C Battery Voltage When Dead

Batteries are among the essential things of human life because they give electric power to any object, like a  torch, tv remote, and more, without electricity. Nowadays, you can also use electric bulbs, fans, and other electric appliances with inverters. Most of you know that inverters also operate with the help of battery power. In short, batteries are the most demanding electric appliance. 

The battery industry is also improving due to the high demand for batteries. As per stats, the global battery market is about $50 billion, where over $6.5 billion is granted to secondary or rechargeable batteries.

C battery is among the most demanding batteries in the battery industry due to its versatility and long-lasting power. But it is a universal truth that every battery gets drained or dead. We are sure you might also get curious about when C batteries will die. If you want to know everything about a C battery, including At what voltage a battery is dead and How many volts a dead aa or C battery has, you must read this article.

This article will give in-depth detail about the C battery. This article will also explain the difference between lithium-ion and LIFEPO4 batteries. So let us dive into an ocean of batteries.

C batteries - Overview

C batteries, also known as C-size and R12 batteries, are standard dry cell batteries typically used in medium-drain appliances, like musical instruments, torches, toys, and more. It means you can use these batteries in appliances that require a medium-drain battery.  This type of battery's voltage and storage capacity depends on battery chemistry and discharged conduction. The min voltage is approx 1.5V. Rechargeable NiMH C batteries have a capacity of over 6000 mAh, compared to over 8000 mAh for alkaline C batteries. Zinc-carbon C batteries typically come with a capacity of 3800 mAh.

You might be surprised that C-size batteries often have significantly higher capacities than AAA and AA-size batteries. So if you are considering choosing AA or AAA over a C battery, you must change your thought to get a longer battery life.

We hope that you have now understood the basic information about C batteries. You must read the next section if you are still waiting for confirmation about the C battery voltage dead.

At What Voltage is a Battery Dead

Most people think that the battery becomes dead when its voltage becomes zero. If you are among those, you are wrong because the battery dies even after a lot of juice is left. All batteries, including the C battery, become dead even when they have a few numbers of voltage in them. C batteries generally die when their voltage goes below 1.35 V. Yes, you read it right, 1.35  V.  You cannot use C batteries if their voltage goes below 1.35 or less.

How many volts does a dead AA battery have? 

As mentioned above, all batteries die even though they have a little juice or voltage. This phrase is also applied to AA batteries. AA  batteries have massive demand because these batteries are among the most common types of swappable battery cells today. When the voltage of these batteries goes below 1.35 V, they are considered dead batteries because they stop working at this position. 

You might think that the battery life of these batteries is too short because these batteries only work for 0.15 V. Still, you need to be corrected this here. This is because AA batteries have an average lifespan of 5 to 10 years depending on different vital factors, like high drain or low-drain devices, intensity, and more.

Is LiFePO4 better than lithium-ion?

A lithium-ion battery and LiFePO4 battery are both demanding types of batteries for several purposes. A lithium-ion battery is a rechargeable type of battery that uses a reversible reduction of lithium-ion to store energy. 

In contrast, The lithium iron phosphate battery, commonly called the LFP or lifePO4 battery, is a kind of lithium-ion battery that utilises graphitic carbon electrodes with metallic support as the anode materials and lithium iron phosphate as the cathode material.  Below are the three factors that will help you to decide whether a lifePO4 battery is better than a lithium-ion battery-

1. Energy Density

Energy density is the amount of electricity a battery can provide concerning mass. If the battery has a higher energy density, and a smaller amount of mass, the battery can provide more electricity.

Lithium-ion Batteries have an energy density ranging from 100 Wh/kg to 265 Wh/kg. On the other hand, LiFePO4 batteries have an energy density ranging from 90 to 165 Wh/kg. It means that lithium-ion can provide higher energy density than LifePO4 batteries. 

2. Cycle Life

Cycle life is another crucial factor in finding the best battery for your needs because it indicates the battery life. Cycle life refers to the number of cycles a battery can complete without dropping performance.

One cycle is the process of going from one full charge of the battery to full discharge. A longer cycle life indicates that a battery will last longer, giving you a better return on your investment.

Lithium-ion batteries typically have a cycle life of 300 - 500 cycles. This equates to a period of two to three years, approximately. On the other hand, LifePO4 has a 3000 cycle, which translates into more than 7 years.

3. Cost per kWh

Cost per kWh is the money you spend for every kWh. Using cobalt as electrode material in a lithium-ion battery raises the battery's cost. On the other hand, the lithium iron phosphate battery employs cobalt-free alternatives such as iron and phosphate, which are significantly less expensive.

Conclusion 

It is a universal truth that all batteries, including C batteries, must die after a certain amount of use. But it does not die after its full voltage becomes zero. All batteries die even after a  few numbers of voltage or juice is left in them. This article has covered all the necessary details about C battery voltage. We hope the information provided in this article will help you choose the right battery or cell for your needs or requirements.
