From The Manufacturer

Make the good times last with Rayovac Fusion D Alkaline Batteries. From the No. 1 value battery brand in the world, Rayovac Fusion delivers lasting performance to high drain devices. These powerful alkaline D batteries are designed to provide optimal performance in a wide variety of high drain devices. Use these Rayovac D batteries in devices ranging from high-powered toys and stereos to flashlights and more. These alkaline D batteries hold power up to 10 years in storage. With all of that energy inside, these high performance D cell batteries are ready to power the devices you rely on each day.

Overview

D-sized batteries were originally called “flashlight batteries,” but they have much wider applications. These powerful cells are cylindrical in shape, 58 to 61.5 millimeters long and have electrical contacts on both of their ends.

D batteries are used in devices like automatic paper towel dispensers, radio receivers and other high-drain units that have extended running times. Like C and other large batteries, D batteries use 1.5 volts, but D batteries deliver more current.

These batteries can be made from alkaline, zinc carbon, lithium or lithium iron disulfide. Zinc carbon and lithium iron disulfide batteries are disposable, while alkaline and lithium batteries can be rechargeable.

In recent years, rechargeable batteries have become more reliable, longer-lasting and less expensive. They are environmentally friendly and can be charged hundreds of times. Still, many people are more comfortable using disposable ones, because they have longer initial shelf lives.

If you do purchase rechargeable batteries, you will also need to buy a rechargeable battery charger. Some of these are made for specific-sized batteries, while others are universal. Even with the purchase of a charger, rechargeable batteries can save you money, since you won’t have to buy batteries all the time.

A good feature to look for when shopping for batteries is a leak-proof guarantee. These batteries are chemically sealed, which prevents harmful chemicals from escaping the cell. Such substances, if allowed to leak, could ruin your electronics.

You are probably familiar with the best-known names in this market, like Duracell, Rayovac, Panasonic and Energizer, but there are some other good brands to consider. When buying batteries in bulk, be sure to store them properly for optimum performance.
