An Overview On D Batteries
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.
The D Battery Buying Guide
- If you do buy rechargeable batteries, you might want to stick with the same brand when buying a charger.
- Keep batteries out of reach of children and pets.
- Store your batteries at room temperature in a cool, dry place. Some people may swear that keeping them in the refrigerator helps them last, but this isn’t true of all types of batteries (including alkaline) and the moisture inside the fridge might lead to rust, corrosion and leakage you don’t want near your food.
- Insert D batteries properly by matching up the (+) and (-) symbols.
- To preserve battery life, turn off the devices and take out the batteries when they are not being used for an extended period of time.
- Do not use new and old batteries together or mix up different kinds when using them in one device. This could cause them to leak or rupture.
- Some disposable batteries should not be placed in trash or recycling bins. Some can be recycled or taken to local household waste collection points.
