Best Rechargeable C Size Batteries

Despite living in an age of integrated recharging batteries in our devices, removable batteries are still a fundamental part of many types of appliance. Replacing C size batteries when they discharge is expensive and time consuming. As battery technology improves, now is the time to explore the world of rechargeable C size batteries.

In the past, rechargeable batteries have not been the best solution for many people because they could not hold charge long enough. That has changed as the technology has improved. These days, a rechargeable C battery is fantastic for boosting lifespan, saving money, and being more friendly to mother nature.

What Are Size C Batteries?

Traditional alkaline batteries are not as common as they once were. Before the development of affordable rechargeable lithium batteries, alkaline versions powered every appliance or gadget. That’s not the case anymore, but still C batteries remain in frequent use. To this day these batteries are used in electronics with a medium charge drain, ranging from instruments, toys, tools, flashlights, and home appliances.

Since 1926, these batteries have been available, with disposable products being the most popular. 1.5V disposable C batteries measuring 50 millimeters by 26.2 millimeters provide long life and high capacity. While rechargeable variants have been available for years, it is only recently they have become viable replacements for disposable batteries.

Thanks to emerging technology, rechargeable C batteries are becoming more popular. That tech is also becoming mainstream, allowing the cost of rechargeable batteries to drop. One of the main developments has been replacing alkaline for 1.2V Nickel-Metal Hydride (NiMH). This new internal composition allows for better capacity that won’t atrophy if it is left inactive.

Rechargeable batteries were previously famous for discharging themselves over time, even when not in use. That no longer happens, at least not on the same scale. NiMH C size batteries hold up to 85% of charge and can do so for months.

Pros of Using Rechargeable C-Size Batteries

Battery Price

At first, it seems rechargeable batteries are more expensive than their non-charging alternatives. And that’s true, the initial cost of purchasing traditional batteries is less. Rechargeable batteries cost more, and you must buy an accompanying charging dock. However, once that initial purchase is dealt with, rechargeable batteries become a wise investment.

Over the course of their life, rechargeable C-size batteries will comfortably pay back your outlay and save you money long term. Because they can go through hundreds of charging cycles, you will not need to buy any more disposable batteries. Over time, you’re looking at saving dozens, if not hundreds, of dollars.

It’s also worth remembering not needing to dispose of batteries every few weeks or months is also better for the environment.

Battery Life

There’s no doubt that a disposable battery lasts longer than a single cycle of a rechargeable one. If you buy a long-life disposable battery, you will see significant gains. However, that does not account for the fact a rechargeable battery will give you hundreds or even thousands of subsequent recharges.

Because a disposable battery cannot be recharged, once it runs out of juice you cannot use it again. Yes, a rechargeable battery may lose a few hours compared to a disposable alternative in terms of how long it lasts, but it makes up for it over time. When your disposable batteries are already in the trash, the rechargeable alternatives will have hundreds more cycles left in them.

That’s an important distinction to make between disposable and rechargeable. All the benefits of disposable batteries are short-lived and upfront. Rechargeable batteries come into their own over mid to long term use.
