Things to Consider Buying the Rechargeable C Battery

Factors to consider before buying a rechargeable C battery exist. These will help you make an informed decision. If the products reviewed in this article are not your choice, you can use this buying guide to help you get the best for the intended purpose.

Consider the following factors when buying rechargeable C batteries:

1. Battery Chemistry

This refers to the formulation or chemical technology the battery uses to store electrical charge. The most common rechargeable battery chemistries include Nickel Cadmium (NiCad|), Nickel Metal Hydride (Ni-MH), and Lithium-ion (Li-Ion). So, which of these chemistries is the best?

NiCad batteries are generally considered toxic and lead to hazardous waste when disposed of because they contain cadmium. They also suffer from the memory effect. That means they don’t discharge completely, leaving behind residual charge with every cycle. This phenomenon shortens their lifespan. Hence, NiCad rechargeable batteries are not an ideal choice.

On the other hand, Ni-MH batteries have higher capacity, are relatively cheaper, non-toxic, and suffer negligible memory effects. These qualities make them an ideal choice for many applications.

Li-Ion rechargeable batteries are another excellent option if you have more on your budget to spend. This relatively new technology leads to higher energy density than Ni-MH and does not suffer any memory effect. They are also non-toxic. However, Li-ion batteries are less tolerant to temperature variations and may spontaneously burst into flames.

2. Voltage and Amp-Hour Rating

Each C battery cell has voltage and amp-hour ratings. Typically, the voltage rating is 1.2V or 1.5V. On the other hand, amp-rating significantly varies. The ones with the least capacity can be below 1,000mAh, while the highest rating may clock 9,000mAh or more. This depends on the company and the battery chemistry. As you would expect, the Li-ion rechargeable batteries would be on the high end of the spectrum.

The amp-hour (Ah or mAh) rating defines the battery’s performance. It represents how much charge the battery can hold and gives a hint on how long it can power any device. Consider higher amp-hour ratings if you want a C battery for a power-hungry application.

When choosing these batteries, ensure you match the voltage rating to the device you intend to power with them. That is, buy a 1.2V battery for a 1.2V device and a 1.5V battery for a 1.5V device.

3. Recharge Cycles and Shelf Life

Recharge cycles of the battery describe its lifespan or the number of times you can recharge and re-use it. The higher the recharge cycle, the longer the battery will last. However, it may also mean spending more to get rechargeable C batteries with over 1,000 recharge cycles.

Shelf life refers to how long they last when not being used. And although Ni-MH and Li-Ion do not suffer from the memory effect, they degrade over time. These batteries have a shelf discharge rate, which defines their degradation over time. Some can retain about 80% of the charge over 3 years, while others have a much less retention rate.

If you are in the market for a rechargeable battery, look for ones with many recharge cycles and low discharge rates, even if it means spending more. These are much more reliable and durable.


How long do C rechargeable batteries last?

C rechargeable batteries typically last 2-5 years and can be recharged hundreds or thousands of times. This depends on the battery chemistry and the brand. But remember that the longer the battery’s lifespan, the more expensive it will be.

Are all C batteries rechargeable?

No. Not all C batteries are rechargeable. They have their single-use, disposable counterparts, which may explode if plugged into a charger. You should check the C battery label to know if it is rechargeable or not before buying or recharging it.

What are C batteries used for?

C batteries have many uses, like any other household and office batteries. You can buy them for medium applications such as toys, robots, flashlights, communication devices, musical instruments, and many other portable electronic devices.

How long do rechargeable C batteries take to charge?

These batteries typically take 1-4 hours to recharge, depending on the battery chemistry, capacity, charger type, and brand. The higher the battery capacity, the longer it will take to juice up.

How many times can you recharge C batteries?

The number of times you can recharge C batteries depends on the battery chemistry. The disposable alkaline ones can only be reused 7-10 times, but some are not rechargeable. On the other hand, Ni-MH and Li-ion batteries can have hundreds or thousands of recharge cycles. Most manufacturers will specify this on the label.

Conclusion: Top 3 Choices

We have come to the end of the best rechargeable C batteries review, and we have a few recommendations for you. Consider the following if you are looking for a new C battery:
