The C battery (or R14 battery) is a standard size of dry cell battery typically used in medium-drain applications such as toys, flashlights, and musical instruments. As of 2007, C batteries accounted for 4% of alkaline primary battery sales in the United States.
These lithium batteries (called primary lithium batteries) are 3.6 volts and are available in either 1/2 AA, 2/3 AA, AA, C or D sizes. They come in many different mAh ratings.
A Lithium Battery may cost 5 times more than an Alkaline Battery, but it will last for about 8 to 10 times longer in operation, with a similar shelf life when not in use.
When comparing rechargeable AA batteries, Gizmodo found that Duracell lasted longer (5 to 6.5 hours) than Energizer batteries (2 to 3.5 hours). Both companies's batteries are NiMH; the Duracells are 2000 mAh and the Energizer batteries are 2200 mAh. mAh stands for milliampere-hours, which is a unit of electric charge.
AAA, AA, C, D batteries all are rated at 1.5 volts but besides the difference in physical size there is a big difference between them all. In an electrical circuit or device, there are two really important things: voltage and current. The D size battery will deliver more current than the C, AA, and AAA size battery.
Performance: Energizer is known in the industry at the longest lasting AA battery but tests have shown that Rayovac batteries perform just as long as Energizer batteries. Rayovac batteries are consistently cheaper than Duracell and Energizer, while maintaining the high quality standards of name brand batteries.
Best Rechargeable C BatteriesNo need to rush to the hardware store when you've got a run-down battery. With rechargeable C batteries, you won't have to worry about buying new batteries all the time. Instead, you'll only have to purchase a rechargeable battery charger just once.
Yes, you can store batteries in ziploc bags. However, it's much better to store batteries in a battery organizer for at home storage. "Place each battery in its own protective case, plastic bag, or package, or place tape across the battery's contacts to isolate terminals. Isolating terminals prevents short-circuiting."
Yes, unused batteries do go bad, meaning that they lose their charge over time. The expiration date on a non-rechargeable battery is typically the date when only 80 percent of the original charge is left.
DO preserve battery life by switching off a device and removing the batteries when it's not being used, and is not expected to be used for extended periods of time. DO practice proper battery storage by keeping batteries in a cool, dry place at normal room temperature.
Keeping NiMH batteries in the freezer can boost battery life by 90%. Alkaline batteries stored at "room temperature" self discharge at a rate of less than two percent per year. So normally refrigerating or freezing them will only help maintain their charge by a tiny amount.
Store them at room temperature or belowMost people store them at room temperature, in a dry environment, which is perfectly fine. The perfect temperature for most batteries is 15° Celsius, but a little warmer doesn't harm your batteries.
If you buy the more expensive batteries, you pay more up front but they last longer. In the end, there's not that big a difference – it's the same amount of energy per price. The Duracell and Energizer cost three times more and lasted three times longer.
Most unused alkaline batteries will last between five and 10 years, while Ni-MH batteries have a shelf life of three to five years of non-use. The greatest threat to keeping batteries in good condition while in storage are environmental factors.
Most battery manufacturers do not recommend storing batteries in the fridge. While the cooler temperature might lengthen the battery life, the moisture from inside the refrigerator could damage the battery in other ways. This precaution will help keep the high humidity inside a fridge away from the batteries.
A: Shelf life varies across our products: Energizer MAX® AA, AAA, C, and D cells last up to 10 years in storage, while our 9V lasts up to 5 years in storage. Energizer®EcoAdvanced® AA and AAA last up to 12 years in storage.
If you've only got C batteries for your D-battery device, you can sometimes make up the difference with a few quarters. It's not a great permanent solution, but it will do in a pinch. For each battery to be adapted, you'll usually only need 3 or 4 quarters (or less than $1!).

A C-rate is a measure of the rate at which a battery is discharged relative to its maximum capacity. A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps.
AA batteries are the same height and voltage as C batteries, so the only thing keeping them from playing nice is their size. Of course, the disadvantage here is that the AA batteries won't last nearly as long as the C batteries. Still, it's better than nothing, and sometimes you just have to work with what you've got.
Common Battery Sizes
- AA Batteries. Also known as “double A”, AA batteries are by far the most popular battery size.
- AAA Batteries. Also known as “triple A”, AAA batteries are the second most popular kind of battery.
- AAAA Batteries.
- C Batteries.
- D Batteries.
- 9V Batteries.
- CR123A Batteries.
- 23A Batteries.
The capacity of a battery is commonly rated at 1C, meaning that a fully charged battery rated at 1Ah should provide 1A for one hour. A C-rate of 1C is also known as a one-hour discharge; 0.5C or C/2 is a two-hour discharge and 0.2C or C/5 is a 5-hour discharge.
D cells are typically used in high current drain applications, such as in large flashlights, radio receivers and transmitters and other devices that require an extended running time. A D cell may be either rechargeable or non-rechargeable.
