 V, and 3.6 V.
What Uses C Batteries?
Several devices use C cell batteries. They include torches, cameras, radios, intruder alarms, musical instruments, toys, walkie-talkies, and so on. The kind of battery you choose for a device will depend on the voltage requirement. For example, 1.5-volt batteries are suitable for remote controls, clocks, radios, toys, and torches. The 3-volt cells will do well in various professional applications, including mining, petrochemicals, gas detectors, and gas meters. Industrial applications like buoys, measuring equipment, professional electronics, and utility meters require 3.6-volt batteries.
How Long Will C Batteries Last?
The length of time C batteries will last depends on various factors. For instance, the device in which the methods will determine how fast the batteries get depleted. Also key is the frequency of use of the equipment. For example, the cells will get quickly depleted when used in a radio that is always turned on. Another thing to focus on is the voltage. Obviously, C batteries with a higher voltage will definitely last longer than the rest. When all of these factors are held constant, C batteries tend to last longer than the smaller sized batteries. And finally, if you are using rechargeable c batteries, you can extend the life of your batteries — but they still won't last forever.
Can C Batteries Be Recycled?
Yes. It is possible to recycle C batteries, just like the other battery sizes. Depending on where you live, the local authority may allow you to dispose of the cells as part of the normal garbage collection services. However, other local authorities may require you to take your C batteries to a local collection point or recycling center. There, the cells will be disposed of in the right way. The managers of the recycling centers will break the batteries down, sort the various components, and re-use them to make other batteries.
