Best Rechargeable D Battery

D batteries are the standard-sized dry cell batteries most commonly used in electronic and domestic devices. Unlike wet cells, these batteries do not have liquid but use a different chemistry to store electric charge. They were first invented in 1988. But as you can guess, technological advancement caused improvements in performance, safety, and reliability.

D-size batteries are typically 2.1 inches in diameter and 2.42 inches in length, but slight variations from model to model exist. They weigh about 160-180 grams. And because of their slightly larger size, D batteries are ideal for devices that require high power for a long time. These include the following:

  • Radio transmitters and receivers
  • Electronic motors
  • Electronic toys
  • Megaphones, etc.

These batteries are mostly rated 1.2V, but you can find some with 1.5V. But regarding the capacity, the range is wide. Some D batteries have over 10,000mAh, but you can find some with significantly low charge capacity. They also exist as non-rechargeable, single-use, and rechargeable variants. But in this article, we will focus on the best rechargeable D batteries.

Things to Consider Buying the Rechargeable D Battery

Many factors go into decision-making when looking for a rechargeable D battery to buy. It is not enough to only check the size and buy the first product you set your eyes on. Like many other items, they have specifications and properties that set them apart.

Consider the following when looking for the best rechargeable D battery for any application:

1. Shelf Life and Temperature Tolerance

Most rechargeable D batteries come in a pack of 2, 4, 8, 12, or 24 cells. That means you may not use them all at once. Instead, you will store others for emergencies or during a power outage. But do you want your stored batteries to get damaged? This is where the shelf-life factor comes in.

The longer the shelf-life, the better the battery is. Consider D batteries with more than 5 years of shelf life and high-temperature tolerance. These will remain in an active state long enough until you need them.

2. Battery Performance

The rechargeable battery performance is defined by its voltage rating and capacity. Most are rated 1.2V, but you can also choose 1.5V if that is what your device use.

On the other hand, the D battery capacity varies significantly. If you have the budget, go for ones with 10,000mAh or more. These have enough power to run most energy-intensive devices, such as radio receivers and GPS devices. They can also last long without the need for regular charging.

3. Battery Chemistry

Single-use, disposable D batteries are made of alkaline electrolytes. They are best as a non-rechargeable option, and you should not be convinced to buy an alkaline rechargeable D battery. Instead, go for Ni-MH ones. These have higher power density, negligible memory effect, and are non-toxic.

But if you have more on your budget, Li-ion rechargeable D batteries should be the best for you. These are excellent choices if you need more power capacity and zero memory effects. However, they have relatively low-temperature tolerance compared to Ni-MH batteries.

4. Number of Recharge Cycles

The number of recharge cycles defines the longevity of the rechargeable D batteries. In other words, it indicates the number of times they can be reused before losing the ability to hold a charge. As you can guess, the higher the recharge cycles, the better they are.

Go for rechargeable batteries with 1,000 recharge cycles or more. These ones last longer and can be used many times, saving you trips to the market.

FAQs

Q: Are All D Cell Batteries the Same?

A: No. D batteries are different in many ways. They are only the same regarding the diameter and length, and that is as far as the similarity goes. Some are rechargeable, while others are single-use and non-rechargeable. If you branch into any category, you will realize these batteries differ in capacity, voltage rating, recharge cycles, and other properties.

Q: How Long Do D-size Batteries Last?

A: This depends on the battery capacity. For example, a D battery may be rated 10,000mAh. If your device draws 100mA per hour from it, the battery lasts 100 hours. But their service life depends on the number of recharge cycles and the battery usage. The more frequently you recharge it, the shorter the lifespan.

Q: How Much Does A D Battery Weigh?

A: The D battery weight depends on the chemistry and other components. Typically, it can weigh about 160-180 grams per cell. They are relatively lightweight, which is why they are used in portable devices.

Q: What is the Difference Between C and D Batteries?

A: The main difference between C and D batteries is their size. C batteries are much smaller than D batteries. Also, they have relatively low capacity due to their size. But C and D batteries often have the same voltage rating.

Q: What Household Items Use D Batteries?

A: Most household devices that require more power than C or AA-type batteries can supply use D-size batteries. These include flashlights, lanterns, radio receivers, boomboxes, electric motors, megaphones, toys, robots, etc.
