Top 7 Best C Batteries Compared
#1 AmazonBasics C Cell Everyday Alkaline Batteries – Top Pick
WHY WE LIKE IT: The AmazonBasics C Cell Everyday Alkaline Batteries are super affordable and offer long-lasting performance, especially for everyday, low-drain items like toys and candles.
- Very reliable
- Long-lasting battery life
- 5 year shelf life
- Packaging is a little frustrating to open
- Not for high-drain devices
The AmazonBasics C cell batteries offer 1.5 volts and 7,000 mAh of capacity, making them a perfect fit for everyday use on items that don’t drain a lot of power. That makes these best for items like clocks, remotes, flashlights and toys. We were impressed with how long they lasted before becoming completely discharged. Unfortunately, they didn’t perform well on high drain devices like cameras or flash units. It’s best to have backup charging devices, especially on the go, so if the batteries run on empty, you could still have at least one of the best portable chargers as a spare source of power.
The AmazonBasics C batteries also offer a long, five year shelf life for long periods of storage. With such a long shelf life, you can reliably use these batteries’ power in emergency kits without worrying about leaking or other kinds of damage. If we could choose one thing to change about the AmazonBasics C Cell Everyday Batteries, it would have to be the packaging. Even if it seems like a small thing, packaging that’s difficult to open can lead to an unpleasant experience, especially when you need the batteries at that same moment. Compare these with your generic Energizer Max C batteries. Also, check out the best rechargeable aa batteries.

- Long charging time
These Tenergy C batteries really take their premium label seriously. They’re built well and in compliance with standards like UL, CE, RoHS and REACH for battery safety. They also feature a 12 month extended warranty in case you ever run into any problems with them.
We were most pleased with the Tenergy’s performance in cold temperatures, though. They even hold their charge in fluctuating temperatures, from -4 degrees to 122 degrees F, which is even more impressive. Another excellent feature with these C batteries is the lack of memory effect, which happens when the battery “remembers” a lower charge capacity. While you need AA’s in your best electric toothbrush, these are great for other devices.

WHY WE LIKE IT: The Rayovac Fusion alkaline C batteries are the best alkaline options on our list because of their excellent overall performance and longest lasting shelf life of any of the batteries on our list.
- 12 year shelf life
- Rated highest on ANSI performance tests
- Good for high drain
- Discharge quicker in cold weather
If you need batteries that last more than a decade in your home, these Rayovac batteries are the best choice for you. They also rate the best on ANSI average performance tests, which is an impressive achievement on its own. This performance was also reflected in our own research.
One downside we did notice was the lower performance in colder weather, which isn’t very surprising with alkaline batteries. The Fusion C batteries also feature Rayovac’s dedication to quality assurance by being tested twice before leaving the warehouse. And we know that not all batteries are created equal, which is why you might also want to look into the best car battery charger.
How We Decided
To find the best C batteries on the market today, we focused mainly on one thing during our research: how long the batteries lasted. A battery is of no use to you if it doesn’t last long enough to keep things charged longer than a few days. Of course, overall battery life is dependent on what kind of item you’re powering with the batteries so we made sure to create as much consistency as possible when researching. If your battery needs are more intense, take a look at the best D batteries.
We also focused heavily on value with each of the batteries we researched. To measure value, we compared price, number of batteries included in a pack and rechargeable vs. alkaline. Alkaline batteries can offer more value in certain instances over rechargeable batteries because they can be much more affordable and offer more of a single charge, which is what makes them so great for single-use applications. If you’re looking at something like a car battery, the best battery box may be the best pick for you.
C Batteries Buying Guide
The Most Important Features to Consider
One of the first things you should consider when purchasing new C batteries is their overall performance, which ultimately boils down to two things: capacity and discharge rate. The capacity of a C battery is essentially how much charge it can hold before being completely depleted, measured in milliamps per hour (mAh). The higher the mAh, the longer the battery will typically last. C batteries are rated to carry only up to 8,000 mAh capacity. Discharge rate is important to consider alongside total capacity because if a high-capacity battery discharges at a much faster rate than a low-capacity battery, it’s not as good. You can measure the performance of your batteries using battery testers, in case you’re curious about the batteries you already own.
- Battery Type
When it comes to the type of C battery you can purchase, there are really only two options: alkaline vs. rechargeable. Alkaline batteries are the most common types of battery, and they’re also the cheapest. However, they’re also only one time use, so once they’re discharged you’ll need to dispose of them. Non-rechargeable batteries are best for emergency kits and flashlights. Rechargeable batteries obviously offer long-term use because you can constantly keep charging them after they’re discharged. You can purchase a variety of different types of rechargeable batteries, including lithium battery, NiMH batteries (nickel-metal hydride), NiCD batteries (nickel-cadmium) and others. We recommend using NiMH rechargeable batteries for toys and items you know you’ll use for a long time.
- Shelf Life
Another important aspect to keep in mind when getting new C batteries is how long they’ll last without being used, also known as shelf life. For alkaline batteries, their shelf life is how long they last in total without ever being used before you have to throw them away. For rechargeable batteries, shelf life often refers to how many times they can be recharged before needing to be replaced. We recommend purchasing C batteries with a shelf life of at least five years, but the absolute best options offer a shelf life of up to 10 years.
