10 Best C Batteries 2025 in the United States

The Amazon Basics 24-Pack C Cell Alkaline Batteries are designed to offer reliable power for a variety of everyday devices such as toys, clocks, and flashlights. These batteries operate at 1.5 volts, making them suitable for many household gadgets. One of the standout features is their 5-year shelf life, ensuring that the batteries will be ready to use even after being stored for a significant period. This makes them a convenient choice for stocking up for emergencies or future use.

The product also comes in Certified Frustration-Free Packaging, which is easy to open and reduces the hassle of getting to your batteries quickly. However, it's important to note that these batteries are single-use and not rechargeable. This might be a downside for those looking for more environmentally friendly options or who prefer the convenience of recharging batteries.

While these are good for immediate and reliable power needs, the lack of rechargeability means you'll eventually need to dispose of and replace them. Given their affordable price and practical packaging, they are a solid choice for those needing dependable, everyday power solutions. Just be mindful of the environmental impact due to their single-use nature.

The Panasonic KJ17MCC82A eneloop Power Pack is a versatile battery pack that includes 8 AA, 2 AAA batteries, 2 C and 2 D adapters, an advanced individual battery charger, and a storage case. One of its major strengths is the long-lasting performance of the included eneloop batteries, which can be recharged up to 2100 times. The AA batteries offer a capacity of up to 2000mAh, while the AAA batteries offer up to 800mAh, making them powerful options for various devices. Additionally, these batteries come pre-charged and can retain up to 70% of their charge even after 10 years when not in use, which is a significant advantage for infrequent users.

The advanced charger with individual charging stations and LED indicators ensures each battery gets a perfect charge, enhancing the pack's usability and convenience. However, the product has a few drawbacks. The voltage of 1.5V is standard but may not stand out compared to some high-performance batteries in the market. Additionally, the inclusion of adapters instead of dedicated C and D batteries might not provide the same performance as true C or D batteries.

The environmental impact is positive, given the rechargeability and long lifespan, reducing waste compared to single-use batteries. Weighing 1.51 pounds, the pack is relatively lightweight but the dimensions might make it somewhat bulky for users looking for a compact solution. This product is best suited for users looking for a reliable and long-lasting rechargeable battery solution who also require flexibility in battery sizes with the included adapters.
